To fix this kconfig problem, you can use: ./scripts/config --set-val ITCM_RAM_BASE 0xe0000000 or ./scripts/config --file csky-randconfig-c003-20210411 --set-val ITCM_RAM_BASE 0xe0000000 if you want to modify some file other than ".config". (0xe000000 is an arbitrary value here -- just cannot be 0xffffffff.) Then run "make oldconfig" and "make all" or however you normally build a kernel. It looks like the Kconfig file's ITCM_RAM_BASE parameter is expected to be set/modified by the user. The default value of 0xffffffff is invalid. -- ~Randy
