Hi AllI am working on an AU1100 board (Aurora) from DSP Design and want to control the processor cpu speed, as in CPU_FREQ, type control. I suspect I am missing something somewhere, but I can't find any references to cpu speed control for the MIPS processors, specically the au1x range.Any clues?
I assume you mean dynamically? Or at boot time only?There is an Au1x power management implementation that I haven't tested in a while. It allows you to scale the frequency using sysctl, if I remember correctly.
