eCOS and/or FreeRTOS experience?

Development Boards MicroMod

Does anyone out there have direct positive or negative experience with either FreeRTOS or eCOS on LPC or AT91? I’ve read up on both of them at their respective websites, so please restrict flames and praise to direct experience :slight_smile:

Thanks,

I have a version of FreeRTOS working on the Olimex LPC2148 board. It seems to work quite well, but I’ve not gotten further than basic UART communication and some button testing.

You should find plenty of relevant stuff on the LPC2000 Yahoo group.

FarMcKon where have you downloaded the software for freertos on a lpc2148.

I downloaded my project from the LPC2000 Yahoo group, Files section, FreeRTOS directory the file is lpc2148_freertos.zip. The URL below is the direct URL to that directory and will require you to log in.

http://tech.groups.yahoo.com/group/lpc2 … /FreeRTOS/

NOTE: It didn’t compile off the bat for me. I use sdk4arm, and it had GCC version differences. I merged my changes and a coworkers eariler LPC2148 version to get it to compile. It was mostly Makefile changes. But the vast majority of what you need is right there.

eCos LPC2294 stuff

Recently I made 3 eCos ports for LPC2294 based boards from

Olimex. These targets are Olimex LPC-H2294 header board, Olimex

LPC-E2294 and Olimex LPC-L2294-1M development board. Sorry, but

it isn’t a part of eCos anon. cvs yet, but all of them are living

here still: http://sgs.gomel.by/sg.

eCos AT91 stuff

As I known a set of the AT91 based boards are supported by eCos

community. Nowadays, these targets presents in eCos anon CVS: Atmel

evaluation board (EB40), Atmel Diopsis evaluation board (jtst),

Atmel AT91SAM7SEK evaluation board, Atmel AT91SAM7XEK evaluation

board, Atmel evaluation board (EB40A), Atmel evaluation board

(EB42), Atmel evaluation board (EB55), PHYTEC evaluation board

(phyCORE AT91M55800A).

Hi,

I’m sorry, for double post, but if you saw the Apache’s ‘Not Found’

message, be sure, that dot in ‘sg.’ URL wasn’t a part of the URL,

but it was a part of punctuation. I noticed that did become a real

catch for the clickers. So, that URL must be http://sgs.gomel.by/sg

and slash-dot :wink:

I grabbed sashi_oni’s FreeRTOS for LPC2148 off of the Yahoo! LPC2000 group files, and reconfigured it to compile with GCC/Eclipse (it was previously for Keil). It was simple work, but it may help out someone new to get the package in a ‘unzip and compile’ state. You can grab it at this page:

I hope to update it a bit, but I will probably concentrate on making a ‘demo’ for the LPC2148 from the most current branch.
