Hi Thomas, Sorry that you had to spend so much time on it. There are currently the following restrictions: Only linuxthreads/old and no-threads is supported for Xtensa. There actually is a port for NPTL, and I'm trying to get it, but might take some time. I will update the patch to disable NTPL on linuxthreads for Xtensa for now. uClibc 0.9.33 doesn't have the required Xtensa patches, so you would have to select snapshot. I'm not sure what the best approach is here. Provide a 'back-port' patch with these patches for 0.9.33 or only enable 'snapshot' for Xtensa. I'll update the two patches to only allow to select snapshot for now. Note that uClibc has added a new config and the current patch that is in buildroot (uClibc.snapshot.linuxthreads-errno-fix.patch) doesn't apply anymore. I noticed that a similar patch was dropped for 0.9.33.2, so I was just also removing this patch for snapshot. I believe you created that patch, so do you know if it can be removed? I can provide a patch for buildroot to fix uClibc snapshot.

I don't think gcc/uclibc/binutils have upstream the needed code to build a Blackfin toolchain. We could certainly point Buildroot to the Blackfin specific gcc/uclibc/binutils repositories, if someone has a usage for the internal backend on Blackfin. Thomas
