I've only done a bit of Raspberry Pi stuff with openSUSE. I was happily surprised how much I could compile in it. Even if it was sooo slow.

I can highly recommend doing compilations on a system emulated with qemu or cross-compiling. I use qemu, it's dead-easy and a _lot_ faster. There is a how-to in the wiki, somewhere.

I was playing with things like installing things via zypper and keeping the system up-to-date. I think that if I was to use this in a product, the compilation would be as you say. This is how we build all our software. Perhaps not specifically qemu, but directly on our openSUSE build system. We were trying to see how quickly the device could respond to interrupts on some line. We made a kernel driver. Unfortunately, it could not keep up. We wanted to react to and take action on a ~32kHz pulse. In a kernel driver with no context switch, it seemed that we could detect pules at up to 20 kHz. After that they started to be missed. Then we lost steam on this device... -- Roger Oberholtzer

Hi, Thanks for all the messages, looking forward to contributing more. Once I have more updates I'll post them here or in #opensuse-arm (I'm avicenzi on freenode).

Hi,

I have the following boards around (that are not supported afaik) and I plan to test and add support to:

- NanoPC T4 - NanoPC T3 Plus - NanoPi M4B - NanoPi R2S - Nvidia Jetson Nano

T3 Plus is similar to T3, M4B is similar to M4 (no wifi, bt) and M4V2 (more ram), some are RK3399 based, Jetson is similar to Xavier.

I'll start with ARM EFI image, as some have eMMC, M2, one can flash the bootloader into the board and use another disc to boot. Nano will probably require a custom image, like other Nvidia boards.

If you have one of these boards and want to help, or if you are already working on support for some of these, or if you have any tips/ideas, feel free to contact me, so we work together.

Thanks for working to support those boards. I do not have those boards, but if you need help/guidance, feel free to join #opensuse-arm on IRC for a live chat. :) Or ask your questions here, on the mailing list. Cheers, Guillaume

Best,

Alex
