Hi, http://www.earth.li/~noodles/files/delta.boot is interesting. How was it obtained? By the EXP connector on the back being the SoC's UART0? Any wiring details I can put up on http://inputplus.co.uk/ralph/emailer/ for others to follow? Thanks, Ralph.

E2's Boot-loader UART0 Protocol Semi-Available.
by Ralph Corderoy 02 Feb '05

Hi, I've added a little information the the serial protocol the E2's PBL bootloader talks over UART0. http://inputplus.co.uk/ralph/emailer/ (Sorry for the `drip, drip' of emails rather than one all-encompassing one, but I don't want to hold releasing information if I suffer from lack of time.) A later version of PBL is used in the E3 according to Jonathan's dmesg output. Cheers, Ralph.

Widen Scope of e3-hacking List.

Hi, The `About e3-hacking' paragraph on the Mailman page isn't filled in. http://www.earth.li/cgi-bin/mailman/listinfo/e3-hacking I was wondering if it could be stated that the list is willing to discuss the techinical side of hardware re-use of any of the Amstrad Emailers, i.e. the E3's predecessors too, along with any legal issues that arise from it. That's based on what private email conversations I've had have been covering in the last months. Cheers, Ralph.

Details of November 2004 CD Available.

Hi, I'm slowly updating my Emailer pages. Sorry it's so slowly. One recent addition is some details of a GBP25 CD Amstrad sent out in November 2004. As it says on the page, it would be interesting to know if the other CDs out there are the same or different. http://inputplus.co.uk/ralph/emailer/e3.html Cheers, Ralph.

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.)
