Welcome to Buildroot buildroot login:
The issue are due to a bad assembler generation by binutils tools with thumb code on kernel. There is two way to solver it: 1. use an old binutils tools 2.28 (see commit b3dddb0a787352bb836ce972e4f07b59d79068e7 package/binutils: default to 2.28 for Cortex-M targets) 2. use a more recent kernel which generate a correct assembler. I will try to provide a new kernel configuration.
