PL2303 cable
by David Given 01 Aug '07

01 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Many aeons ago I bought a PL2303-based mobile phone cable (designed for the N5100) which I was going to turn into an E3 cable. Then I moved house, and then I lost it. But recently I found it again, put the appropriate plug on the end (after figuring out the pinout), and once I realised that the reason it was producing gibberish was because I was testing it on my E3, not the E2 (which took about two days), discovered it works fine.

More e-mailers than I know what to do with
by Nathan Friend 15 Jul '07

15 Jul '07

Hello, I've been watching the list with interest for the last year or so. I have three e3's and two e2's. I have some Linux and electronics experience, any suggestions on what I could do with them. They contain too much fun hardware to just put on eBay... One of my plans was to make a website with howto guides etc, including photos of projects. Great to see so much activity in this community. Nathan.

Native build environment
by Martin Whitaker 15 Jul '07

15 Jul '07

Hi Folks, In response to the people asking how I built libspectrum / fuse, and in response to a few people who've asked me (outside of this mailing list) how to get started building applications for the E3 I've put together a 'how-to'. This 'how-to' caters for both Windows-only and Linux users and is aimed at people without a huge amount of Linux experience who don't want to deal with the hassle of cross compiling. I'm not saying cross compiling isn't the best way of doing it, I'm just giving an alternative. The location of the guide is: http://www.whitakernet.com/e3/ There is also a link to a quick 'how-to' specific to building libspectrum and Fuse, which includes the nasty hacks I did to it to get it running on the E3 (sorry Phil - I never did get chance to tidy it up!). I'd appreciate feedback from anyone who uses this system, there are almost certainly still problems with it so do let me know when things either do or don't work. Regards, Martin. -- No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.5.446 / Virus Database: 268.18.6/708 - Release Date: 02/03/2007 16:19

Newbie E3 owner
by lists＠mice-software.com 11 Jul '07

11 Jul '07

Hi, I recently bought a couple of E3s from eBay (£25 each exc. shipping, sadly I've had no luck finding brand new ones for £10 or whatever). One of them was clearly new and has v4.9, however the other turned out to have been used (looks new and still has stickers, but some parts of the packaging are missing and it has some woman's name in it, with PBL v5.1. And some phone book entries, although I can't find them in Amstrad's GUI... Anyway, I obviously bought both to play with, so I had a few ideas: 1) to set one up with a wired ethernet USB adapter and a hard disk (via a USB hub?), my plan being to make one of them into a small file/subversion server that's less power hungry than a Dell PowerEdge or whatever. 2) to set one up in the kitchen as a mini internet terminal, allowing people to look up e-mails/recipes, edit the shopping list, etc. via a wifi dongle 3) use the modem in one as a PBX endpoint to the public telephone system (allowing me to set up Asterisk/etc. on another machine), whilst having it work as a VoIP unit 4) Videoconferencing between other systems :) Anyway, has anyone tried any of these? I've had a look round the wiki and the past e-mails here but it's not really clear what the present state of drivers/etc. are - I don't mind working on drivers either (although my experience with drivers is primarily on OSX and a small amount on Windows) Finally, is there anything I can do with the v5.1 unit, or should I just send it back to the person I bought it from? I was wondering if anybody had succeeded persuading it to talk (by the looks of here and the wiki, no), or if anyone had tried anything more hardcore - I had the notion of trying to do something like putting the CPU into a hi-impedence state and attempting to write the Flash in-situ from an external device, or capturing the contents of the Flash as the system starts using an FPGA and attempting to reverse engineer it. Or is there something simpler like a JTAG connector? Thanks, Colin

What's the preferred distro for OE and e3
by Andy Collins 03 Jul '07

03 Jul '07

Hi folks, I've been taking a look at using OE to build bits for my e3 (now running Linux happily). What distro to you use to host your OE work? I've tried Fedora but there was a suggestion in the OE camp that it wasn't a good choice but no better alternative was suggested. What do you suggest? Thanks. Andy.

Newbie networking problems
by Andy Collins 24 Apr '07

24 Apr '07

Hi Folks, I've just received my first E3 and I'm cramming up on the info trying to get going. I've followed the info in the wiki about getting started and I get boot it up over the serial port now without a problem. My next milestone is to get t nrtworking and this is where I'm coming adrift. I've got a USB-ethernet adapter that is based on the ADM8515 chipset. When I plug it in I see... usb 1-1: new full speed USB device using ohci and address 3 usb 1-1: configuration #1 chosen from 1 choice and that's all. I think that the driver for the Pegasus will work with this chipset (though I may be wrong). dmesg gives me the following with regard to networking... usbcore: registered new driver catc drivers/usb/net/catc.c: v2.8 CATC EL1210A NetMate USB Ethernet driver usbcore: registered new driver kaweth pegasus: v0.6.13 (2005/11/13), Pegasus/Pegasus II USB Ethernet driver usbcore: registered new driver pegasus drivers/usb/net/rtl8150.c: rtl8150 based usb-ethernet driver v0.6.2 (2004/08/27) usbcore: registered new driver rtl8150 So that's as far as I've got. I can't see /dev/eth0, which I would expect. ifconfig just shows my loopback device (should it show more?) Please folks, what do I need to do next to get in on the network? Thanks. Andy.

Keymap
by Stephen Bowyer 25 Mar '07

25 Mar '07

Hi. Once I managed to boot Linux on my E3 I was quite frustrated with the default keymap. I found a keymap in linux-2.4.18-mv30-E3.tar.bz2, but it took me a while to figure out how to convert it to a busybox compatible binary kmap file. I've put the busybox compatible and original keymaps online, incase they're of any use to anybody. http://widearea.org/ste/amse3/delta.kmap http://widearea.org/ste/amse3/ams_delta_keymap.map Cheers.

Building MPlayer
by Mark Underwood 04 Mar '07

04 Mar '07

I've managed to build a very cut down MPlayer for the E3 which now allows my to listen to internet radio stations (only mp3 ones at the moment as that was all I wanted to start with). I downloaded the latest version of MPlayer untared it and run the following configure line. ./configure --target=arm-linux --cc=arm-linux-gcc --as=arm-linux-as --host-cc=gcc --prefix=$ROOTFS --disable-mencoder --disable-langinfo --disable-lirc --disable-lircc --disable-vm --disable-xf86keysym --disable-radio-v4l2 --disable-tv --disable-tv-v4l1 --disable-tv-v4l2 --disable-tv-bsdbt848 --disable-pvr --disable-rtc --disable-winsock2 --disable-dvdnav --disable-dvdread --disable-mpdvdkit --disable-cdparanoia --disable-bitmap-font --disable-freetype --disable-fontconfig --disable-unrarlib --disable-sortsub --disable-fribidi --disable-enca --disable-macosx --disable-maemo --disable-vstream --disable-gif --disable-png --disable-jpeg --disable-libcdio --disable-liblzo --disable-win32 --disable-qtx --disable-xanim --disable-real --disable-xvid --disable-x264 --disable-nut --disable-libavcodec --disable-libavformat --disable-libpostproc --disable-libavutil_so --disable-libavcodec_so --disable-libavformat_so --disable-libpostproc_so --disable-libavcodec_mpegaudio_hp --disable-libfame --disable-tremor-internal --disable-tremor-low --disable-tremor-external --disable-speex --disable-theora --disable-faad-external --disable-faad-internal --disable-faad-fixed --disable-ladspa --disable-libdv --disable-toolame --disable-twolame --disable-mp3lib --disable-liba52 --disable-libdts --disable-musepack --disable-amr_nb --disable-amr_nb-fixed --disable-amr_wb --disable-vidix-internal --disable-vidix-external --enable-armv5te --enable-mad --with-extraincdir=$ROOTFS/includ --with-extralibdir=$ROOTFS/lib (you will need to set ROOTFS to point to where your rootfs is) When I tried to build MPlayer I found that for some reason it didn't bother to build and link in libavutil which it needs so I added the following lines to the Make file around line 269 (just after the ifeq ($(GUI),yes) bit) #MU hack, link libavutil COMMON_DEPS += libavutil/libavutil.a COMMON_LIBS += libavutil/libavutil.a Once you've done that just do make and make install. My plan is to intergate a internet radio program with Martin's phone dialer stuff so you can use your E3 to listen to internet radio (and yes it does work real time! I've tested it with a USB sound card). Cheers, Mark ___________________________________________________________ The all-new Yahoo!

Windows version of pbltool
by Martin Whitaker 03 Mar '07

03 Mar '07

While I was creating a setup to allow people who only has access to a Windows machine to work with the E3 I compiled a Windows version of pbltool. It's based around the pbltool-0.2 source from http://the.earth.li/pub/e3/, but has an extra command 'send' which allows the u-boot commands such as 'setenv' and 'bootm' to be sent from the startup script without the need to launch hyperterminal. A binary version of pbltool for windows can be found at: http://www.whitakernet.com/e3/files/E3_windows_tools.zip and the source (including Visual Studio project file) can be found at: http://www.whitakernet.com/e3/files/pbltool_windows.zip Noodles: Feel free put a copy on your website if you feel it's appropriate. If you find any bugs let me know (after you've fixed them, of course). There probably is because I can't say I've tested it a right lot - as soon as it worked I moved on </slap on wrist> -- No virus found in this outgoing message. Checked by AVG Free Edition.
