Firmware update 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.
