Hi, rv32 uclibc toolchain is based on gcc12.2, while rv64 uclibc is based on gcc13.2 I built them with the mainline buildroot, and rv32 toolchain was built a year ago, I forget whether there was patches applied. I may apply patches from your mini-rv32ima repo. The rv64 toolchain was built a month ago, no patch is applied.
