Thanks for reporting. With the provided nommu config, I reproduced above compiling error and fix it with below change. I will merge it to the xtensa patch in v4 post. ===== In , the io memory mapping funcions should be wrapped inside CONFIG_MMU ifdeffery scope. Otherwise it will cause compiling error when nommu is enabled.
