Hello,I would like to setup environment for STM32MPU according this instruction:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDKso I downloaded the SDK .tarhttps://...
I am familiar with the STM32 MCU:s and now I try to learn some around the Linux MPU:s.I am looking for a simple pheripheral application example on how to control e.g some GPIO:s from inside Linux using the STM32CubeMX and STM32CubeIDE.Any hints?Thank...
I am using the STM32MP157x-DK2 discovery board and building the qt-example image.During boot the ST splash screen is displayed on the LCD as things get underway. I replaced the .bmp with one of my own , horizontally oriented, and it was presented por...
Hi,I have working on STM32MP157C-DK2 Board and after application of 8KV ESD strike on USB Shield, the DSI Screen Goes off completely (Discharging on Ground only). To verify the issue I have applied the same strike on a custom board consisting of STM3...
Hi,I have an stm32mp157d-dk1 board, for which I am building the core-image-minimal image within the poky (Dunfell) distribution. Other than adding the "meta-st-stm32mp" layer I have not made any ST related customisations.I am trying to launch a custo...
HelloIn the new version of Yocto release mickedore, SIGN_TOOL variable needs to be specified to sign TF-A binary which should corresponds to STM32CubeProgrammer signing tool https://wiki.st.com/stm32mpu/wiki/Signing_toolPractically, how can we set th...
Hi,I bought two same board and use one to test.After upgrade stlinux on this testing board, the cpu it can recognize is only one when the other one can recognize it two.could you give me a guide to fix it and why this happened?Thanks.
I have a custom board with a stm32mp151c and 256M DRAM.Trying to get optee 3.12 from ecosystem 3.0.0 to start.Everything works fine with tf-a 2.4-r1 and sp_min, u-boot 2020.10 etc.But I can't get optee to start. I've enabled a high loglevel and the l...
When porting applications from single core M4's equipped with FLASH, the RAM associated with M4 in MP1 is supposed to cater for both RAM and former FLASH needs. It won't fit. How to overcome this if M4 code/data size cannot be reduced?
