We have number of reTerminal, and on one the front-buttons do not work. The issue persists across various OS and all devices are configured identically.
I have a dependency on the front hardware buttons, so I’ve stuck with the previous 2021-09-13-Raspbian-reTerminal.img OS image. They work in this image.
However, reTerminal Raspbian images beyond this do not have have the GPIO keys enabled for whatever reason. I haven’t had the time to do this, but you could decompile the dt overlay blobs from the working and non-working OS images and do a diff as a starting point for troubleshooting.
Until Seeed fixes the issue in the latest OS release, I’m going to stick to the 2021-09-13-Raspbian-reTerminal.img image as it works in that release.
Observation with 2021-09-13-Raspbian-reTerminal.img
However, as mentioned in my first message, all our reTerminal work just fine (gpio_keys recognized) across various OS (Raspbian, PantherX). It’s just this one reTerminal that does not work, no matter which OS or configuration I try.
Almost like a hardware fault, but I don’t think so.
It’s definitely not a hardware fault, it’s some kind of configuration issue - the same unit that has working gpio-keys, will fail to work when using a more recent Raspbian reTerminal image.
