Reset flags: 0x00000800 (hard)
Chip: g cr50 B2
RO keyid: 0x3716ee6b(dev)
RW keyid: 0xb93d6539(dev)
DEV_ID: 0x017950ab 0x04656742
>
Send the raw command bytes from the Reef AP, observe the result:
# /tmp/trunks_send --raw 80 01 00 00 00 0C 20 00 00 00 00 12
80010000001C0000000000123716EE6BB93D6539017950AB04656742
