PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Team, Originally, I would like to use PCA9509 as voltage translator of 5V<-->3.3V, but when I checked the details, I found VIL of PCA9509 is 0.15V, which is too low for slave 6# in below schematic. Can you kindly recommend an option with higher VIL? For example, 0.8V or higher.  Thank you.    Kind Regards, Boler Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Guowei, It's great, thanks. Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? HI Boler： You can refer to below: Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Guowei, Thanks for the quick update. I also notice a similar part PCA9306 as NTS0102 , any difference? Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Boler If only for  level translating we have lots: NVT2002.NTS0102: Voltage Level Translators (Level Shifters) | NXP Semiconductors NTS0102 | NXP Semiconductors Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Guowei, I use PCA9509 only for level translating, so I would like to change PCA9509 to a common voltage-level translator, such as TI TCA39306. Can you please advise NXP option in place of TI TCA39306? Thank you. Kind regards, Boler Re: PCA9509: VIL 0.15V is too low for my application, any option with higher VIL? Hi Boler You can consider about PCA9617!

Basics of Bus Fault in S32DS Program Hi team, I was trying to run a simple complementary program on a S32K358 microcontroller using the S32DS IDE. But i'm facing an error called as bus fault in the program. I have attached the highlighted screenshot of the error message below. I ran the same program in an S32K344 evaluation board and there I didn't face such an error. Please explain me this fault and also the solution to this as I'm new to this IDE's programming. It would be really helpful. S32DS-S32PLATFORM #S32K358 #BusFault  Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  I sent you a private message Re: Basics of Bus Fault in S32DS Program Hi @VaneB  This is the Lpspi_Ip_UpdateTransferMode() function in my code Lpspi_Ip_StatusType Lpspi_Ip_UpdateTransferMode(uint8 Instance, Lpspi_Ip_ModeType Mode) { Lpspi_Ip_StateStructureType* State; Lpspi_Ip_StatusType Status = LPSPI_IP_STATUS_SUCCESS; #if (LPSPI_IP_DMA_USED == STD_ON) Dma_Ip_LogicChannelTransferListType DmaTcdList[1u]; #endif #if (LPSPI_IP_DEV_ERROR_DETECT == STD_ON) DevAssert(Instance < LPSPI_INSTANCE_COUNT); #endif State = Lpspi_Ip_apxStateStructureArray[Instance]; #if (LPSPI_IP_DEV_ERROR_DETECT == STD_ON) DevAssert(NULL_PTR != State); #endif /* Transfer mode can be changed when no transfers are in progress. */ if (State->Status != LPSPI_IP_BUSY) { State->TransferMode = Mode; #if (LPSPI_IP_DMA_USED == STD_ON) if (TRUE == State->PhyUnitConfig->DmaUsed) { /* Activate TX DMA and RX DMA interrupt in interrupt mode or disable then in polling mode. */ DmaTcdList[0u].Param = DMA_IP_CH_SET_CONTROL_EN_MAJOR_INTERRUPT; switch (State->TransferMode) { case LPSPI_IP_POLLING: /* Disable DMA major interrupt. */ DmaTcdList[0u].Value = 0u; break; case LPSPI_IP_INTERRUPT: /* Enable DMA major interrupt. */ DmaTcdList[0u].Value = 1u; break; default: /* Nothing to do */ break; } (void)Dma_Ip_SetLogicChannelTransferList(State->PhyUnitConfig->TxDmaChannel, DmaTcdList, 1u); (void)Dma_Ip_SetLogicChannelTransferList(State->PhyUnitConfig->RxDmaChannel, DmaTcdList, 1u); } #endif } else { Status = LPSPI_IP_STATUS_FAIL; } return Status; } The below mentioned are the SPI configurations, SpiDriver   SpiGeneral Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  It seems that your code fails in the Lpspi_Ip_UpdateTransferMode() function. How do you call this function? Also, could you share the SPI configurations? Re: Basics of Bus Fault in S32DS Program Dear @VaneB, Here is the screenshot of the right side of debug window you requested. What could be the problem? Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  Could you share a picture of the Debug tab displayed on the left side of the S32DS during debugging? This tab shows where the code failed. Re: Basics of Bus Fault in S32DS Program Hi @VaneB  In a new custom project file, I'm now experiencing this type of bus and hard fault with the message highlighted as shown, , I haven't connected any peripherals or devices to the custom microcontroller. Do you think that the fault is due to the SPI data not being transmitted/received to the controller? Or is it something else? Re: Basics of Bus Fault in S32DS Program Hi @VaneB  You were right about the failure in the Clock_Ip_init() function. The problem was not with the hardware. The problem was in specifying the right clock frequency in the FXOSC section in the clock configuration tool (which makes the Clock_Ip_init() function). My custom hardware was using 40 MHz oscillator and I was running the code in 16 MHz FXOSC in the clock configuration tool of my program. Once I changed that to 40 MHz and uploaded the code again, the busfault error was gone and the code was running.  Thanks for all the help you have given me sir. I deeply appreciate it. Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  From the shared images I deduce that it is a clock problem because the failure occurs in the Clock_Ip_init() function. To verify if this is the case, test the Clock_Ip_Example_S32K358 making the necessary changes to match your HW. Re: Basics of Bus Fault in S32DS Program Hi @VaneB  As per the Hardware Design Guidelines for S32K3xx Microcontrollers the crystal oscillator design of our hardware seems to be correct. What could be other possible hardware/software reason(s) for the BusFault and HardFault errors? Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  It seems to be a hardware problem. Since the Hard fault occurs during clock initialization, a possible root cause could be the connections of the EXTAL and XTAL pins, for this you can use as a reference the Hardware Design Guidelines for S32K3xx Microcontrollers. Re: Basics of Bus Fault in S32DS Program Hi @VaneB  I ran the Emios_PWM_Ip example code, that comes with the SDK, on my custom board with the S32K358 controller. I'm still getting the same HardFault error mentioned before. What could be the problem then? Re: Basics of Bus Fault in S32DS Program Hi @VaneB  Yes, you are right. I'm using a custom made board which uses the S32K358. What may the problem then? Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  I have flashed your code on my S32K3X8EVB-Q289 and I did not get a bus Fault. Are you using a custom board? Is it necessary to use both Cortex-M7_0_0 (Boot) and Cortex-M7_0_2 files for programming S32K358? No, depends if you want to work with multicore.  Why does the design studio create two files for this processor and only one file for S32K344? Because S32K358 devices have 1 LS core and 1 single core and S32K344 devices have only 1 LS core. So one project is created for each device core. Re: Basics of Bus Fault in S32DS Program Hi @VaneB  I have attached the .zip file of the project that the code is in. I'm using version 4.0.0 of PlatformSDK kit from NXP.  P.S.: Is it necessary to use both Cortex-M7_0_0 (Boot) and Cortex-M7_0_2 files for programming S32K358? Why does the design studio make two files for this processor and only one file for S32K344?? Re: Basics of Bus Fault in S32DS Program Hi @abdul_rahman  BusFault: detects memory access errors on instruction fetch, data read/write, interrupt vector fetch, and register stacking (save/restore) on interrupt (entry/exit). HardFault: is the default exception and can be triggered because of an error during exception processing, or because an exception cannot be managed by any other exception mechanism. If there is no handler for a specific fault, it is escalated to HardFault. As the code works with a S32K344, there could be a configuration problem. If it is possible could you share your project or configurations? Also, which RTD version are you using?  BR, VaneB

evkbrt1170 romapi Hi,  I am using evkbrt1170 to test romapi in flash. To get straight to the point, it is no longer working in rom_api_flexspi_nor_get_config(). After searching the community, I found advice to change FLASH_DUMMY_CYCLES and FLASH_DUMMY_VALUE in evkbmimxrt1170_flexspi_nor_config.c to 0x06 and 0x00, respectively. However, it still doesn't work. It worked without any issues when I previously used evkmimxrt1060_fsl_romapi. Why isn't it working on evkbrt1170? Are there any specific conditions for using it in flash? Additionally, I need to test it in flash, not in RAM. Here is the code I am testing. Please review it. Best regards, Re: evkbrt1170 romapi I agree with your opinion. Thank you very much. Best regards, Re: evkbrt1170 romapi Hi @seobi  Make sure to mass erase the flash memory and let me know your results. I am now able to run the demo fsl_romapi demo from SDK v2.16.0 after doing this. Here are more details from our  SDK team:   Please note you need to ensure flash is on default status(You can erase the flash and click reset button to ensure the default status.) This issue is caused by ROM API use default dummy cycles to read data from external flash. If dummy cycles changed by users, ROMAPI don't know the changes.   Thank you for your patience, if you are still having issues  or comments do not hesitate to get back to me. Diego Re: evkbrt1170 romapi Hi @seobi  I still have not received confirmation  from SDK team regarding demo failure, as our team is currently a little bit busy with more  SDK releases. If a minor version update is required  to the SDK, I still do not have a date yet. However, as soon I get any information, I will get back to you.  Are you still getting issues or require further help to get the demo running? If so, please do not hesitate to let me know.  Previously, I was able to get the demo working for SDK v2.15.x, but I still have not tryed previous workarrounds on latest version.  Thank you for your patience.  Diego. Re: evkbrt1170 romapi Thank you for your detailed response. Could you provide information on the schedule for the related SDK? Re: evkbrt1170 romapi Hi @seobi  We did had issues on  SDK v2.15.x to get the fsl_romapi demo working, as seen on the thread you mentioned, they where related to EVK flash configuration (dummy cycles). As far I know release v2.16.0 should have changes implemented already, to make the demo operate properly.  Which SDK release version are you using?   Did you also get issues running the fsl_romapi demo? Let me try on my end this demo too. Edit: today I ran with issues  the fsl_romapi demo from RT1170 EVKB SDK 2.16.0. I am currently checking this issue, I will get back to you as soon as possible with more feedback regarding the demo.  Thank you for reaching out. Diego Re: evkbrt1170 romapi I confirmed that the ROMAPI functions properly after downloading using the MCUXpresso secure provisioning tool. However, it is not functioning properly when using the IDE. Is there a way to make it work with the IDE?

Industrial i.MX8QM clock frequencies Hi everyone, We are currently doing tests on the MIMX8QM5CVUFFAB and found some strange behaviour regarding clocks. The first thing we noted is that even though the clock is limited to 1.3 GHz for the Cortex A72 and 1.104 GHz for the Cortex A53, the cpufreq driver allows us to set the higher frequency of 1.6 GHz and 1.2 GHz. The SCFW seems to correctly ignore the higher frequencies but this leads to a missmatch between cpufreq and the actual clock rate: root@apalis-imx8-15556460:~# cat /sys/bus/cpu/devices/cpu4/cpufreq/scaling_cur_freq 1596000 root@apalis-imx8-15556460:~# cat /sys/kernel/debug/clk/clk_summary |grep a72 a72_clk 0 0 0 1296000000 0 0 50000 Y cpu4 no_connection_id root@apalis-imx8-15556460:~# cat /sys/bus/cpu/devices/cpu0/cpufreq/scaling_cur_freq 1200000 root@apalis-imx8-15556460:~# cat /sys/kernel/debug/clk/clk_summary |grep a53 a53_clk 0 0 0 1104000000 0 0 50000 Y cpu0 We would expect that this is either solved by a special cpufreq driver or then by a fdt fixup in U-Boot. However, I can't find any of this solutions in the BSP. Can you confirm that this is currently not implemented? A second clocking issue affects the GPU, even though according to the datasheet the GPU should only run at 625 MHz it runs at 800MHz: root@apalis-imx8-15556460:~# cat /sys/kernel/debug/gc/clk gpu0 mc clock: 797983833 HZ. gpu0 sh clock: 996002801 HZ. gpu1 mc clock: 798002539 HZ. gpu1 sh clock: 995989749 HZ. root@apalis-imx8-15556460:~# cat /sys/kernel/debug/clk/clk_summary |grep gpu gpu_shader1_clk 0 0 0 996000000 0 0 50000 Y 54100000.gpu shader gpu_core1_clk 0 0 0 798000000 0 0 50000 Y 54100000.gpu core gpu_shader0_clk 0 0 0 996000000 0 0 50000 Y 53100000.gpu shader gpu_core0_clk 0 0 0 798000000 0 0 50000 Y 53100000.gpu Here the SCFW does not limit the clock, which seems to be a violation of what is written in the datasheet. My expectation would also be here that there is a fdt fixup in U-Boot to address this but I could not find it. Can you confirm that this is currently not implemented?

Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Recently, when using the S32G274 M7 core to read data from flash, I encountered a forced alignment issue. When attempting to read data starting from an address 2n+1, the returned data starts from address 2n. However, reading from address 2n does not have this problem. We are bypassing FEE and directly using the FLS driver to operate the flash. The MCAL version is: SWS32G_RTD_4.4_4.0.2.   Who can help me, thank you. Re: Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Hi @zyz,  great to hear that. Let us know if there is anything we can do to help. Re: Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Hi carlos_o, Thank you for your support. I have already solved the problem on my side. This 2-byte alignment issue is caused by the inherent characteristics of FLASH and is not related to the software. Re: Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Hi @zyz  I recommend try first with the IP functions instead of MCAL, you can see how it works at the Spi_Ip_Transfer example. Let me know if the issue persists.  Re: Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Hello carlos_o, Yes, I am using our custom board with QSPI DDR mode. The flash model is MX25UW51245G.   I discovered this issue when directly using FLS. Re: Flash Read Alignment Issue - Data Reads from 2n Instead of 2n+1 Hi @zyz, Are you using a custom board? if not is it an RDB or EVB?  If you are using a custom board, which model of QSPI are you using?  The problem is when you are doing the bypass of the FEE driver and using directly the FLS? or this is a workaround?

Regards. Re: S32K3 FlexCan in Polling mode Hi @Kazarian, I understand you are creating your own functions implementing the RTD. Even though it is working, the abort mechanism provides a safe way to request the abortion of a pending transmission. A feedback mechanism is provided to inform the CPU whether the transmission was aborted, or the frame could not be aborted and was transmitted instead. There is an existing polling example (although it is based in S32K312) in the following community post: Example S32K312 CAN Transmit & Receive Using Polling mode DS3.5 RTD300 - NXP Community. It implements both write and read in polling mode like this: rx_info.is_polling = TRUE; //Dinesh FlexCAN_Ip_Send(INST_FLEXCAN_0, TX_MB_IDX, &rx_info, MSG_ID, (uint8 *)&dummyData); // Polling while(FlexCAN_Ip_GetTransferStatus(INST_FLEXCAN_0, TX_MB_IDX) != FLEXCAN_STATUS_SUCCESS) { FlexCAN_Ip_MainFunctionWrite(INST_FLEXCAN_0, TX_MB_IDX); } // Polling while(FlexCAN_Ip_GetTransferStatus(INST_FLEXCAN_0, RX_MB_IDX) != FLEXCAN_STATUS_SUCCESS) { FlexCAN_Ip_MainFunctionRead(INST_FLEXCAN_0, RX_MB_IDX); } Nevertheless, if your configuration is working, there should be no problem. Best regards, Julián

Can not find the driver Hello,   I meet a problem as the attached picture, I need some help to solve it, Thanks.  Re: Can not find the driver @Senlent  Thank you, I don't know what happend to my project just after a PC restart or some other system issue yesterday and I have done a reactivate to S32DS v3.4 too, However I tried to create a new empty project and migrate my project and it take effect, the problem resolved. Thank you Re: Can not find the driver Hi@jinT This kind of problem may can be solved by click "update code". If click "update code" can't solve your problem , i will help you to check it if you can provided the project.

Regarding the limitations of Key Scramble settings Hi NXP According to NXP application note, OTFAD_KEY_SCRAMBLE and ALIGN were arbitrary word and byte. But when I set non-SPT default values (0x33AA55CC & 0x1B), the RT10101 fails to decrypt and boot .[On my EVT board] .It stops in ISP mdoe. =================================================================== On the NXP RT1010 EVB, writing the default settings(0x33AA55CC & 0x1B) allows it to boot successfully. The following are the steps on NXP EVB Step 1. Burning fuses[OTFAD KEK & SCRAMBLE] => boot successfully. Step 2. Burning fuses[HAB] => boot successfully. =================================================================== On non-NXP EVB device, writing the non-default settings ,the RT10101 fails to decrypt and boot and stops in ISP mdoe. The following are the steps on my EVT board Step 1. Burning fuses[OTFAD KEK] => boot successfully. Step 2. Burning fuses[HAB] => boot successfully. Step 3. Burning fuses[SCRAMBLE] => boot Fail. I use SPT for programming, and during the programming process, it will verify that the SPT fuses settings match the device. Therefore, my settings should be correctly written to my EVT board. Using the SPT OTP setting function, I also confirmed that my settings were successfully written to the eFuses. I tried changing the OTFAD encryption block to an unwritten block (e.g., 0x60020000), and my EVT board can boot normally. =>This indicates that there might be an issue with the decryption process. =================================================================== Based on the above successful and failed boot cases: 1. Does the order of writing eFuses affect the functionality of OTFAD and Scramble? 2. Are there any configuration limitations for OTFAD_KEY_SCRAMBLE and ALIGN? Does this mean there is an issue with OTFAD and Scramble? Re: Regarding the limitations of Key Scramble settings Hi Stefano, Here is an update for your problem: for i.MX RT116x/7x, the image_enc utility was replaced by nxpimage already in SEC v7. That's why SEC v7 produces same problem in keyblob as SEC v10. For RT117x kindly use SEC v6. You can still use the processor with your custom fuses, only the keyblob needs to be fixed (bootable_images\otfad_keyblobs.bin).  Alternatively, it shall be also possible to generate keyblob in SEC v6 and replace the keyblob generated by SEC v10 (it is possible to add hook into SEC v10 build script). To do this, you must have all keys and all OTFAD parameters same in both workspaces. We are sorry for inconvenience Re: Regarding the limitations of Key Scramble settings Hello Marek, I can confirm that image produced with V7 using a scramble value of 0x19a8c836 and a scramble align of 0xd6 doesn't work - while using the default values the image works. Note however that I used different keys and random counter. I carefully checked fuse settings on the non-working board (the one with the mentioned scramble values) and they look correct. Apparently, image_enc tool is producing a bad key blob. As a side note, I am surprised that issues on such a sensitive topic (image protection) are not being appropriately addressed: how is it possible that, although ages have passed, it is still not possible to reliably get a correctly formed bootable image from SPT? Best regards, Stefano Re: Regarding the limitations of Key Scramble settings Hi Stefano, scramble for RT116x/7x and RT10xx is confirmed bug in MCUXpresso Secure Provisioning tool v10 and currently there is not planned any hotfix. RT117x is supported since MCUXpresso Secure Provisioning tool v5, so we recommend to use older version (v7). There is not known such problem for image_enc tool. For the input image, kindly follow the description in chapter 6.2.1.1 and disable XIP_BOOT_HEADER_ENABLE (images with the header are not supported in tool version 7). We are sorry for inconvenience Re: Regarding the limitations of Key Scramble settings Hello, having same trouble on rt1176 using SEC V10 - can you confirm the problem still exists on V10? Besides, since V7 does not accept binary images with boot header nor ELF files (at least, not those built within MCUXpresso IDE v11.9.0 Build 2144), I'm having hard times with V7 too - and the encrypted image (from blinky sample) does not work anyway. Looks like older image_enc tool suffers the same bug with some scrambling value and/or align. I am quite surprised this issue has not been addressed yet, since it is actually a security flaw - scrambling is definitely useless if you can (safely) use only default values. Kudos Stefano Re: Regarding the limitations of Key Scramble settings Hi Omar, yes, use SEC v7. The problem is in nxpimage utility, which is used to generate keyblob since SEC v8. In the older versions, keyblob was generated using image_enc utility. Re: Regarding the limitations of Key Scramble settings Hi @marek-trmac     I am using SPT V9.0.1.  Do you mean that I need to use version V7.0 to generate the correct keyblob data based on my scramble values ?  Re: Regarding the limitations of Key Scramble settings Hi Omar, we confirm the problem, we found the keyblob is generated wrongly for same scramble values. The problem is reproducible since SEC tool v8. Could you use SEC tool v7? In version 7 the tool uses image_enc utility to generate the keyblob and there is no such issue. We are sorry for the inconvenience. We'll fix the problem for next release. Re: Regarding the limitations of Key Scramble settings Hi @marek-trmac  Thank you for your reply.  what ALIGN fuse value did you burn? =>Since the setting values are intended for future production, it is inconvenient to disclose them. I can only say that I have set them within the range of 0x00 to 0xFF. Does default OTFAD settings works on your custom board? =>Due to concerns about causing the aforementioned situation again, I am currently not burn any scramble config( OTFAD_KEY_SCRAMBLE and ALIGN) to the custom board. Re: Regarding the limitations of Key Scramble settings Hi Omar, what ALIGN fuse value did you burn? Does default OTFAD settings works on your custom board? Re: Regarding the limitations of Key Scramble settings Hi @marek-trmac      Thank you for your reply.     I have used SPT to erase the flash in the above steps, and then used SPT to rewrite the updated KEY blobs and firmware. Re: Regarding the limitations of Key Scramble settings Hi Omar, after you burn SCRAMBLE, you need to update key blobs (because key blobs are affected by the SCRAMBLE). There is application note with details about OTFAD encryption on RT101x, which might help: AN12670 How to use encrypted XIP boot.in i.MX RT1010 About ALIGN, please refer to chapter "Key blob KEK details" in Security Reference Manual.

ADC SC1 への DMA 書き込み 皆さん、こんにちは サンプリングしたいADC入力は>8個あり、FTM PWM INITトリガと同期しています。 これにはPDBを使用しています。しかし、W 以外の S32K を使用しているため、PDB で CH0 と CH1 をバックツーバック リンクすることはできません。 私は、DMA(ADC COCOによってトリガーされる)がADC_SC1nを書き換えて、より多くの入力をパルスごとに「リンク」する解決策が機能することを考えました。しかし、DMAを介してSC1nに書き込むと、PDBがADCを再度トリガーできなくなるようです(最初のチャネルのESがハイになります)。 これを達成する方法について誰かがアドバイスできますか? ありがとうございます ジョーイ

Calibration features Hello,  I wonder if FreeMaster is capable of being used as a calibration tool. For example, calibrate a thermistor with a NXP board.  Another question on top of this: is it possible to apply a function to a raw signal before it is displayed on a graph in FreeMaster? Thanks  Re: Calibration features Hi @Vast-Horizon, Yes, you can use FreeMASTER as calibration tool. Here's an example of how it could be used in such scenario: Implement the algorithm in the embedded application Store algorithm parameters in global volatile variables Use FreeMASTER to read algorithm parameters at runtime Use FreeMASTER to update parameter values to fine tune the algorithm You can also apply transformation functions on the variables before those are displayed. This option is available in the Variable menu (Project -> Variables -> Edit): Note: transformations are applicable only to REAL values (top right option) Hope it helps, Iulian

About MC33PT2000 software：BASIC-FRDMPKPT2000EVM We used the same PSC assembly code in the file(BASIC-FRDMPKPT2000EVM) with the PT2000 IDE to generate the PT2000_LoadData.c file, but it is different from the file in BASIC-FRDMPKPT2000EVM, as shown in the picture.  user code: Original: The number of arrays is different. One is unsigned short PT2000_code_RAM1[105], another is  unsigned short PT2000_code_RAM1[107]. Is there an error in the document assembly code? Can you provide consistent code? Re: About MC33PT2000 software：BASIC-FRDMPKPT2000EVM Thank you！ I didn't changed anything on  BASIC-FRDMPKPT2000EVM Project. The download address: The Original C code: But,Both methods worked, so the issue is resolved. Thank you very much! Re: About MC33PT2000 software：BASIC-FRDMPKPT2000EVM Hello Hongyu, Where did get your BASIC-FRDMPKPT2000EVM Project? For PSC assembly code, we usually call it microcode. Can you share your SW project here? I think you have changed something on your  BASIC-FRDMPKPT2000EVM Project but you didn't notice. Or you can generate a new BASIC-FRDMPKPT2000EVM Project as below way and try it again And below is the Original RAMx section as your first page. Re: About MC33PT2000 software：BASIC-FRDMPKPT2000EVM Hello Hongyu, I have asked our application engineer who is in charge of the PT2000 to look into it. He is currently OoO, but will be back next week.  Thank you in advance for your patience. BRs, Tomas
