Hi List,
I need to access an FSL port with my own hardware attached, but I'm not
sure how to do it correctly. I found the FSL driver by John but don't
know how to use it correctly. fslfifo.c says:
[...]
* Simple driver to provide Linux-style FIFO interface to custom hardware
* peripherals connected to Microblaze FSL ports. See Microblaze user manual
* for details of FSL architecture.
*
* read() and write() operate on software buffers, with a tasklet scheduled
* to actually stuff data into / out of FSL ports. This might be better
* served by interrupts, however the hardware doesn't support it yet.
[...]
So I guess, it works quite similar to usual file handling? Can anybody
give me with a short example or a link? I was not able to find any code
or documentation on the net (except for the Xilinx stuff only mentioning
low-level blocking access).
Thanks in advance
Cheers
/Chris
