I use 3 different drivers,
I'm using standard TQ850L_config in kernel (eldk 2.0.2)
first one comes with eldk I only made a small modification to compile with TQM850L.
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).
Best regards,

Yes, I attach an oscilloscope and I can see it sends the data properly
in addition to this problem, the drivers ONLY work with SCC1, choosing the other SCCs or disabling

SCC ethernet makes no difference.
I lost you here. Which driver work only with SCC1?
We have been using the SPI driver in several projects on different hardware, and did not notice any problems.
Did you check for possible conflicts in the usage of port pins?
