But I do not understand well. When burn flash.bin into boot partition, SPL will be loaded from boot partition,
yes, correct. On my test board flash.bin is in the first boot partition and SPL is loaded as expected.
SPL will load container images from boot partition,
SPL switches to user partition during the inif of mmc driver: spl_mmc_load() -> mmc_init()
Then it tries to load the container image in spl_mmc_get_uboot_raw_sector(), but here it reads the data from user partition and the header is not recognized as a valid header.
but in your case, I think SPL will load container images from user partition, so you switch back to boot partition.
yes, because the mmc init switches to user partition.
From common/spl/spl_mmc.c, there is boot partition switch there, Why need to add such logic in imx8/image.c?
spl_mmc_load() reads the container header before partition switching.
