Manual Upgrade
Shark Jack firmware may be updated by using the sharkjack.sh helper script. That said, it is also possible to manually upgrade the firmware by following this process:
- 1.
- 2.Power on the Shark Jack in Arming Mode and connect it to a reliable USB power source
- 3.Copy the file upgrade file to the Shark Jack's /tmp directory via SCP (e.g. "
scp upgrade-1.1.0.bin [email protected]:/tmp/") - 4.SSH into the Shark Jack (e.g. "
ssh [email protected]") - 5.From the Shark Jack's bash prompt, issue the sysupgrade command relevant to your firmware update file (e.g. "
sysupgrade -n /tmp/upgrade-1.1.0.bin") - 6.Wait 5-10 minutes as the Shark Jack flashes the firmware and reboots.
DO NOT unplug the device from USB power during this process as doing so will render the device inoperable. This process will require 5-10 minutes. Powering off the Shark Jack at this time will result in damage to the device.
