Header is generated with
./tools/build_vendorheader 'key1,key2,key3' 2 1.1 SatoshiLabs assets/satoshilabs.png micropython/firmware/vendorheader.bin
where
- keyN is a 64 character hex string encoding the public key
- 2 encodes 2/3 key scheme
- 1.1 is the version number (major, minor)
- SatoshiLabs is the vendor name
- satoshilabs.png is the vendor image
Updated the firmware compilation that it adds vendor header and updated loader
that it handles vendor header to be present.
