Oops I'm sorry,
all of the drivers are for SPI,
I have changed the driver which comes with eldk to compile with TQM850L.
this driver's header contains a #define statement for a specific module, and I have changed it. secondly I have changed the chip select statements.
Best regards, Yigit Can
PS : I attached another code that I use. I'm compiling this code with the kernel, it works with SCC1 enabled and it does not work with SCC2, SCC3 or with disabled SCC ethernet.

I use 3 different drivers,
Arrrgghh. Please don't let my guess what sort of drivers these are.
Ethernet? UART? HDLC? SPI? Or what?
I'm using standard TQ850L_config in kernel (eldk 2.0.2)
...which works fine.
first one comes with eldk I only made a small modification to compile
with
TQM850L.
OK, so what exactly did you change, and why?
second is an interrupt driven driver working with TQM862L (I have
verified
it)
and I wrote the last one using 850 user-manual to be sure.
All has the same problem when I choose SCC1 they work perfectly ,but
when I
choose the other SCCs or disable the SCC ethernet, they send data but they stall while receiving becouse the buffer
descriptor
cbd_sc register does not change (rx_bdf->cbd_sc).
You mentiones SPI before, but now you talk about using SCC1 - this makes no sense to me.
