Hi everyone. I have a beaglebone black which is giving me constant display issues. The problem is as follows:
I installed the latest Debian Buster IoT with no GUI (AM3358 Debian 10.3 2020-04-06 4GB SD IoT) from BeagleBoard.org - latest-images following the instructions (use balena etcher to create SD card image, etc). It worked perfectly. I ran sudo apt update and installed the latest update, sudo apt full-upgrade, etc. Everything was absolutely fine - until I reboot the device.
On reboot, there is no display. I have tried absolutely everything I can think of including changing HDMI cables, rebooting, power on/off, and even re-doing the whole process. Again, the same thing happens - works fine first time, but when I shut down the BBB, there is no display when I power up again.
I am certain it is not anything to do with the HDMI cables, as everything works fine on first boot, the problem only comes after I shut down (no matter if I use sudo shutdown, sudo reboot or just pull the power), always there is no display on the second and following boot-ups after a new install.
So I also tried starting again and installing a different image - this time the AM3358 Debian 10.3 2020-04-06 4GB eMMC IoT Flasher image to do a flashed eMMC install. Again, the same thing - it works absolutely perfectly and I have a fully functioning BBB - until I turn it off. Turn it back on - nothing.
It’s very frustrating and I have now tried both firmware images a number of times with the same result - works fine first time, then never again. I am using the proper 5V cable and good quality HDMI cables etc. I’ve tried image install with both the USB and the 5V power cable, always works on first boot, but second time I boot after the initial set up, no display.
I know the BBB is still operational as I can SSH into it with a USB connection to my laptop. But I want to use the device with a display,
Any help or tips gratefully accepted. I hope I have made my issue clear, if not please accept my apologies, I am very much a newbie with beaglebone.
