Booting Debian on SolidRun ClearFog CN9130 Base and CN9130 ClearFog CN9130 Pro

SolidRun provides different pre-baked images to get started with their ClearFog CN9130 devices. Most interesting is the Debian image, since it works with upstream kernels. The only real addition SolidRun made to the distribution are the device tree binaries, that have yet to find their way into mainline Linux.

Still, both devices aren't able to boot the image out of the box at the time of writing in mid July 2022.

Beginning with devices produced April 2022 or later, the units ship with a pre-programmed u-boot boot loader on the SPI flash. The devices are also selected to use this boot method and the boot loader is prepared to look on all other media for something bootable. This is convenient, since you can just plug in a microSD card and boot the thing, move the image onto the embedded eMMC and it will fallback
