[PATCH] Add support for Amstrad Delta (E3).
by Jonathan McDowell 08 Oct '06

08 Oct '06

The attached patch adds support for the Amstrad Delta (E3) Videophone. Currently the Amstrad primary bootloader provides the main hardware initialisation and then loads u-boot to handle user interaction and kernel loading. I'd appreciate any comments you may have. Patch is against current git. J. -- noodles is realistic with a few teen issues This .sig brought to you by the letter Y and the number 42 Product of the Republic of HuggieTag

Opie on the E3 woes...
by Brendan Berney 30 Aug '06

Hi, Thanks for those tips... Sean, you had it right... It now boots with the delay (although it then runs into other problems further down the line....which I'll have a look at). Cheers! Brendan PS.. And it was /dev/sda1 - typo there....

Opie on the E3 woes...
by Brendan Berney 30 Aug '06

30 Aug '06

Hi everyone, Firstly, let me just say that I'm V. impressed with the work everyone on this group is putting into this. When I first saw one of these things in Tesco for next to nothing I though - cool, now I can do a yell.co.uk lookup without having to wait for a laptop to boot etc. Anyway, with a view to this I plodded off to OpenEmbedded and started playing. At first I manually patched the OE snapshot using David Ford's patches and managed to build the uImage, bootstrap image and a (massively cut down) Opie image. My first problem at that stage was, and still is, how to get the E3 to 'see' the rootfs. Here is what I did: First I got hold of an old 128MB usb flash card and formatted it as an ext2 fs. Next I 'untared' the rootfs.tar.bz2 file that bitbake and OE had generated onto this with the result that I had a perfectly readable root fs on the USB stick. I then created an 'opie' pbl file thus: write 0x11900000 uImage-amsdelta-20060606090139.bin write 0x11f00000 u-boot-amsdelta-1.1.4-r0.bin exec 0x11f00000 which successfully loads the bootstrap and kernel images into the e3. At the u-boot command line, I issued the following: setenv bootargs mem=32M root=/dev/sda0 rootfstype=ext2 and then... on the bootm command everything appears to work...at first. Ultimately I get stuck with: VFS: No root yet, retrying to mount root on sda0 (unknown block(0,0)) Kernel panic: Unable to mount root fs on etc.etc. Please let me know what I am missing, no doubt I have done something stupid. I seem to remember that maybe I need to pivot the bootup using a ramdisk but don't know how to do this... My second problem is that, having noticed that recent OE snapshots no incorporate the work to date, I set off to try with one of those and rashly deleted my working snapshot... Anyway whilst I can get (with much fiddling) a UImage and bootstrap image built, I cannot get an Opie image anymore :-(. There seem to be many clashes between certain parts (such as bluetooth support) and the newer kernel. Does anyone have a recent OE snapshot that works and is prepared to put it up here? Cheers all, Wiretrip (Brendan Berney)

RE: [E3-hacking] AT commands to make voice calls - need help!
by Martin Whitaker 15 Aug '06

Hey again! Just an update incase this information is of use to anyone else. I've managed to make a normal voice telephone call using the E3 through the handset. Here are the commands I used: ATZ AT+FCLASS=8 AT+VIP ATM0 ATX0 AT+VNH=1 AT+VLS=2 ATDT<number>; You can probably get away without some of those - the important ones really are: AT+FCLASS=8 <places the modem into voice mode> ATM0 <turns off the internal speaker> ATX0 <prevents looking for a dialtone before dialing - you may not need this> AT+VLS=2 <selects the handset as the analogue source / destination> ATDT<number>; <note the semicolon at the end - this causes the modem to make a voice call not a data one> Noodles suggested the use of ATM0 - works a treat! Thanks.

The Tesco Extra in Kingston Park (Tyne & Wear) do have the E3 for £14.98, I just bought my second one from them today so I can now worry less about breaking at least one of them ;) Also the PBL is the all important 4.9 version too :D

Hi folks, According to this post, http://www.dvd.reviewer.co.uk/forums/thread.asp?Forum=223&Thread=585777&Typ… the E3 price is very low in some Tesco stores. I checked my local store (Cowley Road, Oxford), but there was no sign that they had ever stocked the E3, but you might be more lucky. Cheers, Ian.
