This is a POC to generate a valid DFU package to be flashed for the https://github.com/acalatrava/openhaystack_moko project. This POC uses fixed values for the initPacket
. So if the original firmware binary changes the initPacket
won't be valid. This should be addressed by using protobuf to generate a valid initPacket
.
First you need to copy the private key from the accessory in OpenHaystack by right-click on it and selecting Copy private key B64
.
The parameters needed are the DFU private.key
, the original firmware.bin
and the accessory base64 private key
.
❯ npm run signer -- --mode sign --privateKey ../private.key --firmwarePath ../firmware.bin --base64Key vedQnEUGLzEkVfSfqLaxobA+RihvVbFsrgQjzQ==
DFU Package generated successfully to ./dfu.zip
The generated dfu.zip
file should be a valid package to be flashed. (NOT TESTED)
You can verify if a ZIP file is valid by issuing the following command:
❯ npm run signer -- --mode verify --privateKey ../private.key --dfuPackage dfu.zip
[OK] Firmware Hash verified
[OK] Signature verified
