I was also told by an Atmel app engineer that they are currently working with FreeRTOS to include a TCP/IP stack. Hopefully it's not the uIP
stack that is being featured in FreeRTOS.org.

In my original post, I'm interested in embedded RTOS.
FreeRTOS seems to be the only one I can find, but it
doesn't support nested interrupts.

I'm working on getting RedBoot and eCos up and running on the AT91SAM7 eval boards. Since this hardware is pretty new, I'm not aware of any software which is available yet.

Hi Oli,

Cool; I'm glad to see someone else is interested in this. I'd be interested in coordinating efforts. As we've both discovered, yes, Redboot can run; but there's not much room left over to do anything with, unfortunately.


I'm of the opinion that some useful Open Source software can be made which supports all of these microcontrollers.


I'll drop you some email shortly. If anyone else is interested, do speak up.

Hi

I'm also interested in bringing eCos up on the at91SAM7-EK board. I just got build tools installed and tested out by compiling the tree for the eb40 board which went smooth. Does anyone out there have a template already to import into the configtool for the SAM7 part or some hints on how I can create my own template as I am a newbie with these open source tools.

Thanks

Mike

Pros and Cons of RTOS'

Mon Aug 08, 2005 11:32 am

I'm Just starting up again with a few years break from uP's. It's all a bit daunting :? I'm going to use a AT91SAM7S64 -EK and I think it makes sense to us a RTOS. I see some of you guys are using/ developing these. Can you give advice
Which is best?
Which is easiest to start with, i.e. lots of demos and info.

From my search so far I see that FreeRTOS is available, it seems to handle multitasking and some IO but as far as i can see doesn't contain a FS or much peripheral control (or am I wrong?)

uC/OS-II seems to have a version for IAR and the EK, and here you can buy a FS module too. Has anyone got any experience of this on this device?

Otherwise I see you are discussing redboot and eCOS, what do they contain and how stable are they?


Hope someone can help :D
Thanks
Paul

Are you sure about nested ISR? :?:

Iam gonna start with developing a simple application in AT91SAM7x-EK board
using ecos

have read the document abt he ecos and its very tricky to understand ...

how to put the redboot working in the board
how to configure the ecos for AT91SAM7x-EK board and config the HAL

if any one has passed thi stage with ecos in a AT91SAM7x-EK board, then please give me some advice.

the cygwin , toolchain and ecos is setup in my host and seems to be correct

Hi,
Few days ago I tested FreeRTOS and the TN-Kernel for my new project on an AT91SAM7S256
--> http://www.tnkernel.com/
TN-Kernel seems to be a quite good RTOS. It has a rich set of synchronization primitives (like commercial RTOS have, I have some experience with embOS and CMX-RTX), unlike FreeRTOS, which has only queues that are used for everything :(

On targets such as AT91SAM7X-EK with only 64KiB system RAM, I would recommend the use of a JTAG debug adapter with eCos to avoid the memory overhead of RedBoot or GDB stubs.

BeRtos.org has a port for the SAM3X - I haven't tried it, but its on list to compare it against freeRTOS that is part of the framework :D .

I would recommend to take a look to Nuttx OS, it's more than a simple RTOS, it includes device drivers, networking, file system, c++ library, USB and graphic support.
