We are running a stm32mp151c with stm32mp linux built with yocto. The kernel complain that the cpu0 clocl-frequency is not set, but the patch layers/meta-st/meta-st-stm32mp/recipes-kernel/linux/linux-stm32mp/5.10/5.10.116/0022-ARM-5.10.116-stm32mp1-r...
Hi guys,The schematics for STM32MP15x-EVAL board (MB1263) uses a level shifter for SDcard from NXP (IP4856CX25) that is now obsolete. I found 2 close alternatives:ST6G3244MEBJR from ST, with one pin only (C4) different from IP4856TXS0206YFPR from TI,...
I'm trying to get to know stm32mp1 while making a board for this thing.While using the default image provided by manufacturer seems to work. The kernel used is old compared to the current ST BSP and support from them isn't exactly great so I'm trying...
I'm trying to testing secure boot on a STM32MP157F-EV1. To do so, I planned to use the fuse override command to test secure boot without having to actually burn the OTP 24-31 with the public key hash.But it appears that fuse override command is not w...

I have the STM32MP157C-DK2, and I plan to make a user board.Before creating a user board, I have a question.1. I want to know how to debug Cortex-M4 firmware on the user board. GDB debug is used in No. 7 in the link below.https://wiki.st.com/stm32mpu...
Hello,I read the AN5122 which explains in chapter 4.2, that the RAM lane byte 0 must be connected to byte 0 of the MP1 and that the bits swapping is not possible. However on the EV1 board, the bits inside byte 0 lane are swapped. Furthermore, i do no...
Dear experts. we plan to use a STM32MP157, where the A7 core should have 512MB DDR RAM, and theM4 core 16 MB. What options exists, to give the M4 core that 16 MB of RAM?From the DS, i understand that the DDR RAM of the A7 is not accessible for the M...
Hi,We are using the meta-st-stm32mp layer in out Yocto build system. We have had the system run on the Dunfell distribution up until now with OPTEE as the secure OS.For Dunfell the version of OPTEE is 3.12 along with patches from ST, a we tried to up...
