An example bootloader using the 16-bit MCC bootloader and the CAN or CAN-FD peripheral on the dsPIC33 Touch CAN LIN Curiosity Development board demonstrating the following:
- Immutable secure boot via CodeGuard
- A/B type bootloading with Flash partitioning to support two firmware images and anti-roll back
- Secure boot authentication via ECDSA signature verification
- Secure firmware update via CAN-FD
- Crypto acceleration via TA100
- (Optional) Permanent flash memory locking via ICSP inhibit
See secure_boot_and_secure_firmware_upgrade_over_canfd and the associated README.md files for details on the required hardware, software, setup, and how to run the demo.
