gullyg Posted May 7, 2017 Posted May 7, 2017 Hi, I have an Oracle PI PC+ which will not boot without the hdmi connected. If you disconnect the hdmi once the board has booted it crashes or at least stops responding to ping/ssh over the ethernet. I've used pretty much all the builds I can find on armbian.com including the nightly builds with don't show a display at all but still fail without the hdmi. I've also tried booting from SD card and the emmc almong will messing with the /boot config files such as setting the console to serial and can't see anything interesting in the messages file. It shouldn't be a power issue as I'm using an Anker 2.4a PSU but I've tried other PSUs as well with no luck. Thanks
martinayotte Posted May 7, 2017 Posted May 7, 2017 That is a bit strange ... I did my own build for OrangePiPCPlus 2 days ago, and this build is running fine on my 4 boards which are all headless. Did you attached an Debug USB-TTL to see what kind of errors occured ?
gullyg Posted May 7, 2017 Author Posted May 7, 2017 Hi thanks for your response. No unfortunately I don't have one - it's on order
Igor Posted May 7, 2017 Posted May 7, 2017 I am doing nasty thing on daily base particular to this board and I never experienced such problem.
gullyg Posted May 7, 2017 Author Posted May 7, 2017 So after a bit of scouting about I've managed to get the OTG port to act as a serial connection using https://oshlab.com/enable-g_serial-usb-otg-console-orange-pi-armbian/ But this doesn't work either when attempting to boot without hdmi suggesting the kernel isn't getting very far - neither is there any network activity lights. Searching the internet it appears there were some ripi boards suffering this at out point as a bug but updating the firmware sorted the issue... Unfortunately I seem to be "unique" with this issue. Hopefully getting serial off the gpio ports will help but I'm not feeling it.
