Firmware update errors /problems
Message: Blank screen on startup
Cause: You're probably touching some of the components on the PCB
Fix: Disconnect, take care to not touch anything but the buttons and try again.
Message: card bad/missing
Cause: There is no card inserted, or the card is not accessible on the electrical level by the JVS-PAC 2.
Fix/Solution: Try another card.
Message: card format error
Cause: The file system is not readable by the JVS-PAC 2.
Fix/Solution: Verify that the card has a FAT filesystem on it. The JVS-PAC 2 is not picky about which FAT version (FAT32/exFAT etc), or computer system used to prepare the card.
Message: fw file missing / sha file missing
Cause: The firmware .bin or .sha file is not found.
Fix/Solution: Verify that the firmware file is extracted and located in the root directory of the sd-card.
Message: fw read error / sha read error
Cause: An error occured while reading the firmware files, most likely a dodgy card.
Fix/Solution: Reformat the card, then try a different card.
