Bugfixes and improvements.
If you have firmware v1.4.0 or later you need to copy specter_upgrade_v1.5.2.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_v1.5.2.bin
file to your board when it's connected over miniUSB.
IMPORTANT: If you want to use self-signed bootloader and firmware check out the instructions in the bootloader repo
