Hi Ming,
We're on leave for the Chinese New Year, could you try the following steps?
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
GCC_VERSION=7.5.0 make.cross ARCH=riscv
Best Regards,
Rong Chen
