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 the SCC ethernet makes no difference.

If you cannot receive data it is _obviously_ a bug. The question is _where_ the bug is.
but when I use the SPI driver with Tqm850L (configured as SCC2 by default ) it does not receive any byte. The problem i found is the
SCC
Are you sure your SPI device is actually sending data? Can you see the data on the wire when you attach a LA / oscilloscope?
