As for me - no, not until the end of this week.. I am puzzled with the following: I've got ML405 recently. There is a prebuilt bitstream with TEMAC in SGDMA mode for this board made by Xilinx (XAPP941). With the TEMAC driver from EDK 9.1SP2 and the XAPP941 bitstream I've got (no jumbo frames): XTemac: using sgDMA mode. XTemac: using TxDRE mode XTemac: using RxDRE mode XTemac: buffer descriptor size: 32768 (0x8000) XTemac: (buffer_descriptor_init) phy: 0x3cf8000, virt: 0xff100000, size: 0x8000 eth%d: XTemac: PHY detected at address 7. eth0: Xilinx TEMAC #0 at 0x80000000 mapped to 0xC5060000, irq=0 eth0: XTemac id 1.0f, block id 5, type 8 <snip> eth0: XTemac: Options: 0xb8f2 eth0: XTemac: We renegotiated the speed to: 1000 eth0: XTemac: speed set to 1000Mb/s eth0: XTemac: Send Threshold = 16, Receive Threshold = 2 eth0: XTemac: Send Wait bound = 1, Receive Wait bound = 1 <snip> [EMAIL PROTECTED]:~/netperf-2.4.1/src# ./netperf -l 30 -H 192.168.119.1 -i 10, 2 -I 99,10 -t UDP_STREAM -- -m 32768 -s 262144 UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.11 9.1 (192.168.119.1) port 0 AF_INET : ±5.0% @ 99% conf.

With xps (EDK 9.1 without any SPs) I've tried creating exact the same design. So that exact the same kernel etc could be used for the both bitstreams. And with the self-made one I see exact the same output with the only difference: [EMAIL PROTECTED]:~/netperf-2.4.1/src# ./netperf -l 30 -H 192.168.119.1 -i 10, 2 -I 99,10 -t UDP_STREAM -- -m 32768 -s 262144 UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.11 9.1 (192.168.119.1) port 0 AF_INET : ±5.0% @ 99% conf.

I also pulled the additional timing constraints from XAPP941's data/system.ucf into the self-made data/system.ucf, but this haven't change anything. I've run out of ideas, and switched from TEMAC to other Xilinx stuff for a while.
