[Efi332] Standard GNU C library for CYGWIN

[bowtievette at aol.com]

I'm interested in that Doug, as I've had plenty of trouble with the QSCI already. I just can't seem to get it to work as advertised and according the traffic on the Freescale list, several others have had trouble too.

I don't know if it'll help you or not, but I've written an ISR in assembly (currently untested) that uses the QSCI, and a pair of circular buffers to feed it--this allows the ISR to keep feeding the transmit queue and pulling data off the receive queue without intervention by the main program. 
 
Let me know if you're interested,
