It almost seems that you are not using the cross compiler. There are two ways to specify the cross compiler. 1. As part of the config: make ARCH=xtensa menuconfig and set General setup ---> (xtensa-linux-gnu-) Cross-compiler tool prefix 2. Provide with make: make ARCH=xtensa CROSS_COMPILE=xtensa-linux-gnu- Since you are not specifying CROSS_COMPILE, did you configure it in .config? -Chris > > (the attachment is the related .config file)
