I've got kernel panic while booting the gateworks kernel on my avila board, and since the step I took was a bit different from the manuals, I details my situation as per below;
The Avila board that I have is a custom order version, with 8MB flash, CF card slot, and for some reason, I cant use tftp to install the kernel and fs to the flash. What I did however was this (partly based on http://www.dd-wrt.com/forum/viewtopic.php?t=9763);
I've got no problem/error while going through the above procedure, except a confirmation dialog that appeared when i "fis create -n linux" which i guess is normal. The problem starts when
Code:
fis load linux
exec

Thanks, that solved the problem. I somehow hit another wall when the system failed to boot, stopping at setting up IPv4 over IPv6 tunneling driver as shown below. I dont know how this might relate, but could it be caused by the fact that our built in ethernet interface doesnt come with MAC address?

i just can tell you my experiences with the gateworks boards which are all comming with mac adresses and they are working fine. but a new release is already schedules. i just have still some things to fix within the webgui _________________ "So you tried to use the computer and it started smoking?

Ok, I'll wait for the new release, and I hope you can look into this if you have the time I'm pretty new new to this and to look at the thing myself, I need to be able to extract the firmware, which I still fail (refer to my other post; http://www.dd-wrt.com/forum/viewtopic.php?t=10140).
As I mentioned before, mine is a custom order board, and for unknown reason, ours doesnt come with MAC addresses.. Need to ifconfig ethX hw ether xxxx everytime the system boots (on our firmware based on gatework's SDK / uclinux, not ddwrt for sure), and for the same reason, I cant use tftp to flash the rom.

the firmware modification kit will only work for broadcom versions and is not compatible with gateworks images.
about your tftp problem. if you tell me how much memory is installed in your system, i can send you a new redboot image. but if your board has no mac's installed this could be the reason for your tftp problem too. then you just can flash with jtag. i can provide you a full jtag image if needed. but in any case i need the size of your ram memory.
but this will not help you out with your mac problem. this must be a fault of your board. maybe gateworks missed to preflash the mac data. so you must contact gateworks for fixing it. dd-wrt reads out the mac addresses out of a special eeprom section.
but i dont know if you can write to it. if yes. you can get access at /sys/bus/i2c to it. its stored as binary data in

Hi,
I'm having a trouble getting the access code as my board doesn't have an internal rom mac address. Thus, I cannot connect to the board for activation via eth0 interface. This is a special board from Gateworks. Actually there is a trick to bring up eth0 interface on this board by using command:

no this trick will not work. ixp0 and ixp1 are the ethernet interfaces. eth0 does not exist. if there is no eeprom with mac addresses on the board, the whole thing will simply not work. the activation requires this eeprom _________________ "So you tried to use the computer and it started smoking?
