Milk-V Mars

[crazyquark]

Hello,

 

I would like to add support for Milk-V Mars in the Armbian build system. Right now I am building for visionfive2(build boots fine with u-boot in spi) and intend to see if I can reuse the DTBs produced by the Milk-V Mars official SDK build(https://github.com/milkv-mars/mars-buildroot-sdk/releases/). I am looking for guidance on how to proceed. The board has the same SoC as the Visionfive2 but different peripherals (USB, m.2).

 

L.E. I realized that the bootloader from the image cannot boot the image, the “official “ u-boot from SPI flash is used instead. Possibly due to some incompatible config.

Started work here: https://github.com/crazyquark/armbian-build
I forked the kernel source from the official Mars repo(split off only kernel sources). Will be building an image and testing it in my Mars board.

Armbian Lichee Pi 4A image has Meles DTB in the boot partition :)

This is common. Sometimes other (similar or identical) board's DT is used and we always bundle more DTs in the package.

FYI, I've updated the fork, now I am using `starfive-linux` for the kernel(currently 6.14) instead of the old one provided by MilkV. There is also some (maybe minimal) support for Mars in the mainline kernel. I  need to look into the GPU driver.

The board boots, I do not know yet about HDMI output and other features but I am testing.

 

`uname -a` says:
