Re: [microblaze-uclinux] TCP transmit performance

It works fine for me. Grumbles about the signals but still works. I'm using v0.2, no mmu. Are you sure windows firewall isn't blocking anything? Has anyone else run netperf on v0.3? 

Here is my output:

Hi Jim,
thanks for your excellent tutorial! :-)

I started netserver-a4.exe on Windows and it's listening on port 12865.
Then I tried the netperf client on microblaze but it seems to have problems and crashes or hangs Linux after about 3 seconds. I also wireshark'ed on Windows but haven't seen any incoming packets from the microblaze system at all. This is what I see on uClinux console... Note it grumbles about those signal catchers (?). Any idea? Does netperf work for you? I've got PetaLinux-v0.3-rc1, you know.
