RISC OS

Hi,

Has anyone managed to get RISC OS running on the Pinebook?

Thanks,

Ben

Hi Ben,
I have been working on a port of RISC OS Open to the Allwinner H3 for quite a while. I actually came over to this forum to try to find out what's going on with the status of the Pinebooks. My work has slowed down to a crawl because of the difficulty of accessing my hardware for working on the port. Time at my desk is very rare. I wanted to get my hands on a Pinebook for both developing on via the RO for Linux version which I can say works on an AW H5, and for developing for, once I work out how to boot into aarch32 SVC mode from U-Boot.

Most of the Allwinner SoCs have so much in common that once the CPU is in the right mode, it should work on pretty much any of the family. It may require some detection to locate the BROM, SRAM etc. but it's no big deal.

I haven't uploaded new code for a while to my GitHub repo, but I have been working on it. A first post with a link probably wouldn't go too well, so just look for the repo username "experimentech" on there.
Not that it'd be any use to anyone here unless they had something with an H3 and a serial port kicking around, I uploaded a fresh uImage to there just now.

I can see absolutely no reason why RISC OS wouldn't run on an aarch64 Allwinner SoC. Most of the hardware is very straightforward and pretty much copypasted from the reference designs.
