Small ARM board running capable of running Linux

clock

The new AT91SAM7X comes close, but no Linux. Other OS's however. See

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.

embededarm.com - pretty much everything you need. You will need a daughterboard or two.

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.

How about the VCMA9?

I've used them, although with Nucleus rather than Linux, and they seem quite good.

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.

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.

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 ...

CM-X255 or CM-X270W from Compulab, starting around $50 ? Cf

Do they run Linux?

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.

For full linux

Etrax from Axis

The ETRAX 100LX Multi Chip Module includes the ETRAX 100LX SoC plus 4 MB Flash, 16 MB SDRAM, Ethernet Transceiver, etc. This chip is ideal for 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

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.

Friendly, Robert

Not strictly ARM, but take a look at

($50+$40) x 1000 =3D $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

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 ?

Alex Elphel do seem to use broadcom ethernet on their cameras
