Hi Glen. I don't know if it's written anywhere, but you just change the base address of the controller. you can use the tinyshell to find the base address. The offsets are the same for both ports Here's something I chopped out of one of your parspec scripts: regwrite reg_ip 0xc0a8030a regwrite reg_10GbE_destport0 4001 ---> setb x40000000 <-------- Change this. writeb l 0 x00000060 writeb l 4 xdd47e301 writeb l 8 x00000000 writeb l 12 xc0a8030b writeb b x16 x0f writeb b x17 xa1 When Dong was here, I think we had his design working on both ports if you can find his scripts.
