Latest Ubuntu Desktop official images bootloop the R6S

[ayytee]

Today I downloaded the two latest Ubuntu desktop official images for my R6S:

rk3588-eflasher-ubuntu-noble-desktop-6.1-arm64-20250122.img.gz

and

rk3588-eflasher-ubuntu-noble-minimal-6.1-arm64-20250117.img.gz

After I flashed my R6S with the first image and rebooted without the microSD it went into a boot loop. I guessed there might be something wrong with the first one so I repeated the process with the second but, lo and behold, both had the same behavior.

Is there a trick to getting it to work or can someone else confirm the same behavior?

Cheers

The NanoPi R6S is likely boot looping because the eMMC still has a bad or incomplete image, so you need to properly reflash or erase it from a working microSD boot.

I’d try booting the R6S from a known working microSD image first, then completely erase and reflash the eMMC. A corrupted or incomplete eMMC installation can cause this kind of boot loop. After flashing, make sure the microSD is removed before rebooting. If the issue still happens with both official Ubuntu images, testing an older stable image would also help confirm whether it is image-specific.
