I am building a AT91RM9200 project for embedded control (no need to real time). My system memory is 8M Flash + 1-2M SRAM. I am thinking about using uclinux but in fact I can port my old ARM7 driver on to it.
Could you give me some pros and cons of using uclinux?
We looked at using ucLinux for an ARM project and found:
1) It chewed up 2+ megabytes of flash and >600K of RAM 2) The build/work environment for it was really hodge-podge 3) It's GPL, which means if you make any mods it infects everything you do
We found that a microkernel worked a lot better for us (www.freertos.org) without all of the headaches associated with Linux and far less memory use (about 25K). But in your case it'll depend upon what your project really needs. If you don't need UNIX compliancy, there are better alternatives.
