Re: [microblaze-uclinux] Xilinx EMAC sgDMA sending but not receiving
Hi Eric,
I have fixed the SGDMA mode support for the opb_ethernet driver for both
the 2.4 and 2.6 kernel. This is going to be in the petalinux-v0.30 release.
There are some performance issues with the SGDMA mode that is also fixed.
The full fix touches quite a few places hence it is clumsy to send as
patch. But if you want I can send you the base patch to get it working.
Cheers,
Benny

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
