Hi Kazu,

I have enabled these settings except "Packet socket:mmapped IO" which it is no where to be find. Please take a look at attached screen capture (uClinuxNetwork_1.jpg and uClinuxNetwork_2.jpg) for the setting.

In QSYS, I change the clock to TSE IP from 50 MHz to 125 MHz (not a PLL output) to experiment if it makes a different, but the result is the same.

uClinuxNetwork_3 is a screen capture of the tcpdump when I ping from my PC (192.168.0.3) to the board (192.168.0.4). As you can see, the GX board does detected the incoming traffic and reply back. I believe the kernel isn't configure correctly somehow so it responds back with something the PC couldn't understand. There could be a bug in the device driver which I also did a quick check on the "altera_tse.c". The irq handler function does trigger when it is ping from the board to PC or vice versa. Do you know if the uClinux v3.7 have a new patch for the Ethernet?

Thanks for your help again,

Yeung
