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...

Good. I am trying to load the system to my stm32mp157c-dk2 using STM32CubeProgrammer software, but I get the same error when loading partition 13 every time. The error is as follows: Error: failed to download Segment[0] Error: failed to download the ...
Hello,We are designing a custom board with the "STM32MP157FAC1" MPU.Would it be possible to get the die to BGA package pin delays for the DDR3 and the EMMC interfaces ?The AN5122 seems to only have track lengths. Our PCB track layout has some constra...
I have a system (built using yocto kirkstone) working with the bootchain TF-a -> sp_min -> uboot when loaded from the sdcard and from the emmcI have tried to boot into uboot by loading it directly into memory (as a precondition to the use it to flash...
Hello @everyoneI have a OSD32MP1-BRK mpu board. I want to test maximum gpio toggle speed. Currently i used libgpio and using this code i achieved 4.1 us (microsecond) between rising and falling edge of pulses.This is too slow as per our requirement. ...
