In engineering mode (BOOT0:off, BOOT2:On) I want to update my cortex-m4 firmware from CMD, not an IDE. What is the command to do so?Thank you!Note: I tried using the STM32_Programmer_CLI executable but it keeps seeing the a7 only, I cant communicate with the m4.Note: I think the IDE uses OpenOCD to do so but I can't find how to extract the command line it uses.

I'm having trouble closing a device as per the recommended method.STM32MP> fuse read 0 0                                                         Reading bank 0:                                                                Word 0x00000000: 00000017                       &nbsp

Hello!I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) in production mode to send message between processor but the following message appears in the terminal:/dev/ttyRPMSG0: no such file or directory Can somebody help me?Thanks!

Hi,After installing and running the latest, OpenStLinux discovered a problem with M4. Firmware is loading fine, but the system doesn't create /dev/ttyRPMSGx channel.

Hello,I have a STM32MP157F-DK2 and I'm planning to develop some python applications to run on the A7 processor. I have some questions related to python development for this platform, as I have not found too much documentations regarding this:Software package: Which ST software package do you recommend for python dev? Given that I will not need to cross-compile any C/C++ application with an SDK, can I use the Starter package, or do I need to use the dev package?Will the default starter of dev packages contain the python modules that I will need to connect and read data from Bluetooth devices?Will the default starter of dev packages contain the python modules that I will need to create GUIs for the TFT display?If I need to install a python module that is not present by default on the image, can I do it at run time, or do I need to create a custom distribution package? how?If you have any examples or tutorials for python development for the STM32 they are very welcome. The "hello world" e

Hi, I'm trying to leverage the capability of lower words to be programmed once to one bit by bit to implement a sort of "forever growing counter", not sure if there is a proper naming for this.In the lower OTP zone, if I understood correctly, word 10 and word 11 are for OEM, does that mean that they are totally free to be used?Best regards,Charles

I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shared too?) uses the RM68200 driver which seems to require 1.8V for IO.The LCD I would like to use also requires 1.8V so I'm wondering if I need a high-speed voltage translator or will the STM32MP1 support my LCD?

I just spent a day trying to configure a gpio with internal pullup using gpiolib. Could not get it configured. Then spent 2 days with device drivers and device trees, and got it working. Seems insane to me that configuring gpios should be this complex. Is there an easier way?

I have a customized STM32MP157AAD board with STPMIC1E PMIC.STPMIC1E is pre-programmed to have same NVM as 1A version.After power up, the board can download firmware by CubeMX and run uboot from SD card, even partially boot the linux kernel.However, there is no action to load stpmic-regulator driver after kernel displays this line.[   2.191543][  T54] stpmic1 1-0033: PMIC Chip Version: 0x21There should be no hardware problem because there is proper signal to read version number and turn on DDR powerThe kernel image file itself is tested on DK2 board and has no problem.

I check STM32MP157F-DK2 schematic. Transmit Channels(ETH_TXD0..ETH_TXD3) isn't have termination resistor. Receive Channels (ETH_RXD0..ETH_RXD3 ) is have termination resistor. But you add termination resistor on Transmit Channels in your  application note(AN5031 page 74 ). I confused about transmit channels termination resistor.Please explain this.Screenshots

Hi STM-Team,We are facing problem while using multiple USART in parallel on STM32MP153C running Linux kernel v5.4.Our application contains two separate threads communicating on two separate RS485 ports in parallel at every ~10ms. After further debugging, we were able to narrow down the use-case to writes happening in parallel. The write on one of the RS485 is stuck and it never finishes and the thread is blocked forever.Simplified way of reproducing the issue using Linux script is as follows (2 instances of this running on two separate RS485 (ttySTM3 and ttySTM7) in parallel): -------------------------------------------#!/bin/bashwhile truedo echo -n -e '\x00\x01\x02\x03\x04\x05\x06\x07' > /dev/ttySTM3 # echo -n -e '\x00\x01\x02\x03\x04\x05\x06\x07' > /dev/ttySTM7done---------------------------------------------------------With this script, we can see write on one of RS485 is blocked after few seconds. Only way of recovering from this is to reboot the device. For debugging, when

Hi STM-Team,We are trying to enable/configure HS200/HS400 mode in eMMC on STM32MP157F-EV1 evaluation board.We are using the stm32mp157f-ev1.dts device tree and we have configured the eMMC node as shown in below screenshot. As per the documentation, we came to know that to select HS200/HS200/HS400, VCCQ has to be set to 1.8 V or 1.2 V.So, we have set "vqmmc-supply" property in device tree to 1.8 range regulator i.e. "v1v8" as shown below.------------------------------------------------------------------------ v1v8: ldo6 {                regulator-name = "v1v8";                regulator-min-microvolt = <1800000>;                regulator-max-microvolt = <1800000>;            &

Hi, Community,​SDMMC3 is not working on STM32MP157F-EV1 board.I'm not sure what's wrong.​I can confirm that SDMMC3_CK/CMD/D0 signals are input and output by osilloscope,but SDMMC_FIFO is empty.The following code is part of the SD_SendSDStatus function in stm32mp1xx_hal_sd.cstatic uint32_t SD_SendSDStatus(SD_HandleTypeDef *hsd, uint32_t *pSDstatus) { : : : /* Send ACMD13 (SD_APP_STAUS) with argument as card's RCA */ errorstate = SDMMC_CmdStatusRegister(hsd->Instance); if(errorstate != HAL_SD_ERROR_NONE) { hsd->ErrorCode |= HAL_SD_ERROR_NONE; return errorstate; } /* Get status data */ while(!__HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXOVERR | SDMMC_FLAG_DCRCFAIL | SDMMC_FLAG_DTIMEOUT | SDMMC_FLAG_DATAEND)) { if(__HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXFIFOHF)) { for(count = 0U; count < 8U; count++) { *pData = SDMMC_ReadFIFO(hsd->Instance); ★★★NOT REACHABLE!!!★★★ pData++; } } if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT) { return HAL_SD_ERROR_TIMEOUT

I'm working on project that required SPI with DMA .I'm working on STM32MP157C-DK2 board.I am trying to enable CONFIG_SPI_STM32_DMA macro in my config file getting error in zephyr driver due to DMA has not yet been ported on STM32MP1.Any suggestions.Thanks in advance!!

Hi! I'm really new to this world, so I'll appreciate the simplicity of your answers.I have an STM32MP157F-DK2 at the University and I need to measure a voltage signal and an UART signal. Can I use only the dual Cortex®-A7 32 bits for configuring the board pins? Or do I must use the Cortex®-M4?Either way, I'm having problems with understanding all this. I have finished reading the instalation wikis, what's the difference between working with the Cortex®-M4 with STM32CubeMP1 installed, and working with the Cortex®-A7 32 bits with the Linux Kernell?I need to create a GUI that shows the voltage signal an the UART that represents temperature, but I need the pins of the board for detecting those signals.

Hello everyone,I'm trying to get started with the STM32MP157 with the STM32MP157x-EV1 Evaluation board by following the exact steps shown here.Everything seems to be running smoothly but when I try to flash the microSD card on the board, something happens: Apparently the problem begins allright, but then, after the message saying "reconnecting the device..." nothing happens and the flashing stops.Here's the log:user@STest:~/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/Starter-Package/stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/images/stm32mp1$ STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/FlashLayout_sdcard_stm32mp157c-ev1-trusted.tsv ------------------------------------------------------------------- STM32CubeProgrammer v2.0.0 -------------------------------------------------------------------       USB speed : High Speed (480MBit/s) Manuf.

Hi there,I would be interested to know if there is any guidance or any existing example projects for using the STM32MP1 with an RTOS on the A7 cores. I am interested in the possibility of running an RTOS like ThreadX/SMP on the A7 cores (plus the M4 core separately).If this is possible, can the headers from the MP1 HAL be used? Are the memory-mapped peripherals all still accessible at the same base addresses on both the M4 and A7 sides?And regarding the Vivante GPU, is that possible to drive directly without the Linux driver? Are there any public datasheets? I've seen some open-source projects which have reverse-engineered the opcodes. Are there any more official projects or documentation resources for this device?Many thanks,Roger

Hi, I need help to compile, build and upload a C++ code on an STM32MP157F-DK2 board. Can anyone help me? Thanks

Hi,I am working on this new board, with its Cortex-A7 core, in Eclipse IDE on Windows 10. I understand that this board is mainly developed on Linux.I've looked into STMCubeMP1 package, and some GitHub repos, but I am not able to find the linker file (.ld) and startup file (.s) from projects. All are Cortex M4 coreAny suggestions? Is there an example code about development STM32MP157 with Cortex-A7 on Windows 10?Thanks in advance.

https://github.com/STMicroelectronics/meta-st-stm32mp/blob/kirkstone/classes/fip-utils-stm32mp.bbclassFIP_SIGN_KEY is used to specify the rot key.But if that key is not found (wrong path for example),the bbclass and cert_create silently creates a new rot key,which obviously doesn't match whatever you were using.This is a bit annoying. If a key is specified, there is no use in believing thatthe user wants a generated rot key... If rot keys are not stored and presented during build, and for whatever reason export of keys failed or path seems wrong, this will go undetected.Your build will succeed, but won't start.What's worse is that you'll be stuck without a functioning fip...
