Unable to get expected output while booting from emmc

kenizgandhi — Tue, 25 May 2021 05:53:14 GMT

I unknowingly clean he board as I was facing some error. So due to which when I try to follow the get started module and try to boot from emmc(0010), I am getting the below output. I want to revoke the initial files and settings of the board and I am expecting output as shown in Get Started (boot from emmc module 1) inorder to enter Linux. Can you please help me do it.

Board name : i.MX8M plus

Output:
