#816 closed defect (fixed)

mpc8xx ethernet struct has taddr members in the wrong order

Cc: bugs@… Blocked By:


The struct which describes SCC Ethernet mode parameters (m8xxSCCENparms_t) doesn't match the hardware: members taddr_h and taddr_l are transposed. When loading new multicast group addresses into the hash table, the wrong hash bit is set.


All MPC8xx BSPs

Write a group address to the taddr_* registers, and then issue the SET GROUP ADDRESS command. The wrong bit in the group hash table gets set, so the group address will not be recognized when multicast packets are received.
