Unable to find the partition with the uuid mentioned in metadata

[ahamod3.1416]

Hello everyone,

we have developed a custom board based on stm32mp157 chip. We also forked the tf-a and u-boot from meta-st layer. If we flash an sd card using the flash layout, image works. But my goal is to copy the files from linux host machine, which I did. Now the image does not boot from the sd card. It is showing following error.

Does anyone have any idea, how to solve this? THANKS IN ADVANCE.

Hi,

UUID of the GPT partitions are used in TF-A to select the FIP partitions, these UUID information is used in "metadata" used of TFA secure udpate as decrivbe in https://wiki.st.com/stm32mpu/wiki/Secure_Firmware_Update

You need also to select the correct Type UID for FIP

See also https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#Block_device_GPT_partition-_SD_card_-2F_e-E2-80-A2MMC

The expected UUID for STM32MP1 board can be found in WIKI

https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#GPT_partuuid_of_FIP_partition

on Linux you can define the UID when you create the GPT partition, when you use gdisk:

on modify later for example with sgdisk

-t, --typecode=partnum:{hexcode|GUID}Change a single partition's type code. You enter the type code using either a two-byte hexadecimal number, as described earlier, or a fully-specified GUID value, such as EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.

-u, --partition-guid=partnum:guidSet the partition unique GUID for an individual partition. The GUID may be a complete GUID or 'R' to set a random GUID.

You can check also the script for example.
