I've now received this and it's linked from: http://www.earth.li/~noodles/hardware-e3.html Interesting (to me at least) points: * Camera source included and seems to present as a standard v4l device. * The keyboard driver is a module (not included) - there's a stub present presumably so basic init works. * The Pegasus USB networking module is compiled in; I've confirmed it initialises such a device, but see no network traffic (CONFIG_IP_PNP and friends are enabled in the .config provided, but I guess this may be from a debug tree?) * There's Belkin USB serial device support in the .config as well, but I can't see any output when I hook up such a device. I've setup a list at: http://www.earth.li/cgi-bin/mailman/listinfo/e3-hacking for anyone who wants to discuss the hardware/software of the device. What I'd really like to see is a dump of the flash from the device, in the hope that the startup scripts might do something with the ethernet. However I don't have the appropriate kit to be able to do this. Alternatively it looks like there's a serial console on ttyS0 (UART1 on the OMAP?), but I can't see any obvious pads where that's brought out to. (Oh, and as a semi related aside; if anyone has GPL contacts in Linksys I'd be most interested to know about them - I'm completely failing to get hold of kernel source for the WMA11B, which runs 2.4.17-rmk3-cot1.)

Which turns out not to actually be what they're using; what I have source for is "2.4.18_mvl30-E3" whereas my E3 has "2.4.18_mvl30-ams-delta". Also there's no sign of a dfdblk/MFS-DFD driver in the provided source, but the dmesg output of the E3 clearly shows such a driver initialising before any filesystem is mounted, ruling out the possiblity of it being a module. I contacted Amstrad about this over a week ago, but to date haven't had a response. J. -- 9 out of 10 men who tried Camels prefer women.
