Hello. I'm writing firmware for a BF526 based device that has to operate
in very low power mode for extended periods of time. Prototypes
typically sleep for ~30s, keeping code in SDRAM in self-refresh mode,
wake for a few seconds to do the necessary processing, then return to
sleep. With existing code we can restore operations in 60-100ms.
Is anyone aware of any techniques (hacks?) that would allow uClinux to
be restored in similar time-frames? Or what reasonable time frames might
be for uClinux?
Any help greatly appreciated.
