RE: [E3-hacking] Developments

Jonathan, I haven't forgotten about this but right now I'm knee deep in DRX180 and DRX280 Sky+ boxes and haven't got the time to go ferreting for the bits you need - but I will when I get a moment. Oh, and for the benefit of others, the way the phone works is that at a minimum of 24 hours it will call the server on an 0901 number to send/receive email. If you instigate this manually then you just reset the 24 hour counter. So it never goes more than 24 hours without making a 15p (is it?) call. This is unavoidable and is a condition of use quoted in the Ts&Cs when you started to use it (see also the red letter warnings all over the box and the plastic baggy that the manual comes it) - we don't make a secret of this - it's how you buy £100 worth of electronics for £29. We would eventually like to see that other £70 back and perhaps a few sheckles of profit too ;-) Independent of the email call there's also a system by which the phone can be triggered to dial out and pick up some adverts during the middle of the night. The call out from your phone is made on an 0808 number which is in the same charging band as 0800 (but for data). This means that such calls cost you, the end user, absolutely nothing. There are various other charges involved with optional functions on the phone such as sending SMS messages or surfing but the bottom line with those is if you don't want to pay don't use the function. The only obligatory call is that 15p/day for email. (apologies if I got my facts wrong and it's more than 15p these days - it's been a while since I was involved in the day to day running of the service) Cliff > -----Original Message----- > From: Jonathan McDowell [mailto:noodles@earth.li] > > I believe sound is still > the major > piece of the puzzle that's missing; This e-mail and any attachments are confidential and intended exclusively for the addressee.

Just thought I would let everyone know that sound now works (capture and playback). I'll clean up my work and post it tomorrow. Mark ___________________________________________________________ Switch an email account to Yahoo! Mail, you could win FIFA World Cup tickets. http://uk.mail.yahoo.com

That's exactly how we did all the E3 development - with Netgear FA101 adapters which are a Pegasus compatible chip and then mounting the root over NFS. We also found that Belkin F5D5050 worked well. I'm kind of surprised that y'all weren't developing over NFS already and debugging using gdbserver at one end and gdb/ddd at the PC end.

Networking
by David J. Singer 24 May '06

24 May '06

I've just been playing with a "Pegasus II" type USB -> ethernet dongle on the E3. It's quite neat having an internet connection on it! I've been browsing the web using the "links" browser :) Is this the way others are networking their E3s? Or are people just accessing them via the serial line. It's would certainly be handy to NFS mount the root directory...! -- David J. Singer doc(a)deadvirgins.org.uk "Time flies like an arrow, fruit flies like a banana"

This sort of thing is better asked on the e3-hacking list rather than direct to me. gcc is the obvious cross compiler to use. I believe there are numerous guides around for building it in a cross compiling configuration, but there are at least 2 options that make it easier: * buildroot (http://buildroot.uclibc.org/) This is what Mark's image (the one you can download) is built using. Fairly quick to get going; you can use the BR_config in E3_release_v1.tar.gz * OpenEmbedded (http://www.openembedded.org/) This is a lot more involved to get going, but does offer a huge number of packages. It's the basis for Familiar (the iPaq distro) and OpenZaurus and David Ford's patch to support the E3 (including building u-boot and the kernel) was recently added to it. J. -- Revd.

notldr release.
by Jonathan McDowell 18 May '06

18 May '06

I've put my initial release of !LDR up at: http://the.earth.li/pub/e3/notldr-0.0.1.tar.gz It'll compile up to a ldr.img file that you can put in /dev/mtd3 and loads 128K from /dev/mtd1 to 11f00000 and calls it ie will just load u-boot and no more. In addition the u-boot diff I'm currently using myself is at: http://the.earth.li/pub/e3/delta-20060518.diff It'll automatically boot a kernel from /dev/mtd0 if no key is pressed with 30s of loading, which is plenty of time to interrupt it but still allows an unattended boot. No prebuilts of either of these yet. I have a cunning plan to do some sort of installer that you'll load the basics of over pbltool which will then pull in everything else off a USB memory stick, as well as backing up a virgin E3. Dunno how achievable it is nor when I'll find the time. J. -- Revd. Jonathan McDowell, ULC | noodles is as per the who standards

Trying to load u-boot from NAND.
by Jonathan McDowell 18 May '06

18 May '06

As I've discussed on IRC I've been trying to write a simple 2nd stage bootloader that PBL will load from NAND that will then load u-boot. An uncompressed PBL block seems to have a limit of 16k, which is far too small for u-boot and I don't want to get into replacing PBL with u-boot entirely without JTAG. Anyway. While I can init serial and flash the LEDs, I don't seem to be able to manage to even ident the NAND. My code isn't a lot different from the NAND code I wrote for u-boot and the kernel, so I'm not quite sure what I'm doing wrong. I've tried a dumb loop as a delay, as well as the cleverer timer based delay routines that u-boot uses. But I don't think this should be the problem, as as long as the delay is the minimal length it shouldn't matter if it's more? The code is at: http://the.earth.li/~noodles/ldr-new.tar.gz It's rough and ready, but please, someone tell me what blindingly obvious thing I'm missing that means it doesn't work!

RE: [E3-hacking] E3 Memory Map?

David, As others have said, the contents/layout of the Nand probably isn't of much use to you as almost any "non Amstrad" use of the phone is either going to wipe the chip and use the entire Nand as a filesystem or just leave it alone and ignore it completely. But if it concerns you I can post some detail about what goes where "as delivered" as I know you guys can work this out "by inspection" with pbltool (etc.) anyway. However do us all a favour and fix the clock on your PC. Unless you are in a different dimension I cannot believe that it is 19:08 BST where you are because it's still only 18:09 BST as I send this.

E3 Memory Map?

Jonathan McDowell wrote: > It's all been discussed on the list before. The archives are publicly > available; it's well worth going back and reading through them. Well, as I said in my original posting, I *did* spend some time looking though both the archives and the wiki. I guess, being comparatively new to all this, it just isn't as obvious to me as it is to you "old hands". Hence my suggestion that it would be good to have it clearly shown in the wiki for when the next akward b*gger like me comes along! :) In any case, thankyou for your replies. I have a much better idea of what's going on now. Incidently, I wasn't joking when I said I had the datasheet for the camera. I can't remember offhand who said they were working on it (Matt, perhaps!?) In any case, email me if you'd like me to forward it. -- David J.

E3 Memory Map?
by David J. Singer 17 May '06

Matt Callow wrote: > using pbltool with the default linux.pbl as provided by Mark wont touch > the Amstrad code - it only writes to RAM, so a powercycle of the E3 will > bring it back to it's default state. Okaaaaay.... I really beginning to get the feeling that I'm asking for privilidged or restricted information here, and no one wants to say "we're not going to tell you that" :-) Last try. Please could someone detail the memory map. Address ranges of NOR, NAND; SDRAM; location of Amstrad code, PBL loader, that sort of thing. At least then I'll be able to make more informed choices about where I can put my own code and stuff... As an incentive, I have an Omnivision OV6650 datasheet for the first correct respondant! :-) -- David J. Singer doc(a)deadvirgins.org.uk "Time flies like an arrow, fruit flies like a banana"
