Cannot flash Jetson Thor with jetpack7.0

we cannot flash the Jetson Thor with jetpack7.0 (L4T r38.2) on our custom board.
we don’t have EEPROM on our board. and I have modified the MB2 BCT file.

The flash command I used as follow: sudo ./l4t_initrd_flash.sh jetson-agx-thor-devkit internal
the flash log as follo

How to resolve this? would you please give me any suggestion?

check your UART serial log will and it might tell what is going on.

This is our uart debug log :

Can you help me find the problem? Thank you very much.

what change did you do in the file? It is still trying to read CVB EEPROM.
