Hi, I'm something of a Linux newbie so be generous. :) I'm running busybox on my E3 as per the wiki and I also have a Pegasus USB Ethernet adapter working with a static IP on my LAN.
Can anyone tell me: - What is the command to auto-configure the E3's IP address via dhcp? - Can I turn off the E3's LCD screen and just enter commands via telnet? - How can I compile and run Energymech (an IRC bot)? - How can I run dircproxy (a caching IRC proxy server)?
In the case of dircproxy, I already transferred an ARM binary to the E3 via wget, chmod 777 and tried to run it, but I just got a 'permission denied' error.
Would be grateful for any info. Thanks :)

You will need to run a dhcp client. Depending on the busybox configuration, it may be built in (It's been a while since I booted by E3). Try: udhcpc -i <INTERFACE> where <INTERFACE> is the name of your ethernet interface (probably usb0 or eth0)
If that doesn't work, try: busybox udhcpc -i <INTERFACE>
- Can I turn off the E3's LCD screen and just enter commands via telnet?
Not sure if you can turn off the LCD, but you can probably turn off the backlight. Not too sure how though. If you run a telnet daemon (again, this may be already compiled into busybox), or better still sshd (dropbear) on the E3, then you should be able to log in via telnet/ssh
- How can I compile and run Energymech (an IRC bot)?
You will need to set up a cross-compile environment. I used scratchbox, but others on this list have used openembedded
- How can I run dircproxy (a caching IRC proxy server)?
Again, you will need to set up a cross-compile environment
In the case of dircproxy, I already transferred an ARM binary to the E3 via wget, chmod 777 and tried to run it, but I just got a 'permission denied' error.
This could be because the binary is for the wrong ARM architecture or, more likely, it was built using libc rather than uClibc.
Would be grateful for any info. Thanks :)
Hope that's of some help.

Sorry for hijacking this thread. I just wonder if there is any chance to convert the E3 into a video conference station? If so, what software do I need to install on E3? Many thanks, David

Sadly the E3's a bit underpowered for that kind of thing. You could try Ekiga but it'll be really slow.

Does make one wonder the original purpose of selling the E3 as a video phone. Surely if it was good enough to send video over phone lines it must have enough juice to do (albeit slow) video over internet? Would be interesting to see what could be achieved.
Speaking of getting sidetracked, has anyone thought of porting any of the Open Embedded stuff over to the E3. Could spur on some much needed development in this area methinks.
Just a thought....

Perhaps the former was possible with hardware assistance by one of the ICs that's not used under Linux? I've a hazy memory of what the E3 has.

Or perhaps http://www.angstrom-distribution.org/ instead of OE. BTW, does anyone have an opinion on the TI OMAP-based BeagleBoard for USD149?
http://elinux.org/BeagleBoard http://beagleboard.org/
You get just the board at that price, but it still looks quite neat.
Cheers,
Ralph.

Yeah that is kinda what I meant. I have been playing around Angstrom on my Pocket PC and thought the whole bitbake monotone thing was quite easy. It occured to me that if the architecture is basically supported all that is needed is to port a few drivers across and put it out there for other developers to fill in the blanks.
Of course I am probably massively over simplifying things but it is probably not my imagination that I seem to be seeing more and more embedded devices running Linux of all sorts of flavours.
Just a thought...

Hello! Hope you are well, it's been a while since we last emailed and I hope everything's tootling along nicely for you. I saw your message on the E3 list,

... and I thought I'd mention that I've just picked one up this week -- I had originally ordered it from Digi-Key to the USA (with the view to picking it up there at some point) but they noticed I had a UK billing address, phoned up and declared they'd changed their minds and they DO ship to the UK now. (It was originally marked as export restricted!) So, they sent it via UPS courier to me for a total of £82+VAT (which works out about £10 more than the dollar price including $5 shipping to 'somewhere in the US'). Not too bad, I thought.
Anyway - the board is very cute and clearly hugely powerful. I note that TI have actually released some free compilers for their C64+ DSP core in it, too, but even ignoring that the ARM Cortex-A8 is a super chip. I have literally just received the board and consequently have only had an evening to play with it (almost got it booting from my dodgy CF card, the demo rootfs then trashes my ext2 partition -- but I figure as long as there's a working kernel I'm alright).
Of course it was an impulse buy and I don't actually have a use for it yet, but I figure something will occur... :D (MythTV/DVB MPEG2 player for upstairs over WiFi, or playstation emulator or something?) :)
All the best,
Matt

I was planning to use one as a desktop PC. Given that all I ever seem to do on my desktop machine is play video, read email and surf web, there's very little I couldn't do on a Cortex-A8 at less than one watt, that I can do on this Mac at a couple of hundred...

A while back my desktop PC blew up and I had to use my Asus eee as a desktop replacement. Plugged into my 19" monitor and full-sized keyboard it was surprisingly usable --- and completely, *totally* silent. I am now hooked on computers with no moving parts.
Does the A8 have an FPU? The literature I've found is a bit evasive, using phrases like 'floating point capable' but linking to the DSP. Is it powerful enough to decode video without using the DSP? Is there any useful open source software that can use the DSP for doing that sort of thing?
Also, it's a bit of a shame the Beagleboard doesn't have any onboard ethernet and a bit more memory (128MB is definitely pushing it) or it'd be an fantastic replacement for my home server (currently an elderly Shuttle that runs rather warm and loud)...

The A8 implementation in OMAP3430 has the VFP (actually, it has the Cortex VFP, which is better than the ARM11 VFP). So yes. It also has Neon, I think- which is sort of SSE3-like.

Yes.

Not sure. Probably not (yet ;-) )

Well, you *do* have USB2... but gigabit ethernet would have been nice.

I agree- especially as the OMAP3 EMIFF (or whatever they call it now) supports 1 Gbyte DDR DRAMs...

Handy with a scalpel and microscope? You could always upgrade the package-on-package device =D (CPU is on the bottom...)

Along time ago I looked to see if linux could use the DSP in the OMAP processors, I did find a framework that allows acces to the DSP under linux which is integrated into the OMAP linux tree, however I am not a coder and totally lost when it comes to DSP's so I have no idea how good/bad it is. It looks like you would also have to roll your own DSP tasks unless somebody else has written a DSP task that does what you want. You can find more information about it here: http://dspgateway.sourceforge.net/pub/index.php
Does not support the 3430, so won't work on Beagle, but does support the elderly OMAP in E3.

It is a fabulous idea though -- I don't remember the name of the product but a year or so ago there was a portable PPC linux-based pocket-sized computer, the idea being you would carry around your personal desktop workstation in your pocket (instead of just a USB stick) and plug in anywhere you liked, with your own familiar desktop. The size of the BB (post-it size) and the fact it'll easily power from USB & be a USB networky gadget out of the box is ideal.
Maybe I should make machined travel cases for it! ;)

No, not too bad. I found http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=296-23428-N... which seems to match at GBP81.95.

Was playing with one of these yesterday. The Cortex-A8 is a serious speed demon. At least fifteen times faster than the OMAP in the E3.

The DSP half of the OMAP is used for the codec stuff I believe. Assuming you can write the appropriate DSP code I can't see why it shouldn't be capable of acting as an IP video phone.
Of course we still haven't got full duplex sound working with the handset, which is a major stumbling block. I'd meant to play with the evilness of talking to it over the modem chip some more; I'd had success with half duplex and wondered if upping the baud rate might allow full duplex.
Speaking of getting sidetracked, has anyone thought of porting any of the Open Embedded stuff over to the E3. Could spur on some much needed development in this area methinks.
On my todo list (which never gets any smaller) I have looking at updating to recent u-boot; checking latest kernels compile and updating to the latest OpenEmbedded (probably using EABI). Or maybe Emdebian, but I think it's a bit big to install to the internal flash still.
