4. Flash the MP
Refer to the general instructions in
Upgrading Mesh Potato Firmware HowTo
on the Village Telco
Wiki. Following is a brief description of the flashing process.
•
Connect the MP directly to your PC with an Ethernet cable with the MP power
off
•
Execute potato-flash:
$ sudo potato-flash eth0 openwrt-atheros-root-rv278.squashfs openwrt-atheros-vmlinux-
rv278.lzma
•
Wait for the program to start looking for the MP device - a series of dots will appear on the
screen.
•
Switch the power
on
to the MP.
•
Wait for the flashing process to complete and for the MP to fully restart.
This will take several minutes.
This is a good time to have a coffee.
•
Wait for three minutes after the MP WiFi led starts to flash to ensure that flash is complete.
