Small ARM board running capable of running Linux

($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

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 :-)

Try this:

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

Oh ya...this is based on the LH79524 with a 77MHz ARM720T with ENET 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.

looks good too.
