STM32MP135F eMMC boot partition
Hello,
I am using a STM32MP135F on a custom board which is working well using SD Card (sdmmc1).
The SDCard is partitioned as:
1) fsbl1
2) fsbl2
3) fip
4) bootfs
5) rootfs
From the SDcard system, I try to prepare the eMMC (4GB, sdmmc2).
I tried different configurations:
- mmcblk1p1boot0 (and boot1) contains fsbl1 (tf-a*.stm32), mmcblk1p1 contains fip => Could NOT find the fip partition! (although it contains the right GUID for fip partition 19...)
- mmcblk1p1boot0 contains fsbl1 (tf-a*.stm32) and fip (at offset 256KB => dd seek=512 bs=512) with
VERBOSE: Failed to access image id=3 (-2)
ERROR: Failed to parse partition with image id = 3
ERROR: Could NOT find the fip partition!
STM32MP> mmc partconf 1
EXT_CSD[179], PARTITION_CONFIG:
BOOT_ACK: 0x1
BOOT_PARTITION_ENABLE: 0x1 (boot0)
PARTITION_ACCESS: 0x0 (user)The BOOT_ACK is often erase and I have to renable it manually via u-boot on SDCard.
When I read back boot0 and boot1 at offset, the expected magic is present. Do you have an eMMC mapping for simple boot (the update & secure boot will be implemented later) to boot from eMMC successfully?
For information, please find the arguments for TFA:
