Pogoplug v4 - Automatic boot with Serial attached

Hello,

I noticed that when I have my serial/UART connection plugged into Pogoplug, it will halt at the uBoot "PogoV4>" prompt, but if I don't have the serial connection plugged in, it will continue correctly and boot Debian from my USB drive.

Is there a uBoot configuration setting that will tell the uboot to continue even when the serial connection is detected? I have a bootdelay set at 10 seconds, but not sure why that isn't applied when the serial connection is detected.

Thanks

That's strange. It should not happen unless you press a key on the keyboard. It might be something peculiar about your serial console. I've never seen this with my serial module converter and the Pogo V4.

Does the output look different between the 2 scenarios?

@bodhi, thanks for the reply and confirmation that this isn't normal.

Maybe it something funky with the USB TTY Serial Adapter I'm using or maybe it's related to SCREEN connection.

I think it is probably SCREEN. I use picocom only.

You were right, it was SCREEN (or maybe the connection string I was using).


SCREEN command I was using: screen /dev/ttyUSB0 115200 cs8 -cstopb -parenb

PICOCOM command: picocom -b 115200 /dev/ttyUSB0

Now I'm getting the countdown like I expected using picocom. Thanks @Bodhi.
