Have you got JTAG working on an E3? Maybe what I should have said in place of "desoldering the Nor" should have been a more general "without major modifications to the hardware" ? ;-) >-----Original Message----- >From: Jasmine Strong [mailto:jasmine@electronpusher.org] >Sent: 17 June 2005 10:41 >To: Discussion of the Amstrad E3 emailer hardware/software >Subject: Re: [E3-hacking] Making life easy for you > >What about using JTAG?

I think you'll find that if you dialup on that freephone number the Thus firewalls keep you constrained within their building - sure you can access your Thus based POP3 mailbox or send to their SMTP and do HTTP to the internal servers but you can't get out to the outside world on port 80 for example so the "fun" of getting free access diminishes fairly rapidly.

Making life easy for you
by Gavin Andrews 16 Jun '05

The reason I am interested in E3 hardware recycling is that the hardware is good value. It makes no sense to be to buy something at a reasonable price! It's the subsidy that makes the E3 make sense! Just being realistic. Regards, Gavin

We've been toying with the idea of taking Montavista's latest distribution which is a 2.6 - but at the moment we're working on the "if it ain't broke, don't fix it principle"! (and 2.4 works for everything in our specific application) > That's £100, isn't it? Or was it originally sold for more than that? £100 is roughly what we were thinking. I couldn't guarantee that it would be exactly that might be a bit more (or possibly less even). The more I look at other Linux dev systems the more I think £100 (inc the 480x320 colour LCD) is really cheap. Others have pointed me in the direction of www.gumstix.com and http://www.kwikbyte.com/KB9202_description_new.htm#BuyNowKB9202 as examples of other "cheap" dev systems. But they have dramatically less resources on the board and obviously no sign of an LCD, let alone a colour one. I guess it's just a shame doesn't have an Ethernet MAC on board but we'd expect most people to do what we do and get a USB-Ethernet adapter (we use Netgear FA101/Belkin F5D5050 for example) and use this for NFS based development (which is exactly how we develop for it) > Do I think you'd sell these for £100?

To be clear this (probably) wouldn't be in the style of an E3. We'd probably ditch a lot of the "telephone" gubbins. It'd basically be a box (maybe pressed steel or something) with an E3 board at the heart (maybe with modem section depopulated) and the LCD/backlight module fitted into the "roof" - a trailing cable would go to the PS/2 QWERTY as found on the E3. So it'd just look like a generic little computer in a box - nothing like a telephone. I think we probably would put a JTAG header on it for those interested in such things (though maybe this isn't such a necessity now that Linux is ported) > Personally, it's unlikely I'd buy a developer model at the start - not > because I don't want one, just that it's hard to justify even > more toys > at present. :) Fair enough. If you know others doing Linux development then feel free to mention this and see what they think. I'm just interested in as much feedback as possible right now to decide whether to launch off in this direction. While there (hopefully!) wouldn't be much work to be done on our part, there would be some and we need to gauge whether such effort would be economically justified.

Yup, if we do this we'll try to put together some documentation and will probably set up a BBS of some sort so that users can help each other. We'll try to be there too in order to answer questions first time round and then the BBS and maybe a FAQ that comes out of it will be the basis of added documentation. Internally we use Twiki as a central documentation point and I guess some of that could also be made available. We also have a whole load of (mainly Linux based) support tools that make generating things like module headers a lot easier. Not that I guess anyone would be using a module structure for anything other than the PBL loading LDR and then LINUX and maybe a CRAM based LNXFSYS. We also have a very pretty (Windows based) equivalent of pblq ;-) (not sure if we can release that as it stands but could probably do a cut down version or maybe just tell you what you need to know to implement everything in pblq (which has the advantage of not being tied to Windows). As it happens I think pblq has now got most of the stuff sorted anyway.

pblq 'n' stuff
by David Given 04 Jun '05

04 Jun '05

My E2 is still in a box. Somewhere. I currently have other things on my mind, such as getting my hot water working... Do we have a CVS (or other) repository anywhere that I can upload pblq to, in the meantime? There's stuff that needs doing to it, like support for the execute-code command that Otaku found, and the E3 support that... uh... someone hacked in (sorry, I can't find the message), and I don't think I'm going to be doing anything with it any time soon. Plus, at some stage I presume people are going to want to start hacking ucLinux or big Linux... -- +- David Given --McQ-+ "Under communism, man exploits man.

[E2 hacking] E2 monitor v0.22
by Matt Evans 27 May '05

27 May '05

Hello, I've uploaded the state-so-far of my monitor to: http://www.axio.ms/projects/e2/e2-monitor-0.22.tgz (the README from the tar is also at http://www.axio.ms/projects/e2/e2-monitor-0.22-README ) What it can do: o Provides basic monitor with commands such as peek/poke/go o XMODEM upload/download RAM over serial (though this is currently v.picky about terminal s/w used) o Read NAND flash to RAM o Write/erase NAND flash from RAM data o CRC32 chunks of memory o Initialise LCD a bit/provide simple string/hex printing to it o Boot from PBL What it can't yet do: o Search the rest of NAND for executable client programs, and boot them o Access SMC cards (I have been unable to coax PBL into accessing them, but it looks like much of the support is there in PBL. (Not necessarily complete/functional of course)) It's pretty fast at downloading data and writing it to flash, or just executing code, so I find it's a better development environment than EXP'ing stuff down with pblq-alikes. I've usually started up the E2, interrupted the splash screen over JTAG and downloaded the ELF (over jtag); now that it boots from flash, it'll accept a new version of itself via XMODEM and run that happily. (Whew, my Windows box is now unnecessary!) I don't know if anyone's interested in trying it out or using it; I'd be grateful for any comments, suggestions or code contributions! It's not really there yet - well, XMODEM works for me but probably won't for anyone else =] That's next on my list. -Matt ps: Here are the supported commands, from its help text: Help (commands are case-sensitive): h/? - This help dump <m|fd> <addr> <len> - Hexdump RAM or flash crc <addr> <len> - CRC32 memory get <addr> <len> - XMODEM download from RAM put <addr> - XMODEM upload to RAM flashwr <flash offset> <len> <ram address> - Write RAM data into flash device flashrd <flash offset> <len> <ram address> - Copy flash data into RAM listdevs - List flash devices go <addr> - Jump to address r{b|w} <addr> - Read byte/word w{b|w} <addr> <data> - Write byte/word fill <addr> <len> <byte> - Fill memory lcd <string> - Write string to LCD console [ fd above is a flash device ID, 0 = internal, 1 = external etc., as listed in listdevs ] [ All numbers/addresses/offsets are hexadecimal - zero padding is unnecessary ] pps: Any better names..?

How's your > E3 hacking going? :) I haven't really done anything recently, at least since getting shell access without having to take it apart. I compiled up a 2.6 kernel that I'd hoped might half work but flashing is a real pain. At some point I plan to add kernel boot support to pbltool using the store/jump codes Jake was talking about, but I've had plenty of other things on. Ideally I'd like 2.6 support, but 2.4 would be a good start if it had jffs2 enabled - the device at present just has a read only cramfs partition. Something writable would be much nicer and would make running OpenEmbedded quite easy. J. -- Eat a prune. Start a movement. | .''`.
