[U-Boot-Users] Re: IBM 440GX eval name
I also have a 440GX eval board from IBM. I tried the ocotea config and it boots up just fine. However, I get a message about an I2C read error. Is this normal? In addition, I can't seem to bring up the network. However, this is my first shot with u-boot so probably I am doing something stupid. The docs I have found so far are pretty good, but relatively unclear on the network setup. Is there something I have to do besides setting some environment variables? Or is there some doc that I missed? Thanks.

Great! Good to see some mileage from my port!
However, I get a message about an I2C read error. Is this normal?
Yes, and no :) Normal if you have only one (1) DIMM populated. If there are two (2) DIMMs you _*shouldn't*_ see that message. I don't have another DIMM handy, so I couldn't test that. If the message bothers you that much, you can remove the second SPD_EEPROM address from the config (do this locally though).
In addition, I can't seem to bring up the network.
See below...

Looks like you have one DIMM installed.

There's your problem. Do the following: setenv ethaddr XX:XX:XX:XX:XX:XX setenv eth1addr YY:YY:YY:YY:YY:YY setenv eth2addr ZZ:ZZ:ZZ:ZZ:ZZ:ZZ setenv eth3addr AA:AA:AA:AA:AA:AA
where the 'xx', 'yy', etc are the ethernet mac addresses for your board. (Flip it over, they are on stickers on the bottom of the board).
ipaddr=<ipaddr>
You'll want to set the others as appropriate also...
netmask=<netmask> serverip=<servip> gatewayip=<gwip> hostname=<hostname> netdev=eth0 stdin=serial stdout=serial stderr=serial
Environment size: 278/4092 bytes
=> ping <address> Waiting for PHY auto negotiation to complete.. done ENET Speed is 100 Mbps - FULL duplex connection ping failed; host <address> is not alive
Hmmm... since your setup is using EMAC0, ensure you have the cable in port 0. Also, the only enet 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.Good luck,

Ok, just out of curiousity, I found another DIMM to try and test, but with 2 it hangs at the "DRAM: " message.

Well, the '<macaddr>' in the above output was edited by me for the email purposes. Sorry about that. I have the actual mac addr in there but was masking it out since this list is archived on the internet. Similarly for the other masked settings.
An interesting thing to note here is, the 'ethaddr' value was automatically set somehow (is there auto detection support here?), but it was incorrect in the final byte, at least compared to any of the 4 stickers. I rebooted under PIBS and unfortunately got 4 more different mac addresses that also do not match the stickers in the last 2 bytes. So, they all seem to be valid IBM mac values for this board, but I'm not really certain which mac addresses are really mine for this board. So anyway I just entered the ones on the stickers.

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.
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.
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. :-)

Is your dimm PC3200 DDR? Speeds match the current dimm? (It does have a spd eeprom right?)

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.

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.

The fpga handling code could use some sprucing up...
If there are any more questions we should probably take this offline.
