Small ARM board running capable of running Linux
Don Gravos
RS232+general purpose parallel I/O lines+multiple channel ADC+realtime clock
and capable of running Linux. (Am I sking too much?)
Do you know ARM board with these specs?

The new AT91SAM7X comes close, but no Linux. Other OS's however. See
www.freertos.org/portsam7xiar.html

Sorry, wrong link. This link shows the Ethernet and the USB on the SAM7X:

A Gumstix, plus an EtherStix and a Robostix or Audiostix expansion
boards would give you everything but the realtime clock. The serial
ports are TTL level though, not RS232. The Robostix board has on
on-board AVR which provides multiple GPIO and ADC, the Audiostix
provides fewer A/D and GPIO but saves you having to write for two
platforms (and you get audio - hence the name).
It is small (very small) and runs Linux out of the box.

Why running Linux? Takes up a lot of room and adds a layer of
complexity.
Just program the board most embedded systems don't have an RTOS anyway.

I like the Gumstix, but they only have USB client.
I just ordered a Linkxys NSLU2. While this would still need
something else for ADC and GPIO, it has Ethernet and 2 USB
ports. It also has 1.5 serial ports (one of them is read
only.
And yes, Linux runs on it.

You mean uclinux or linux ?
How much do you want to spend ?
Usb host or just usb for programming / or usb to serial ?
www.gumstix.com as others have said.
Otherwise uclinux especially with arm7
Maybe one of the many lpc2xxx based boards
www.olimex.com/dev makes a few but not with all the features you want
buy from sparkfun.com as can order online without faxing credit card details

http://embeddedarm.com correct link
Any idea what the IO levels are ?
Found it in the manual
http://embeddedarm.com/Manuals/TS-7200_Rev1.3.htm#DIOHeader
3.3V source 4mA sink 8mA
not 5v tolerant.

Oops, just noticed the USB requirement. Yes, the Gumstix folks are
taking their time over sorting USB host. It's in the pipeline
allegedly, but I'm not holding my breath.
Captain Dondo
Different parts of the board have different IO levels; 8 pins are 3.3V;
others are 5V. You will need opto-isolators or similar in the real
world (but don't you always?) You can also get daughter boards with 5V DIO.
I have one in hand and am building the power supply as we speak. Nice
unit, tiny, but I have a bunch of work to do before I start playing with
it - need to build a DIN rail mount for it, etc.

www.mechatronicbrick.dk could do the job with the right motherboard.
Both have Ethernet, USB Host + Client, 2 UARTs (chips got 4)
SPI, I2C , GPIO, RTC. No ADC on the mech'brick AFAIK.

There is a growing movement to use one of the wireless routers (like a
linksys wrt5x?) which is an arm based Linux with a wireless capability
built in. There are also hardware hacks to add serial ports on the web
... and other mods available. This for about $40USD, with power wart,
enclosure, antenna and all that ... google is your friend ...
Cheers,
Rob.

Yes, but that $50 is a bogus price, it's a few thousand dollars to get
set up and the $50 is only for a mini module that requires a baseboard
to get any actual functionality.

The ETRAX 100LX Multi Chip Module includes the ETRAX 100LX SoC plus 4 MB

Ethernet-connected Linux systems.

I had a look at axis a little while back but I couldn't find any info on
the MIPS rating. Also I found that the 10/100 Ethernet is slugged to a max
2 (or 2.5) MB/s. Somthing to do with the USB interface.

A little correction : they are effectively starting arount $50 in volume
orders (1K), see their prices on their web site. These kind of modules are
COM, meaninf effectively that they are designed to be fitted, like a
component, on your application PCB. So yes a baseboard is needed, but it
could be either a standard one (PC104 or ATX, around $30-$40), or your own
application PCB.

($50+$40) x 1000 = $90,000. That should be enough to build any custom
board you want. We can even throw in 10,000 spare PCBs.

Which etrax chip ?
There is a whole range since 1993
http://developer.axis.com/products/etrax100lx/etrax_history.html
The 100LXsupports 100Mbs full duplex
They are used by Axis in their surveillance cameras
one of their boxes has an etrax 100LX + TI DM642 + camera chip.
Also if the ethernet wasn't up to scratch , why would the chip get used in
routers , network cameras , nas boxes etc ?

Elphel do seem to use broadcom ethernet on their cameras
Sergio Masci
I didn't make a note at the time and now that I've gone back to check, the
docs look different so I cannot say with any certainty. It was
the one used on the Axis product.
Previously I saw no mention of seperate ethernet connections now I see
that there is mention of a primary and secondary connection one going
through an internal USB port and limited to 12MBit/s. Quote "Actual
routing speed is ~XX MBit between the two interfaces"

You tell me. Why do some NIC's perform MUCH better than others even though
they are all spec'd at 100MB?
Just because the hardware can pump out a packet at 100MBit doesn't meen it
can sustain 100MBit throughput continuously.

I must admit that when I first looked at the Axis docs I did not like what
I saw and I felt it was possibly overhyped overpriced hardware jumping on
the Linux bandwagon. I felt it was safer for me to alert people to a
potential problem and for these same people to then check for themselves
BEFORE buying the kit, than for them to buy the kit and find out AFTER the
event that there was a problem.
Anyway thanks to your posting I will give this Linux on a chip thing much
more scrutiny before dismissing it again :-)

There is a free 2.6.x linux port as well. goto
http://www.sharpmcu.com. You can sign up for their freely available
software library and it should be in there.

MAC, USB, ADC, RTC, GPIO, etc. There is a LCDC but if you don't need
it, it's nearly free and leaves you with extra GPIO. There is a 16-bit
data-bus version as well that may be easier to handle cause its a QFP
rather than BGA. The QFP version is the LH79525.
