| Yes, and those have more I/O pins exposed.

| Yes, it's nice. Good for making Linux based USB devices (based on
| gadget subsystem).
|
| It can run Arch Linux ARM if you enable swap on uSD card, and
| don't overdo it with your RSS. Systemd doesn't really support
| 64MiB RAM out of the box, though. It runs, but systemctl daemon-
| reload fails, eg.
|
| You can ignore systemd boot flow and run Arch Linux using busybox
| or other init process, so you get all the Arch software/pacman +
| low memory use of cheaper PID 0 process and startup scripts. :)
|
| The board runs best with pure statically compiled busybox running
| from initramfs. Boot times of the kernel are like 150ms because
| there's not really that much HW in the SoC or on the board to
| initialize. So you can plug the board into PC and you get USB
| device ready in ~2s.
|
| Fun tiny thing to eg. hide your secret material from your PC.
|
| I wrote a simple 8 KiB bootloader for RV1103/6 so that I don't
| have to mess with porting U-Boot to this, and made it run with
| Linux 6.10/11.

|
| Do you have that bootloader published someplace? I'd like to
| get a more recent kernel going...

| I have a kernel here

| Bootloader will be at https://xnux.eu/log/ when I get to
| releasing it.

| Pretty amazing that this has a video encoder in the chip:
