I've been stopped dead by a limitation with the ARM-9 250 MHz SBCs, running Linux, that I've been relying on for my next project. The maximum rate I can run a repeat timer (setitimer, etc) at is 50Hz, ie. 20000 uS repeat time. If I set the repeat rate any faster the thing still repeats every 20mS. Is this a standard 'feature' of Linux SBCs? Does anyone run an SBC that will do significantl...

Maybe this question should be posted in a linux development group, however the use of a serial port is more typical in an embedded environment, so I try to post here. I have an embedded Linux box (based on a Raspberry) with a serial port converted to a USB port through a UART-USB transceiver from Microchip. This USB port is seen as a COM port under Windows OS.

The AT91SAM9260 appears to include EBI support for CompactFlash, but the AT91SAM9260-EK development board does not include a CompactFlash interface. Assuming I can come up with the hardware, how hard will it be to develop the U-Boot and Linux driver support required to boot Linux 2.6 from CompactFlash on the AT91SAM9260? Is this driver code already out there somewhere? Thanks. Jim ...
