Board ID Info

The board ID info can be stored on the tm4c internal EEPROM. We are using Block 1 (0x40-0x80). The ID information is stored in the following format:
| 2 bytes | 2 bytes | N/A |
|---|---|---|
| Serial Number | Revision # | Other |
"Other" will likely include information about the firefly configuration of each board, and any other information necessary.
Block 1 is password-protected so that the ID information is not accidentally rewritten. To set the password protection on a new board, use the CLI command set_id_password, which automatically sets the password as 0x12345678. To write to this block, use the CLI command set_id <password> <addr> <data>. To view the ID information, use the CLI command id.
