PNEV7642A and LPC541xx device I2C connection Hello, I’m trying to establish an I2C connection between the evaluation board PNEV7642A and a system based on LPC541xx devices. Pin connections: J46.1 → AD_I2CM_SCL J46.2 → AD_I2CM_SDA J46.4 → GND (Connected to the corresponding I2C pins on the LPC541xx board.) The issue I’m facing is that the I2C bus seems to get stuck — either the data is not received correctly or not received at all. Additionally, when the I2C bus from the PN7642 evaluation board is connected, it appears to pull down the communication of other I2C devices on the same bus. Could this be related to a clock issue (e.g., clock stretching, desynchronization, or incorrect clock/frequency settings)? Initially, I used the clock driver and clock_config files provided in the PNEV7642FAMA software package. Would you recommend using MCUXpresso Config Tools (https://mcuxpresso.nxp.com/) to generate the pin mux and clock configuration? If so, is there any special procedure or configuration required for this setup? Thank you for your help. Re: PNEV7642A and LPC541xx device I2C connection Hi, According to PN7642 Data Sheet, Section 9.6.1.7, I2C Controller interface supports both multi controller and multi controller with target. Latest SDK available (should be v02.15.004) can be found in PN7642 Product Page, under Software section. Available examples for I2C communication are pn76_hostif_i2c (driver_examples > hostif > i2c) and i2c_gpdma_b2b_transfer_master/_slave (driver_examples > i2c). Also, I will recommend you referring to the I2C-bus specification and user manual. Regards, Eduardo. Re: PNEV7642A and LPC541xx device I2C connection Hello Eduardo, I am now getting closer to understanding the root cause. What I actually need is multi-controller (multi-master) I2C communication with DMA. I have already started modifying the I2C driver to handle: • Arbitration lost events • Retry logic • Bus ready checks However, before continuing further development, I would like to confirm: Does the PN7642 support multi-controller I2C operation? If yes, are there: • Any existing SDK examples? • Updated drivers? • Application notes or guidance from NXP? If such resources are available, could you please share them? Thank you in advance for your support. Best regards, Radoslaw Tomasik Re: PNEV7642A and LPC541xx device I2C connection Hi, Please, try using the default source code of the demo (from latest SDK version of each device). I tried to replicate your setup by using: - LPCXpresso54114 Evaluation board -> lpcxpresso54114_i2c_dma_b2b_transfer_master, no modifications - OM27642EVK Evaluation board -> pnev7642fama_i2c_gpdma_b2b_transfer_slave, no modifications Then, connected: PNEV7642A LPCXpresso54114 J46-1 J1-1 J46-2 J1-3 J46-4 J1-7 The communication works as expected: - LPCXpresso54114   - PNEV7642A Regards, Eduardo. Re: PNEV7642A and LPC541xx device I2C connection Hello @EduardoZamora, Did you have a chance to look into the issue? I’ve attached two files showing one I2C message that is sent cyclically. I can see the signal on the oscilloscope connected to the evaluation board pins; however, it does not appear in the receive buffer of the I2C slave software. What could be the reason for this behavior? Please advise. Best regards, Radoslaw   Re: PNEV7642A and LPC541xx device I2C connection Hello @EduardoZamora, Thanks, I’m doing fine — hope you’re doing well too! 🙂 I’m using the i2c_gpdma_b2b_transfer_slave example (from PN7642 SDK > driver_examples > i2c) as a reference for my tests. My goal is to receive data and send a modified response back. I modified the address setting to: slaveConfig.address0.address = 0x00; so that the device can receive all data on the bus. On the oscilloscope, I can see traffic on the bus reaching pins J46.1 and J46.2. Are these pins the correct outputs for I2C communication, or should I use different pins if I only want to receive data? Regarding J54, my current jumper configuration is as delivered (all four jumpers in place): J54 pins 1–3 & 2–4: PN76xx I2CM as leader — default J54 pins 3–5 & 4–6: PN76xx I2CM as follower — optional J54 pins 5–7 & 6–8: PN76xx I2CA (ATX) as follower — default I’ve attached an example of the I2C communication for reference. I hope this helps clarify the situation a bit more. Thank you in advance for your support. Best regards, Radoslaw Re: PNEV7642A and LPC541xx device I2C connection Hello @RadoslawTomasik Hope you are doing well. Could you please confirm if you are using i2c_gpdma_b2b_transfer_master (PN7642 SDK > driver_examples > i2c) demo as a reference for your test? By any chance, have you modified the original source code? What are the pins you are using on the LPC541xx? Can you provide a capture of the I2C communication by using an oscilloscope or logic analyzer? i2c_gpdma_b2b_transfer_master uses a baud rate of 100K. After connecting to LPC55s16 with slave configuration, using pins J46-1 / J46-2 / J46-4, this should be the output: - PN7642 -LPC55s16 Regards, Eduardo.

S32DS 3.6.4 can't found RTD Hello! Recently, I installed S32DS 3.6.4 & RTD 6.0.0. However, when I attempt to create a new app project, I am unable to select RTD. How can I fix it? Re: S32DS 3.6.4 can't found RTD Thank you for your interest in our products and for contributing to our community. According to RTD 6.0.0 Release Notes: So when you create a new project, please make sure you select NXP GCC 10.2.0 in the following step: I hope this information is helpful.

The project cannot be exported as IAR EW I followed the instructions in "HOWTO: Export S32DS Project to IAR EW (S32K14x/S32K11x)", but I couldn't find the "Project Info Export Wizard" option in "Export". Re: The project cannot be exported as IAR EW Hi,  this feature was present in older S32DS with processor expert. I'm not familiar with IAR Workbench, but I assume that you can import project into WB IDE as a ProjectInfo.xml 

Quadrature Encoder Velocity Measurement Hi, I am trying to figure out how to use a timer to improve low speed quadrature encoder measurements on i.MX RT1060. I can see in the reference manual (55.4.2 Prescaler for Slow or Fast Speed Measurement) that there should be some support for low speed measurements using a timer. However, I am having a hard time understanding how I can set this up? Are the some examples since this was posted? If not could you provide a brief explanation of what I need to do? Does the ENC have its own timer or should I setup a separate timer?  What are the steps for setting up such a timer? Thanks! Best regards, Tor i.MXRT 106x Re: Quadrature Encoder Velocity Measurement Hi @Kan_Li , Thank you I have made a support case with the same title as this one.

RT1176 custom board no access to LPUART1 or JTAG/SWD ... I have a custom board, that is very close to the EVKB board, except no USB or MIPI. I cannot seem to access serial downloader mode to use the Secure Provisioning Tool via UART, nor obtain any access via JTAG/SWD for programming. The chip seems to be working, on that there is an ON/OFF button that when held for 5 seconds, or whatever the length is, powers the chip off, and then pressing the button again powers it on. I've double-triple checked everything, and it nearly matches the EVKB board, however one things I noticed that was not done was to connect VDD_MIPI_* or VDD_USB_* to anything, again, as the board doesn't use MIPI or USB. Could not connecting those power pins be causing the problems I'm having with accessing UART or JTAG/SWD? Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... The image I posted is from that red circled area, and I am using the exact components, values as detailed in the EVKB there. Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Hi @application_ninja , In MIMXRT1170-EVKB board  , RC delay time is 30000*0.00000022=0.0066s  =6.6ms. Please check your board, if your board use the same RC delay circuit, Please use an oscilloscope to measure the signal circled in red in the image. Best Regards Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... As an FYI, this is what my delay circuit looks like...  Blue being DCDC_IN and yellow being DCDC_PSWITCH. Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Not sure what you mean by: "VDD_SNVS_DIG is internal LDO output.", so is 0v output correct for this, or not? My custom board is nearly identical to the EVKB except for not using MIPI/USB/AUDIO. I've gone over things many times, just cannot figure out why I cannot get it into serial downloader mode nor use JTAG/SWD to program it. Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Hi @application_ninja , VDD_SNVS_DIG is  internal LDO output. 1: I suggest you can compare your customed board with MIMXRT1170-EVKB board, check the difference. 2: If you have MIMXRT1170-EVKB board, did you try modify the MIMXRT1170-EVKB board same as your customed board? Best Regards Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Apparently VDD_SNVS_DIG is low, and controlled by software, so my design is correct? https://www.nxp.com/docs/en/data-sheet/IMXRT1170BCEC.pdf "The power rail VDD_SNVS_DIG is controlled by software." Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... OK, so it's looking like I'm not getting anything on VDD_SNVS_DIG, not sure why, but any thoughts as to what could cause this off hand? Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... That was going to be my next steps, however quite difficult to test / probe, thus my first questions to see if not connecting those VDD_MIPI_* and VDD_USB_* could be the cause, since everything else seems to power up correctly and I get correct voltages everywhere. Thank you. Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Hi @application_ninja , Could you use an oscilloscope to check if the power-up sequence is normal, especially the RC delay circuit?  Best Regards MayLiu Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Yes, thank you, I have verified all that, I have a positive voltage on BOOT_CFG_0, and have positive voltage on the RXD LPUART1 pin coming from the chip, so everything appears as though it should be working, but I get nothing from the secure provisioning tool, nor from the sdphost tool. All my power rails look good, proper voltages, my ONOFF button works, reset button, just really stumped as to why I cannot program / read the chip. Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Hi @application_ninja , Thanks for your updated information. First, I suggest you follow the HDUG recommended design for your customed hardware development board. Second, please check the Boot Mode pins settings of your custom development board. If you want use the Secure Provisioning Tool via UART, you need set as serial downloader mode. Third,  Only LPUART1 support serial downloader mode. Wish it helps you. Best Regards MayLiu Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Yes, I am aware of that document, but that does not answer my question, and as you have confirmed what the document states, those are "recommendations", they are not listed as "requirements" for proper board operation. So going by the way you have stated and the documentation reads, as "recommended" they do not have to be performed for proper board  / chip operation. Which leads back to my question, could not doing these "recommendations" cause the problems I am seeing? Re: RT1176 custom board no access to LPUART1 or JTAG/SWD ... Hi @application_ninja , Thank you so much for your interest in our products and for using our community. In MIMXRT1170HDUG, it describe that Unused pins recommendation  https://www.nxp.com/webapp/Download?colCode=MIMXRT1170HDUG Please follow the  Recommended connections for unused analog interfaces. Wish it helps you. If you still have question about it, please kindly let me know.  Best Regards MayLiu

NXP s32k312 SRAM MultibitError @danielmartynek  I’m able to hit the SRAM ISR (ERM0_ISR_Handler) for single-bit errors, but the handler is not being called for multi-bit errors. As far as I understand, a non-correctable error event corresponds to a multi-bit error, correct? I can see that the SRAM non-correctable error event bit is set in SR0, but the ISR is not being triggered. Could you please help me understand how to call the multi-bit error ISR? I enabled interrupt notification for SRAM0 in CR0 register also Re: NXP s32k312 SRAM MultibitError Hi @Anitha7, Uncorrectable faults trigger a CM7 fault exception. In the example I linked, I enabled the Bus_Fault exception, but with a lower priority than the priority of the ERM handler so that the ERM handler is called first. I believe this might be the issue in your project. Also, double-check the VTOR pointer and ensure that the ERM interrupt is enabled in the NVIC. You may notice the interrupt pending in NVIC. Re: NXP s32k312 SRAM MultibitError hi @danielmartynek  Multibit means Double bit as per RM I configured the system for an SRAM0 as per your reference. uncorrectable ECC fault occur(NEC0) by setting the corresponding bit in the SRO register. I enabled interrupt notification for NEC0 and single bit event in corresponding CR0 register. After Non correctable ECC fault occurs, control transfers to the system call function, software not working after that until i perform reset. The ERM_1_Handler is not being triggered, even though I have added it. For single-bit errors, the ERM_0_Handler is triggered correctly. What should I do to ensure that the ERM_1_Handler is invoked when a multi-bit (uncorrectable) ECC error occurs? Also, just to confirm — does a multi-bit error(double bit error) always indicate an uncorrectable ECC fault? After Non correctable ECC event occurs i need to perform reset run in ECU in normal mode Re: NXP s32k312 SRAM MultibitError Hi @Anitha7, What do you mean by a multi-bit error? There is one 8-bit checksum for 64bits (8 bytes) of data, it is not possible to detect every posilble ECC error. There is ECC SECDED (Single error correction, Double error detection). Regards, Daniel Re: NXP s32k312 SRAM MultibitError Hi @danielmartynek  VTOR table points to flash memory only during SRAM0 inject uncorrectable ECC fault. I configured the system for an SRAM0 as per your reference example code. uncorrectable ECC fault occur by setting the corresponding bit in the SRO register. I enabled interrupt notification in corresponding CR0 register. After uncorrectable ECC fault occurs, control transfers to the system call function, software not working after that until i perform reset. The ERM_1_Handler is not being triggered, even though I have added it. For single-bit errors, the ERM_0_Handler is triggered correctly. What should I do to ensure that the ERM_1_Handler is invoked when a multi-bit (uncorrectable) ECC error occurs? Also, just to confirm — does a multi-bit error always indicate an uncorrectable ECC fault? Re: NXP s32k312 SRAM MultibitError Hi @Anitha7, I updated the example by adding uncorrectable error injection into SRAM0. https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K344-EIM-ERM-DTCM-SRAM-Baremetal-v3-0-S32DS36/ta-p/2193534 Can you read the VTOR register in your application? The interrupt vector table must not reside in SRAM0 when injecting an uncorrectable ECC fault into the memory. Otherwise, the ECC fault would corrupt the vector table during a fetch leading to another fault exception. Regards, Daniel

S32K1: LPUART BAUD register OSR bits stuck Hi. My target MCU is a S32K144W on the S32K14W-Q064 evaluation board. I'm configuring the LPUART0 baud rate and I'm noticing that I cannot clear the lower 4 OSR bits in the BAUD register. Those bits default to 1 on reset, but should be writable/clearable afterward. I can set or clear the upper OSR bit, but the lower 4 bits are stuck, always set, and can't be cleared through any operation on that register. Spoiler (Highlight to read) Obviously that limits the function of the UART, and makes choosing an appropriate baud rate difficult. I have combed through the documentation several times but I can't find any mention of a restriction on these bits, or a condition that must be satisfied for them to be cleared or changed. Perhaps I missed it. I found 2 other forum posts where a user mentions the same problem (though on a different part). "So i noticed that only  value of 16 and 32 can be set in OSR field (15 and 31), any other value results in getting 16/32." Unfortunately, I don't see a resolution. https://community.nxp.com/t5/Kinetis-Microcontrollers/FRDM-K82F-uart-problem/m-p/845950 https://community.nxp.com/t5/Kinetis-Microcontrollers/LPUART0-baudrate/m-p/792047/highlight/true#M48190 Any thoughts on why these bits are stuck or how I can change them? Thanks for your help! Trevor Re: S32K1: LPUART BAUD register OSR bits stuck Hi Trevor, Thank you for your information. I hadn't noticed before that you can't clear the OSR bit separately; I saw that writing to the BAUD register in the RTD is also done all at once. Best Regards, Robin Re: S32K1: LPUART BAUD register OSR bits stuck Hi Robin, I'm not using S32K1 RTD - I'm configuring the UART directly in the LPUART registers. To clarify, I was trying clear the OSR and SBR bits first (using LPUART_BAUD_OSR_MASK and LPUART_BAUD_SBR_MASK), then set the required bits (using LPUART_BAUD_OSR(x) and LPUART_BAUD_SBR(x)) to get the baud rate that I need. The key is that if you clear all of the OSR bits, it will result in an oversampling ratio of 16, which is the same as the default with the lower 4 bits set. The reference manual says this, but doesn't appear to fully explain what happens when you clear the OSR bits. What I didn't understand was that if you clear all of the OSR bits, the hardware doesn't just interpret that as using an oversample ratio of 16, but instead it literally forces the 4 lower bits back to 1, back to the default setting. So you can't use the typical pattern of masking and clearing those bits first, then setting the bits you need. Instead you have to set the BAUD register all it once with the values that you need in all of the bit groups. So by changing this: IP_LPUART0->BAUD &= ~( LPUART_BAUD_OSR_MASK ); IP_LPUART0->BAUD |= ( LPUART_BAUD_OSR(10u) ); ... To this: IP_LPUART0->BAUD = ( LPUART_BAUD_OSR(10u) | ... ); It looks like it is now working as expected. Thanks again for your help.

Design Studio v3.6.4 - S32 SDK RTM v4.0.2 を追加するにはどうすればいいですか? こんにちは、 私は Windows 11 上の S32 Design Studio の新規ユーザーです。 S32 Design Studio v3.6.4 を正常にインストールし、[ヘルプ] → [S32DS 拡張機能と更新] からいくつかの更新を追加しました。ただし、SDK の利用可能なアップデートはありませんでした。そのため、S32SDK_S32K1xx_RTM_4.0.2.exe (S32 SDKs RTM v4.0.2) を手動でダウンロードしてインストールしました。 Design Studioで新しいS32アプリケーションプロジェクトを作成した後、.mexファイルが見つからないため、コード コンフィギュレータのアイコンが表示されません。その結果、コード コンフィギュレータを開いて GPIO やその他のペリフェラルを構成することができません。 私の目標は、RTM v4.0.2 をインストールして、S32K144 のコード コンフィギュレータを使用して、単純な手続き型 C コード (AUTOSAR スタイルではない) を生成できるようにすることです。RTD の更新は必要ありません。 この問題を解決するにはどうすればよいですか? よろしくお願いします。 Re: Design Studio v3.6.4 - How to add S32 SDK RTM v4.0.2 ? こんにちは、VaneBさん。返信ありがとうございます。DS v3.6.4 をアンインストールし、DS v3.4 をインストールしました。ヘルプ - 拡張機能と更新プログラムで、SDKs RTM v4.0.3 をインストールしました。 Re: Design Studio v3.6.4 - How to add S32 SDK RTM v4.0.2 ? こんにちは@TLHK S32SDK_S32K1xx_RTM_4.0.2 は S32 Design Studio v3.6.4 と互換性がありません。この SDK はもともと S32 Design Studio v3.4 のアップデートとして提供されました。 これを使用するには、S32DS v3.4 用の S32K1xx サービス パック 1 をダウンロードし、S32DS の拡張機能と更新を通じて新しい更新サイトとしてインストールします。 適切な機能を確保するには、対応する IDEs バージョンをダウンロードして使用してください。 BR、ヴェインB

How about MCXW71's wireless UART to connect to APPs other than IoT Toolbox? I've recently been using the WirelessUART routines for the MCXW71, and using the IoT Toolbox it is possible to connect and interact with data normally. I would like to use, for example, a laptop with Bluetooth, or an app for another phone to get the data. The problem I'm having is that using the Bluetooth Assistant, after scanning for the mac of the development board, it disconnects just after connecting. 回复： MCXW71的wireless UART怎么样连接除IoT Toolbox之外的APP Window11, support BT+BLE, even his other bluetooth is possible. 回复： MCXW71的wireless UART怎么样连接除IoT Toolbox之外的APP Hi, @lugl On Windows you can try scanning and connecting using the Bleak tool + Python script approach. Bleak is a cross-platform BLE library that supports working on Windows. You can search online for the relevant information, at present we do not provide ready-made internal scripts for reference. Best regards. Christine.

MIMXRT1042 XJM5B lpuart pin not working Hello everyone, I’m using the MIMXRT1042 XJM5B EVK and working with LPUART1. The LPUART1 pins are connected to the J1 (micro USB port). I’m able to successfully send and receive data on the terminal through the USB connection. However, when I remove jumpers J11 and J13 (which connect the LPUART1 RX and TX lines to the USB interface) to use an external TTL-to-USB converter, I can receive data on the terminal only while debugging. Once I stop debugging and reset the board, the UART no longer echoes the data I send. I observed the same behavior with LPUART4. I enabled the internal pull-up resistors (22 kΩ), but it still didn’t work. When I added external pull-ups on the RX and TX lines, the UART communication worked correctly, and I could see the echoed data on the terminal. Has anyone else experienced this issue or can suggest why it only works during debugging? Re: MIMXRT1042 XJM5B lpuart pin not working Thank you for your reply. I am using the "evkmimxrt1040_lpuart_edma_rb_transfer" SDK example on LPUART4, and I am seeing the same behavior on LPUART1 as well. Re: MIMXRT1042 XJM5B lpuart pin not working Thanks for your updated information. 1: Please use an oscilloscope to check the UART TX and RX signals to confirm whether the waveforms are normal. and also verify the UART baud rate ,please make sure there is no significant deviation. 2: When the issue occurs, please print the UART error logs , and check which LPUART error flags are set. please Kindly provide detailed information such as the specific error flags. 3: Which SDK demo are you using, and have you made any modifications to it? Best Regards Re: MIMXRT1042 XJM5B lpuart pin not working Thank you for your reply, My concern is that when I debug the LPUART4 code, the data on TX and RX works correctly even without an external pull-up. However, after exiting debug mode and flashing the code normally, the received and transmitted data becomes corrupted. Re: MIMXRT1042 XJM5B lpuart pin not working Hi @RajPadmani , Thank you so much for your interest in our products and for using our community. Regarding your question, I check the schematic of MIMXRT1040-EVK,  In the architecture diagram of the NTS0102 (Figure 11), we can see a 10 kΩ resistor. If the UART cable is long or there is significant external interference, it is recommended to add an external pull-up resistor on the RX line to ensure signal stability and avoid communication issues caused by a floating line. Wish it helps you. If you still have question about it, please kindly let me know.  Best Regards MayLiu
