piejam Touch Display 2 support

Apparently Raspberry Touch Display 2 is not supported, at least it doesn't boot for me. I mean this one: https://www.raspberrypi.com/documentation/accessories/touch-display-2.html#specifications

Would it be a lot of work to add support for it? I can help, with some guidance...

That's right, I've been working with the V1 so far. I don't have V2 yet. But I'll definitely try to make it work. I'm currently working on the next release, I will try to get it in. May I ask which raspi version you have?

I'm using RP 4B.

FWIW piejam.log is empty after waiting a few minutes, but that might be because I have no way to shut the system down gracefully. (I don't have a serial-usb adapter at hand, will get to the serial console next week when I get one, assuming it's available?)

There are no drivers for touchdisplay V2 in the kernel, therefore you won't see anything. You can use a mouse and hdmi display in the meantime.

I have now a touchdisplay V2. I will start on support then. But only for pi4/5 for now. Release will come soon.

Release is out: https://github.com/nooploop/piejam_os/releases/tag/v0.11.0

Sadly i noticed a small issue in the last minute. Cascaded menus are a bit buggy when the screen rotation is used, which you probably want to use with V2 display, because it's in portrait mode by default.

The display is now working ok, not sure what's the menu issue is, yet, but then I guess it's not a big deal :)
