Im having issues with ethernet altera de2-115.
I have a design file with NIOS2 and TSE RGMII set using linux as SO from altera linux-sopcfpga. Everything works fine except TX of the ethernet chip.
When a issue a command I even see the TX led blinking but no data transmited, RX seems to work fine, using tcpdump I see de packages comming in and resquests for out packages, but no data transmited effectively.
I believe its a problem related to ENET_GTX_CLK but still have no clue what is going on. I tryied many options in dts file but no sucess until now.
using ifconfig I see a great numbers in rx packages and a small number in tx pacackes and some dropped packages in rx line.
have someone I clue or anyone had the same problem??
I read this PDF that's why I got so far :)
Is there a way to debug these signals with lite version of quartus?
Other think I notice is that the ENET1_TX_CLK (or zero depending which
ETH you are using) seems not oscislating, because when a use it the output TX led dont blink. It is a pin out of marvell phy.
Tried to supply this clock using pll the tx start blink but no data.
I will try loopback debug, mean while if someone knows anything else Im all ears.
