1 year ago Hey @Cpasjuste ,
Yes, I got the pocket2 android kernel source from Retroid, and there is a UART port on the device. I can't remember what it is, but Thor from Retro Handhelds can likely help you more with setting that up. I was able to successfully boot PostmarketOS and an Ubuntu arm rootfs, but both had the same problem:
- no graphics acceleration
- display worked, but due to a quirk of the fpga of this device, it gives the OS a 640x800 screen buffer, but in reality the screen is 640x480. In Android, this is easily worked around, but I haven't figured out a way around it on Linux Distros. That's why I stopped working on it Ubports also booted, but had the same display problem.
I also attempted to get a 5.10 kernel working. It got to outputting in UART and pstore. If I were to get the display working, though, it probably would have the same problem. Here's that repo turtleletortue/pocket2_upstream_linux.
Overall, I gave up on it because of the display issue and the weak chip the device has. There's a chance you could have better luck, but know that you'd probably have to mess with display driver in order to fix the problem first. Let me know if you have any more questions.
Hi @turtleletortue,
First forgive me to contact you with an issue, but i'm not sure how to get in touch with you...
I will receive a "retroid pocket 2" in the next few days, and i'm planning to see how far i can go to port/boot a (non-android) linux on this device (yes, i know this will not be an easy task, but i'v already done this in the past on different devices). It's why i have a few questions:
Thanks in advance, cpasjuste
