Thanks, Chris.However, the issue is actually the default gcc mode is an arm processor without umull. The kernel config should add:makeoptions CPUFLAGS="-march=armv4 -mtune=arm9"Or perhaps that should be in files.ep93xx. It would then benefit the whole kernel.I revise epclk.c and files.ep93xx, and Armadillo-9 worked.
Has it made any obvious performance differences? Never sure it an optimized cpuflags kernel helps dramatically or not.
Thanks, Chris
