E-COS development

Linux != eCos. They are very very different.

eCos is associated with linux, usually, because it is currently owned by Redhat.

So, are you wanting embedded linux advice or eCos advice?

We sell both Sciopta RTOS (very fast and small due to Assembler based kernel) as well as SMX (traditional C Kernel) - both offer support for ARM and a wide variety of processors. BSP's are included at no cost.

Contact me at: snipped-for-privacy@emRep.com and I can share more details with you. Eric

Linux is too heavyweight for an AT91-based system (yes, I'm sure someone will argue with me). Anyway the AT91s [that I know] do not have MMUs, so you would be using ucLinux, not "real" Linux.

eCos is a completely unrelated operating system. I would describe it as very well suited to your type of application - it is lightweight and highly configurable, and has a very functional TCP/IP stack. And it is free.

Im pretty sure that 2.6 kernel supports MMU-less processors...

There is the AT91RM9200, ARM 920T, 180 MHz with MMU and "real" Linux downloadable from Atmel's web site. And the part is real, we're working with prototype boards right now, although we're not using Linux.

So it is time to learn about the AT91RM9200 Lewin ;-) (Has a USB host controller as well !)

Fair enough. When people talk about Atmel's AT91 series, they usually seem to be talking about the ARM7 beasts, though, which is why I made the assumption.

Yes - basically, the key kernel patches of ucLinux have been merged into the main tree in 2.6.

Thank you for the indications about e-cos. Do you know about some hi-level development environments that are compatible with e-cos (compiler, debugger, etc.)?

debugger,

The standard tools are the gnu development tools. That means gcc as your compiler (for c, c++, ada, or whatever), and gdb as the debugger (using Insight, gvd, ddd or whatever for a front-end gui). I guess it's possible to use other tools, but I don't know.

There are rumors of one guy who got eCos built for some oddball platform using something other than gcc, but for all of the common architectures, gnu is the only practical choice. If you want a pointy-clicky IDE, there are quite a few to choose from (KDevelop, CodeWarrior, etc.)
