Release notes:
- Allow export xpubs to SD card
- Add separate settings for every communication channel ( enable / disable USB, QR scanner and SD card )
- Add sound, aim and flashlight settings for QR scanner
- Fix a bug when parsing non_witness_utxo in psbt that actually has witness (hello Sparrow...)
IMPORTANT! This update will reset your USB settings to disabled. If you use USB you need to enable it from device settings.
If you have firmware v1.4.0 or later you need to copy specter_upgrade_v1.5.3.bin to the SD card and insert it into the device. The bootloader will check the signatures of the upgrade file and update firmware.
If your discovery board is empty or you have very old firmware (below 1.4.0) - just copy-paste initial_firmware_v1.5.3.bin file to your board when it's connected over miniUSB.
If you want to use self-signed bootloader and firmware check out the instructions in the bootloader repo
sha256.signed.txt file contains sha256 hashes of the firmware binary files and signed with @stepansnigirev's GPG key.
