Does eCos work on the LPC2104 ?

Started by smt5211 October 7, 2004

Hi,

I know that eCos works on the LPC2106, with 64Kb ram and 128Kb
flash. Does eCos work on the LPC2104, given that it only has 16Kb of
ram? We would need a JFFS2 file system to external flash.

Hi Shane,
Check out www.ecoscentric.com. I know that they are working on a range of
LPC2000 ports

Hello,

You will be able to work with eCos on LPC2104, but it is far from an
ideal sollution. You have to make restictions for thread stack sizes,
make a minimal configuration and you won't be able to use more than 2
or 3 threads. For an example my simple application that using 2
threads with 2048byte stack size (and of course with stack for idle
thread, and separate stack for ITs) uses about 20k of RAM so you
should make resticions for stack sizes above.

I'm not familiar with the JFFS2 file sytem so I'm unable to say
something about its resource requiments.
