See the first line of http://www.earth.li/%7Enoodles/files/delta.boot (linked from http://www.earth.li/~noodles/hardware-e3.html).

Hi, Bought an E3 back in 2008 Not done much with it till now. Wanted to start developing on it again but the files on the ftp server are only up to 2.6.19 and muru only has upto 2.6.27. Can anyone provide me with the latest kernel patch / buildroot config files?

Just got an e3 - where do I start

Hello e3 hackers, I just received an e3, which to start with I'd just like to get a kernel to boot on (not quite sure what I'll do with it yet - but that will come later). The guy that gave it to me me said it had been in storage for some time, so fingers crossed that it has not been updated. I don't know yet because I haven't got a compatible PSU yet! If I understand correctly it's the proprietary bootloader on the 128Kb NOR flash that may have been updated making it difficult to hack? Would it be possible to get around this by flashing manually (using an AVR or similar?) If so would anyone be able to supply the correct binary image for the flash? Assuming I can pass this hurdle, what is the shape of linux support for this now? I see from reading the mailing list that the late 2.6 series worked fine... how about 3.x? How about defconfigs with full (or as much as possible) hardware support? I am happy cross compiling a kernel... I guess I can use any old ARM cross compiler? What exactly is the boot process and how does this limit the size of the kernel image? There's a way to get uboot on there - how can I do this? Does the kernel always need to be sent over serial? Sorry for all the questions, but without reading the entire mailing list there doesn't seem to be an easy way to find answers! Thanks, Ed
