Hi,I'm using brand-new, unmodified st32mp257f-dk dev board.When using starter package (https://www.st.com/en/embedded-software/stm32mp2starter.html#get-software) flashed onto sdcard according to https://wiki.st.com/stm32mpu/wiki/How_to_populate_the_S...
Dear All,I have a total of 8 boards with eMMC from Alliance Memory. All of them boot from SDCard and work well. On 4 of them eMMC is detected correctly and boots fine with 50Mhz/8bit/ddr speed.4 boards are failing in exactly the same manner, that is:...
Please check STM32MP157F-DK2 no function issue after STM32MP157F-DK2.#1. After receiving the STM32MP157F-DK2 board, I connected a 5V/3A Type-C Power Adapter to CN6 and verified Linux boot and operation. LCD operation.#2. Updated the Linux image on th...
Hello I am planning to use STM32mp257Fak3 with DDR3L (16bit and 32 bit saperately),can you suggest some DDR part no and it's sonnection.
Hello,I am working with an STM32MP151 and I would like to start the Cortex-M4 core as early as possible during the boot sequence.The main requirement is to run a real-time task on the M4 that reads an analog input (ANA0 – ADC channel) with minimal st...
Hello,Currently I'm working on a project that requires a synchronized clock signal between multiple devices connected through Ethernet.The logic solution for this is PTP, and using linuxptp I was able to archive synchronous PPS on PG8 pin between dev...
Hello!I am in the progress of setting up a Yocto based build for a custom board based on a STM32MP157C. I am using "vanilla" Yocto scarthgap with the respective ST meta layer: https://github.com/STMicroelectronics/meta-st-stm32mp meaning I created a ...
Hello, I am trying to load an .elf file on the M33 core on my stm32mp257f processor. When I launch the remote core using remoteproc I get the following errors. root@stm32mp257f-hydra-mx:~# echo -n /home/root > /sys/module/firmware_class/paramet...
Hi,I am trying to work with the USART6 which is connected to is connected to PF13 (TX) and PF14 (RX) on the extended GPIO.It looks like the SCRIF does not allow access to this USART, wven though the OPTEE configuration seems to enable it:from optee/....
I have a STM32MP257 custom board and I'm listening on UART6.When I boot, I get nothing. No messages or other text. I have not yet implemented any Linux onto my SD-card.The issue is that I have my USART6 boot pins on PF13 and PF14, instead of PF4 and ...
