Unable to boot, EEPROM suspected to be modified

Hi everyone, I’m busy with Jetson nano unable to boot. I already know that the reason why I can’t boot is that there is a problem with EEPROM data.I found that the last byte of EEPROM data in all the abnormal modules was 0X80. But I don’t know what 0X80 means.Can anyone help me? Thanks a lot.
