Building a cheap Linux-capable circuit.

Why do you need Linux. If the BOM is a lot more important than development cost, Linux only is viable for quite complex devices. For many devices there are alternatives with a lot smaller footprint (e.g. take a look at

They have a single chip device, including processor, ethernet, memory etcetera. Add a power supply, connector with transformer for ethernet, rs232 chip and you've got a complete system running the 2.6 kernel. There are also a couple of dev boards available.

I don' think that's the sort of cheap I mean :-)

I can buy the Samsung 2410 CPU for $10ish, and a single NAND flash and RAM, and have a working chipset for around $24. I'm building a PCB anyway.

My question is, really, are there any ARM-9 CPUs I've not looked at which list much cheaper?

I don't need Linux... but our current product is built on it. If I go for something like an AT91SAM256 device, we are into a much longer development cycle. ( and probably an RTOS sign-up )

Cirrus CS9301/CS9302? Should quote well under $10 in reasonable volume. I'm shooting for a 32M/32M core with Ethernet for around $20.

funnily enough we have lots of experience with the EP9312, and had pretty much come to the conclusion that the 9301 was the best way to go cheaper, quickly.

I wish it booted from NAND though :-)
