That's not entirely unusual on this class of machine. At least it looks easy enough to solder and I guess you could probably run some jumper cables via the antenna hole. If you can't or don't want to solder it yourself then I bet if you take the board and some pin strip to a small mobile phone repair shop they'd be able to do it for you. > I have then try to boot OpenBSD on a radxa rock pi 5b.

That looks like the port has changed speed. I would first try 1500000 as it's fairly common on the embedded ARM boards. -- Please keep replies on the mailing list.
