# OTP format:
# - OTP format version (0xFE: version 1)
# - vendor ID (01: ODrive Robotics - do not use this on custom incompatible hardware!)
# - product ID (01: ODrive)
# - hardware major version
# - hardware minor version
# - hardware variant (00: 24V, 01: 48V)
# Bits in the OTP can only ever be set to 0 but never back to 1.
# Therefore do not try to run this on the same board twice with different data.
#
# This OpenOCD command is intended for a STM32F405 and does the following:
# FLASH_KEYR = 0x45670123; // unlock FLASH_CR
# FLASH_KEYR = 0xCDEF89AB; // unlock FLASH_CR
# FLASH_CR = (1 << FLASH_CR_PG); // unlock flash memory
# [write OTP]
