Documentation for Radxa Zero 3W

[sunishnet]

I got Radxa Zero 3W for experimenting aa-proxy, but don't find info on how to load the firmware and configure it. Be it eMMC or sdcard.
Is it not documented or it's just that it's not listed in the readme/home page.

You're right - it's not documented anywhere (possibly because Radxa support was only added fairly recently).

As for the process itself: the same image is used for both SD card flashing and eMMC installation.
So far, only one person on Discord has flashed it to eMMC, but from what I recall, it's the standard Rockchip procedure:
you boot the board with the maskrom button held down, the chip enters flashing mode, then you run the Rockchip flasher, etc.

If you'd like more details, feel free to hop on our Discord - it's the best source of up-to-date info at the moment.

If you're going to try this, use this image - it includes a few more recent fixes that will be part of the next release:

I am leaving this open to not forget about adding some documentation...

For flashing to SD card, use the same procedure as the RPIs. You just need to burn the image as-is to the SD card.
You can use dd on Linux or Balena Etcher on Windows.

For eMMC, you can follow this official Radxa guide
https://docs.radxa.com/en/zero/zero3/low-level-dev/install-os-on-emmc
Just flash the same image as before. There is no separate image for SD Cards and eMMC
