I'm no expert in this field, but here are my $0.02 worth

Learning curve isn't that great if you're familiar with Linux. eCos has a
Linux-compatible API so programming it shouldn't be too hard. eCos is a
*real* RTOS for time-critical operations (i.e. controlling a nuclear
powerplant or factory machinery or chemical plant). ucLinux is merely a
patch to enable Linux to run on 'simpler' processors (with no MMU).

Choosing therefore depends on the application. If it isn't a time-critical
software then use uCLinux. Both systems run on normal x86 PC's so it's easy
to test and use either of them.

Hi Ram,
    I'm no expert, just someone making the same decisions for the first time
and a little disappointed that nobody with more experience has replied.
Here's a couple of links I found interesting.

Hello,

I need for a new project a free small OS for the Intel xScale architecture
(strong ARM) IOP80331.
I consider both eCos and uClinux and the driver requirement is minimal.
Can somone point out the highlights and lowlights of each of them with
recomandation e.g. learning curve, development tools, ports etc.

Thank,
Ram
