Minor bugfixes.
Release notes:
- Fix deleting key from SD card (#164) (@EndNationStates)
- Disallow empty names for seeds and wallets (#165) (@stepansnigirev)
If you have firmware v1.4.0 or later you need to copy specter_upgrade_v1.5.6.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_v1.5.6.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.
You can get the public key here: https://stepansnigirev.com/ss-specter-release.asc.
It is also available via keys.gnupg.net or keys.openpgp.org.
