Correct me if i’m wrong, but shouldn’t AT91C_LENGTH_FRAME for TxDescriptor be different than AT91C_LENGTH_FRAME_RX for RxDescriptor in SAM7_EMAC.c ?

reading the AT91SAM7X specs, Table 38-1 mentions RxDescriptor "Length of frame" field to be 11:0 thats 0x0fff and not 0x07ff

while Table 38-2 mentions RxDescriptor “Length of frame” field to be 10:0 that’s what should be 0x07ff

we would define 
AT91C_LENGTH_FRAME_TX 0x07ff
AT91C_LENGTH_FRAME_RX 0x0fff

there are only a couple of lines to be changed there after in SAM7_EMAC.c

am i correct?

This has come up before.  I cannot remember what the conclusion was.  I also cannot search the forum to find the thread, I just get permission denied message.

Are you able to search the forum?  If so can you post a link to what you find.

Sorry to miss this guys.  I have corrected it within Subversion and added it to the known issues list.
