I’m new to Balena and working on my first diy project (having previously built a project from a blog).
For some context, I’m using a PI3A+, OS 2.43.0 and an adafruit GPS hat (which connects via serial interface).
Essentially, I cannot get the Dev version of 2.43.0 to boot when the hat is fitted to the Pi… In fact its slightly worse than that, even if you remove the hat the OS still wont boot and requires the SD card to be recreated!
I don’t have any issue with the production version of 2.43.0 - that happily boots with the hat installed.
I first thought it may be the console serial output (as I read elsewhere the dev build comes with this activated - unlike the prod one), however, I disabled it by making the root fs read/write and editing the cmdline.txt - Still no good.
With the hat installed and the SD loaded with the dev OS release - I get no output on the tty when observed via the hdmi port and the green activity led just blinks a couple of times.
What could I be doing wrong???!
