Firmware update

The firmware can be updated using a standard Micro SD card.  The card must be formatted with FAT filesystem, and in the root folder it should contain two files:

  • jvs2jamma.bin
  • irkenlab.lic

The .lic file is the license file you received when buying the Jammafier, and is specific for each serial#.  This is to discourage cloning of the hardware.  Should you loose the .lic file, just send me an email with your serial number and I will provide a new one.

Update procedure

  • Power off cabinet
  • insert SD card
  • Power on cabinet
  • The device will now update itself, progress is shown on the OLED
  • When done, OLED will say "FINISHED - POWER DOWN"
  • Power down cabinet, remove SD card.
