RE: [microblaze-uclinux] TCP transmit performance

["Brettschneider Falk" <fbrettschneider@xxxxxxxxxxxxxxx>]

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.
