I have a new Raspberry Pi with Raspian Wheezy installed and has several cables connected to it via the GPIO pins. However, I noticed if I have anything connected to them during boot up, the device fails to boot, and prints:
sh: can't access tty: job control turned off / #
If I disconnect the cables from the GPIO and power on, the device boots just fine, and I can use the GPIO pins. However, I would like the device to be able to do a complete reboot without me having to manually disconnect the GPIO every time it is starting up.
Is there some why I can leave the GPIO cable and it communicating device connected while it performs a boot?
Here is some discussion for the Raspberry Pi forms: http://www.raspberrypi.org/forums/viewtopic.php?t=60412&p=451108
Thank you for your time.
