- What I did
1. Nvram device exposed to user space.
- How I did it
1. Nvram 0x49 offset is used for last reboot reason. (Vendor Defined Offset)
COLD_RESET = 0xE # Cold Reset (offset value)
WARM_RESET = 0x6 # Warm Reset (offset value)
- How to verify it
1. Dump the Nvram content. (particularly check the 0x49 offset).
Command:- dd if=/dev/nvram of=nvram.dump
- Description for the changelog
