Re: PiRLP Suddenly Not Working
David Cameron - IRLP
Something is dragging either the 5v or 3.3v rail on the pi towards ground.toggle quoted messageShow quoted text
Are you sure you are orienting the red line on the gpio cable onto the pi correctly?
Also have you checked the gpio db25 connector for broken wires?
When the pi is running, check the voltage to the 3.3v jumper.
Hope someone can help me with this. Have an IRLP board pre-modded to run on 3.3v coming off a Raspberry Pi 2 (wired only). Finally got it hooked up and working earlier but after firing it up a second time, Pi will not boot with the PiRLP board connected. Disconnect ribbon cable, Pi boots fine. Re-connect, nothing. Disconnected 3.3v jumper on PiRLP board and Pi boots fine, presumably because it is not getting power. Ribbon cables are connected correctly and this was working (one time) before bringing it home to power on again. Any help would be appreciated.
