Hi, try this: http://www.gumstix.net/wiki/index.php?title=Kernel_Reconfiguration Change (with menuconfig) CONFIG_HZ from 100 to 1000, then you should get a higher timer resolution. I hope this is what you were looking for. best regards Sandra > Hi, > > I'm using a verdex motherboard and I need change my linux interrupt > frequency from 100hz to 1000hz in order to speed up my data transfer.
