Forrest,

Can you elaborate on what this issue was:

•MCF5441X
◦Fixed multicast rx error

I'm doing a ton of multicast on the MOD5441x platform so just want to better understand what the issue was and the impact of the change so I can be aware of any impact it might have for me.

Thanks!
Scott

Related to MOD54417 switch table. MOD54415 is unaffected. Basically, the code to add the Multicast MACs was correct for adding the entries, but missed the fact that they should also add the processor to list of destinations (The code was lifted directly from the learning function of the switch, so the included ports was wrong). It is literally a 1-bit change (0x6 became 0x7).

In other words, for 54417 with multiple Ethernet interfaces, not an issue with single port 54415

I was just about to report the double minus sign for negative numbers issues when I saw the 2.7.5 release. Is this related to the underlying gcc version?

[sblair]

The underlying gcc version in 2.7.5 is the same it has been for quite a long time. I'm guessing the issue was related to reworking of the print libs from last year.

Entirely related to the libs. That said, a new GCC is coming...
