GPIO commands not working: "device or resource busy" Hi everybody, I'm using iMX93QSB and i'm tryng to debug GPIO interface of the processor using prebuild linux image. I would like to change the P2_6 pin of the GPIO expander PCAL6524HEAZ which drives the selection pin fo the TMUX used on the board. Thanks to the driver I can see the GPIO expander as the gpiochip 4 and I should be able to move the pins by using libgpiod commands like: gpioset -t0 -c 4 22=1 .  But when I try to access to pin 22 (that is corresponding to P2_6) I receive the following message: so I checked the gpioinfo and I notice pin 22 is used by "consumer = ?": I cannot understand why isn't possible to change a gpio pin that's routed in order to be a selection pin. Can you help me? How can I change my selection mode from command line? Regards, Roberto Re: GPIO commands not working: "device or resource busy" Hello, I have not used device-tree-compiler to decompile .dtb in dts but I suggest you take a look on the next post, it could be helpful. Also, please follow the steps on Yocto user's guide  before use Devshell. Best regards. Re: GPIO commands not working: "device or resource busy" Hello @JorgeCas ,Thanks for answering, Is it possible to modify .dtb file within Linux shell? Someone on the internet suggests to use device-tree-compiler to decompile .dtb in dts, change what you need and then compile it again. But when I try to install with: sudo apt-get install device-tree-compiler, I receive: Can you help me please? Thanks in advance. Best regards, Roberto Re: GPIO commands not working: "device or resource busy" Hello,   That GPIO is used for shared GPIO mux on QSB board.   It is defined here.   To use it, you need to change the definition on that node to make it available.   Best regards.

How to obtain the lockstep status of the S32K342 chip core Hello:         I learned that the S32K342 chip is a lockstep chip, but my customers are obsessed with obtaining the lockstep status of this chip. Because they have functional security requirements, they must ensure that the lockstep function of the S32K342 chip is turned on, so I would like to ask how to obtain the lockstep status of this chip, the information stored in registers or flash memory.                                                                                                                                           Best regret. Re: How to obtain the lockstep status of the S32K342 chip core Thank you very much. This is the answer I want. Re: How to obtain the lockstep status of the S32K342 chip core Hi@xinglong Please take a look at the register:DCM_GPR “DCMROF19” register bit 29 (bit LOCKSTEP_EN): 0 = decoupled mode 1 = lockstep mode

S32K342チップコアのロックステップステータスを取得する方法 こんにちは： S32K342チップがロックステップチップであることを知りましたが、お客様はこのチップのロックステップステータスを取得することに夢中になっています。機能的なセキュリティ要件があるため、S32K342チップのロックステップ機能がオンになっていることを確認する必要がありますので、このチップのロックステップステータス、レジスタまたはフラッシュメモリに保存されている情報を取得する方法を尋ねたいと思います。                                                                                                                                          最高の後悔。 Re:S32K342チップコアのロックステップステータスを取得する方法 ありがとうございました。これが私が欲しい答えです。 Re:S32K342チップコアのロックステップステータスを取得する方法 Hi@xinglong レジスターをご覧ください:DCM_GPR 「DCMROF19」 レジスタ ビット 29 (ビット LOCKSTEP_EN): 0 = デカップリング・モード 1 = ロックステップ・モード

USB0 host mode downstream ports Hello NXP Experts, on p57, Rev. 2.3 of LPC55S2X_LPC552X datasheet it states the following: Section 7.23.1.2 USB0 host controller: Features: "Two downstream ports" Could you please detail what this means? can two devices be connected to same PHY? where can i find more info either as a code or appnote? Thanks in advance! Re: USB0 host mode downstream ports Hello @diego_charles : Thanks a lot for clarification! Re: USB0 host mode downstream ports Hi @manuela_mendez  Thank you for your reply,  Bascially, the number of downstream ports indicated by the datasheet is the  number of physical downstream ports supported by the USB0 in  host controller mode. Below some screenshots of descriptions and diagrams that I found by checking  the USB 2.0 specification, please take a look at its terminology. Personally, I found this figure more explanatory.  Taking the information from above, I  like to see it this more  practical way: according to the spec and the DS specification , we should be able to connect to the host controller a  HUB with  two devices attached to it. Each device would be a downstream port, which upstreams data. I hope this helps, if you are facing any particular issues with your application and our LPC55xx MCU feel free create another thread and we will be happy to check. Diego

I2C Scanner using Processor Expert for S32K146EVB Hello I am working on I2C Scanner by using S32K146EVB using Processor Expert. I am able to initialize I2C and while reading the Acknowledge, it is giving a problem. I have attached my file for your kind reference.. I hope to hear from you soon.. @VaneB @Senlent  Re: I2C Scanner using Processor Expert for S32K146EVB Hi Nibesh, Sorry for not testing it for you in the previous question I2C Scanner using S32K146EVB-Q144. But as I mentioned there, since the LPI2C_init of S32K146_Project_LPI2C configure MCFGR1[IGNACK] to Ignore NACK by default, and its LPI2C_Transmit uses MTDR[CMD]=5 by default:101b  Generate (repeated) START and transmit address in DATA[7:0]. This transfer expects a NACK to be returned. So you can't judge the acknowledgement by polling MSR[NDF](NACK Detect Flag). Please try to test the following code: void LPI2C_Transmit (uint8_t address)/* Transmit ID and expects an ACK to be returned */ { LPI2C0->MTDR = (0x04<<8)|((address<<1)|0); } LPI2C_DRV_MasterInit(0, &lpi2c1_MasterConfig0, &lpi2c1MasterState); LPI2C0->MCFGR1 |= LPI2C_MCFGR1_AUTOSTOP_MASK; //Automatic STOP Generation        for(i=1; i<127; i++)        { //       LPI2C_DRV_MasterSetSlaveAddr(INST_LPI2C1, i, false);        LPI2C_Transmit(i);        delay(100);         if((((LPI2C0->MSR) & LPI2C_MSR_NDF_MASK) >> LPI2C_MSR_NDF_SHIFT)==true)         {         LPI2C0->MSR &= LPI2C_MSR_NDF_MASK;         LPUART_DRV_SendDataBlocking(INST_LPUART2, Space, sizeof(Space), TIMEOUT);         }         else         { sprintf( Buffer,"0x%X", i); LPUART_DRV_SendDataBlocking(INST_LPUART2, Buffer, sizeof(Buffer), 10000);         }        } Best Regards, Robin ------------------------------------------------------------------------------- Note: - If this post answers your question, please click the "Mark Correct" button.

Does the MCU on the evaluation board S32K3X4EVB-Q172 support OTA? Hello, On the schematic of the evaluation board S32K3X4EVB-Q172, the MCU model is S32K344_172MAXQFP. In the S32K3XX data sheet, the mode is defined like this: P/S32K3NNXXT0MPASR.  In the S32K3xx reference manual, the OTA functionality is disabled in CUST_DEL Device Life Cycle. My question is, how to know if the MCU in the evaluation board supports OTA? Thanks! Crane     Re: Does the MCU on the evaluation board S32K3X4EVB-Q172 support OTA? Hi Crane, CUST_DEL: Device (that is, NXP IC) delivered to system integrator (that is, NXP’s customer) for ECU manufacturing and initial configuration. That is to say, the chip on your development board also has this life cycle by default. However, the OTA functionality can be enabled.  I suggest you download S32K3XX HSE and OTA Advance Training from secure file. Also take a look at S32K3_OTA_AB_SWAP_Demostration Best Regards, Robin ------------------------------------------------------------------------------- Note: - If this post answers your question, please click the "ACCEPT AS SOLUTION" button.

How to set Lpi2c speed of S32K312 in RTD5.0? Hi NXP: we're developing project with S32K312 and getting I2C speed issue. I set Lpi2c parameters by reference manual and getting correct speed 1Mbit/s by GUI(Lpi2c_setting.png),but I measured I2C speed about clock waveform(LA_I2C_waveform.png) about 2.667Mhz. Is it correct? thanks. attachment: I2C_setting_from_reference_manual.png Lpi2c_setting.png clock_ip_referencepoints.png LA_I2C_waveform.png current environment: MCU:S32K312/100pin S32DS Product:3.5.0.202207261815 RTD S32KXX:RTD5.0.0.202407261948 BR Nelson Re: How to set Lpi2c speed of S32K312 in RTD5.0? Yes, I'm afraid you shouldn't select LPI2C_FASTPLUS_MODE with 1 Mbit/s because the reference manual says so. Re: How to set Lpi2c speed of S32K312 in RTD5.0? Hi Robin: I modified I2C parameters from fast+ mode to fast mode in master mode, and GUI show 400000(Baud rate), but I measured speed about 385Khz. it looks like not accurate about GUI value and LA value, thanks. attachment: 20250306-2-I2C_Test_S32K312.7z BR Nelson Re: How to set Lpi2c speed of S32K312 in RTD5.0? Hi Robin: just now, I saw reference manual as you posted information(LPI2C master mode operation supports up to fast Mode = 400KHz), so S32K312 only supports fast mode in master mode(Up to 400Khz). if I want to adjust more than 400Khz, it is invaild for usage, Is it correct? thanks. BR Nelson Re: How to set Lpi2c speed of S32K312 in RTD5.0? Hi Robin: I always use I2C master mode as LPI2C_FASTPLUS_MODE which support 1 Mbit/s.however, I created simple project by GPIO and I2C function and set I2C parameters as current project, and also tested I2C speed is about 888~914Khz on our PCB board. now you can change MCU package of attachment from 100pin to 172pin for your EVB testing,thanks. attachment: 20250306-I2C_Test_S32K312.7z BR Nelson Re: How to set Lpi2c speed of S32K312 in RTD5.0? Sorry for the inconvenience. It would be best if S32 Design Studio would warn you when you select master mode but exceed 400 kbps data rate. S32K3XXRM mentioned: •LPI2C slave mode operation supports up to high speed mode = 3.4MHz (3.4 Mbps data rate; effective data rate reduces according to I2C protocol). •LPI2C master mode operation supports up to fast Mode = 400KHz (400 kbps data rate; effective data rate reduces according to I2C protocol). Re: How to set Lpi2c speed of S32K312 in RTD5.0? Hi Robin: I tried to change Clock_Ip_ReferencePoints from custom(8Mhz) to AIPS_SLOW_CLK(30Mhz), and also changes I2C timing that it calculated I2C baud rate 1000000. but I measured waveform about 864KHz. now I confuse about calculating result of Lpi2c GUI. please help us, thanks. attachment: clock_ip_referencepoints2.png LA_I2C_waveform2.png Lpi2c_setting2.png BR Nelson Re: How to set Lpi2c speed of S32K312 in RTD5.0? Hi Nelson, The LPI2C_CLK comes from AIPS_SLOW_CLK. So would you please configure AIPS_SLOW_CLK in clock_ip_referencepoints.png? Otherwise, the S32 Configuration Tool may use the wrong frequency (80MHz CUSTOM) for calculation.
