Ethernet Problems on TQM8xxL boards
- I am using a TQM8xxL module on a STK8xxL Starter Kit board.
Everything is fine, but Ethernet does not work - neither in PPCBoot
nor in Linux.
- The TQM855L/M, TQM860L/M and TQM862L/M modules use SCC1
for the Ethernet interface.
Make sure that jumpers are set on connectors labeled X.12, X.13 and
X.14 on the STK8xxL board on the positions 1-3 and 2-4; also make
sure to remove the jumpers from positions 7-8, 9-10 and 11-12 on
For the TQM823L and TQM850L modules SCC2 is used for Ethernet. Here
jumpers must be set on connectors X.12, X.13 and X.14 on the
positions 3-5 and 4-6; X.30 is used for USB configuration on these
boards - if you don't use USB it's safe to remove the jumpers from
positions 7-8, 9-10 and 11-12 on X.30.
