How to enter DDR interactive mode by defining CONFIG_STM32MP1_DDR_INTERACTIVE ?

Arnas Celkys · ‎2021-12-14

I am using stm32MP157F-DK eval board (on windows) and I would like to try the DDR testing tool on cubeMX. But this is my first time trying to do so - I try to follow steps in "U-Boot SPL: DDR interactive mode" (url: https://wiki.st.com/stm32mpu/wiki/U-Boot_SPL:_DDR_int). It states i should define this mode under CONFIG_STM32MP1_DDR_INTERACTIVE - but I dont understand when or how should I do that? Should this be done on full flashlayout_st-image-*** or should i just have boot running?

**********************Summary of solved issues************************

Huge thanks to, @Kevin HUBER , for all the help. If anybody will face similar issues I will just layout all the summary I did that helped me out.

1.Setting Linux on dedicated hardware rather than just VM - solved the issue of mass-storage not appearing on PC (when using VM) after the ums 0 mmc 0
Updating Ubuntu to - 20.xx version solved the issue with SyntaxError: invalid syntax in SDcard population issues
Always after selecting SDK make sure TF-A is installed - this solved the make or Makefile.sdk.all errors.
Updating the boards current Flashlayout with trusted lates image from en.FLASH-stm32mp1-openstlinux-5-10-dunfell-mp1-21-11-17_tar_v3.1.0 - solved the missing FIP directory in U-boot interactive mode after command ums 0 mmc 0.

Following the information provided by @Kevin HUBER and these basic steps, i finally managed to access DDR interactive mode and do the the test on my custom board - and i am glad to say that ir passed all the tests :)

Hi,

Yes, but only if you have working a working U-Boot or Linux on your board....

How to manually update bootloaders - stm32mpu

Then you can use these commands to update the target with any downloaded files, for example with linux command "scp".
