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?
Hello,I am in process of designing my own STM32MP1 powered device. I was wondering if I can use STLINK-V3MODS as a drop in replacement for ST-LINK/V2-1 in STM32MP157-EVAL reference design. I need the Virtual COM interface embedded in device.-Mark
I want to emulate the stm32mp157 on qemu. I have been taking the kernel image and initrd from yocto build, but it is not loading the kernel. using the following commandqemu-system-arm \-M virt -smp 8,sockets=1,cores=4,threads=2 -m 4G \-cpu cortex-a7 ...
Hello,I would like to ask you few questions since I have some unclearances about STM32MP157F MPU:1. If 933MHz DDR3L RAM was connected to the MPU according to the schematic, will the MPU automatically underclock it to max 533MHz?2. Is it possible to c...
