I don't have another DIMM handy, so I couldn't test that.
Ok, just out of curiousity, I found another DIMM to try and test, but with 2 it hangs at the "DRAM: " message.
Is your dimm PC3200 DDR? Speeds match the current dimm? (It does have a spd eeprom right?)
An interesting thing to note here is, the 'ethaddr' value was automatically set somehow (is there auto detection support here?)
Hard coded in the config. Uses MY mac addresses.
So anyway I just entered the ones on the stickers.
u-boot has the mac addresses for my board in the config file... README.ocotea says (I think) change it for your own board.
group supported is group 4, so ensure you have the jumpers set that way. (J79, J80, J29, J31, J76, J81) are all 1-8 and 3-6.
Yes, I checked and they are correct. Still no joy. Other ideas? The network comes up just fine under PIBS with the same settings. Also, is loopback supported? I cannot ping loopback or the board's own ip address either. In addition, every time I try to ping, it always waits for auto negotiation. That doesn't seem normal.
Normal (autonegotiation that is). U-boot only init's the net devices when it needs them.
You won't be able to ping loopback or yourself, as u-boot is single threaded, only initiates net traffic, and listens for replies.
Another thing I noticed that doesn't seem normal is that the board seems to hang on the 'reset' command or after using the reset button on the board.
Ensure your switch settings are the following: U80: 2,3, & 6 on, all others off.
Incidentally, just for fun, I tried burning the image into the 4MB alternate flash and booting from that. It works just fine, other than flash detection getting a bit confused. :-)
The fpga handling code could use some sprucing up...
If there are any more questions we should probably take this offline.
