Hi, I m working on the Encore M3 board that has the AU1500 MIPS processor on it. I aim to port the 2.6 linux kernel to the board which is already supported in the 2.4 kernel. The start_kernel function in linux/init/main.c file, calls a function calibrate_delay found in the arch/frv/kernel/setup.c file. Why does the kernel call this function which is a part of the Fujitsu FR-V architecture? When I build the image, this is the point where the kernel is stuck and the last contents of the log buffer show the following printk message from the calibrate_delay function: > Calibrating delay loop... Thanks, Ashlesha.
