p1010 localbus hardconnet such as:cs1--norflash ;cs2--nandflash; cs3--cpld
I find cpu dead when I operation of three peripherals at the same time in diffrent task (in linux), I want to know if the driver needs mutual protection? but norflash nandflash are linux itself drvier.

I wonder if there's a design flaws with localbus ?
