Vocore2 Recovery Through Boot Command Line

[rcpaul]

Does anyone know how to recover from the following, it won't let me select option "4" like I usually do, seems like its selecting option "3' on its own.

Connecting to /dev/tty.usbserial, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.

Please select 0 in uboot and upload the firmware again.

It doesn't allow me to choose 0

[Vonger]

Try this way, connect VoCore2 RESET to GND, then connect VoCore2 to power, open console.Then disconnect RESET to GND, it will boot from uboot.
