Duo 256M - Mainline

Duo
1

Hello, I’ve had my milk-v duo for quite a while now and i was astonished by the pace mainline progress was going at, But it seems to have slowed down significantly now…

I was able to boot mainline on my duo 256m roughly last year using unmerged patches (at the time), However now i’m completely unable to boot it and it can’t seem to find the SD card (waiting for /dev/mmcblk0p2), This is mostly a device tree issue since if i use my dtb from last year it boots just fine…

That being said i would like to know why there’s no mainline branch nor mainline support in the SDK?
Even if things are still in development i feel like people should be able to boot and test the current state of the hardware?

Am I reading that rightly that you don’t have an SD card installed? The 256M requires it to boot.

There is a new development branch here:

Hopefully Zephyr OS will be officially supported soon. There are some people working on that.

Duo can boot off SPI flash. But on mainline (I tried 6.6) only SD card works.

No, I do have an SD card connected but on mainline it does not seem to detect the SD card, It does if i use slightly older device trees (with patches) before sd card support was merged into mainline.
