Stable AOSP version for db845c

Hello, can anyone point me to binaries for (or instructions to build) a stable (Android >=10) AOSP version for the db845c?

It may just be for my lack of experience but my experience trying to use the db845c with AOSP has been rough.

  • Pre-built options with Android Flash Utility and Linaro builds have been hit or miss, with some builds not even booting properly
  • I have tried building my own userspace and kernel according to the google tutorial but didn’t manage to build a working version.
  • My best attempt so far has been using android flash tool with build no 7980534, which works but has some unstable performance under the workloads I an using and I can’t tell why.

Any help is appreciated!
