[microblaze-uclinux] Xilinx EMAC sgDMA sending but not receiving

[Eric Bissonnette <eric.bissonnette@xxxxxxxxxxxxxxxxx>]

Hi, we are using petalinux-v0.20-rc3 and uClinux 2.4. I have the EMAC 
working fine in FIFO mode. But when I rebuild with  PARAMETER 
C_DMA_PRESENT to 3, I get the following:
eth0: using sgDMA mode.
eth0: Xilinx EMAC #0 at 0x40C00000 mapped to 0x40C00000, irq=1
eth0: id 2.0l; block id 11, type 1

Then if I try to ping a target, the board transmit and the target reply 
but nothing is received.

Any ideas?

Regards
