I'm trying to keep nommu xtensa alive. > I see that buildroot has obvious blackfin (bfin), m68k, and xtensa > uclinux support.

E.g. the following configuration may be used to build uclinux xtensa toolchain for the dc233c core: https://git.buildroot.net/buildroot/tree/configs/qemu_xtensa_lx60_nommu_defconfig Also bFLT executable format is currently not supported for linux-user xtensa QEMU. The following branch adds that support: https://github.com/OSLL/qemu-xtensa/commits/xtensa-bflt qemu-xtensa built from this QEMU then may be registered as a binfmt handler for bFLT executable images allowing to run gcc tests that want to run target binaries. -- Thanks. -- Max
