Hi @Eldam
I understand you intend to flash your Emmc from SDCard.
This topic has already been covered in following post :
https://community.st.com/s/question/0D50X0000BiBhHQSQ0/stm32mp153a-failed-to-boot-from-emmc
I copy here the most interesting part which is the detailed procedure
8. Prepare eMMC
===============
You can use U-Boot to copy binary in eMMC.
In the next example, you need to boot from SDCARD and the images (tf-a-stm32mp157c-ev1-trusted.stm32, u-boot-stm32mp157c-ev1-trusted.stm32)
are presents on SDCARD (mmc 0) in ext4 partition 4 (bootfs). From the starter package of EV1, you can simply copy the 2 binaries in “/boot�? directory of your board.
To boot from SDCard, select BootPinMode = 1 0 1 and reset.
Then you update the eMMC with the next U-Boot command :
a) prepare GPT on eMMC,
example with 4 partitions, bootfs, rootfs, userfs and vendorfs:
# setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=vendorfs,type=linux,size=16MiB;name=rootfs,type=linux,size=640MiB;name=userfs,type=linux,size=64MiB "
# gpt write mmc 1 ${emmc_part}
b) copy SPL on eMMC on first boot partition
(SPL max size is 256kB, with LBA 512, 0x200)
# ext4load mmc 0:4 0xC0000000 tf-a-stm32mp157c-ev1-trusted.stm32
# mmc dev 1
# mmc partconf 1 1 1 1
# mmc write ${fileaddr} 0 200
# mmc partconf 1 1 1 0
c) copy U-Boot in first GPT partition of eMMC
# ext4load mmc 0:4 0xC0000000 u-boot-stm32mp157c-ev1-trusted.stm32
# mmc dev 1
# part start mmc 1 1 partstart
# part size mmc 1 1 partsize
# mmc write ${fileaddr} ${partstart} ${filesize}
To boot from eMMC, select BootPinMode = 0 1 0 and reset.
Here is the boot result (I started from an empty emmc):
