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 ...
I have built a custom board by using STM32MP257F and I want to boot on USART6. I have not succeed to boot on USART6 when I compile my own fsbla by change the device tree of TF-A.I got a suggestion from ST Dev team to run this ROM tracedump wiki-stm32...
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...
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...
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
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 ...
I installed the latest STM32CubeProgrammer in WSL on windows 11: the GUI has issue to load so I'm using the STM32_Programmer_CLI.However the flashing would fail most of the time:---- log output begin -----....Sector[0] downloaded successfully...File ...
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'm stalling with an issue with Optee on a custom board with 256 MB of ram and an STM32MP135D.The environment was working with the DK (MP135F and 512M ram).I followed the guide for the configuration with 256 MB of ram (https://wiki.st.com/stm32...
