Hi! I am looking for a free Operation system that can be used for 8-bits CPU, AVR; I am using a card with Atmega 128 and CC2420. I will implement the IEEE 802.4.15 protocol stack but a need an OS that can take care of the stack. I have look on the Contiki by Adam Dunkel but is fully integrated with his TCP/IP stack so a need something else. Does anyone have some suggestions? Regards Ulf Reiman
OS for 8 bits processor

He recommended against it when I was shopping. In addition to the other's mentioned, there's XMK: http://www.shift-right.com/xmk/ I Haven't used it, but I was rather impressed after browsing the source code an documentation a while back. -- Grant Edwards grante Yow!

Not sure whom this friend is, but I can provide contact info of people specifically using CMX-TINY+ for the AVR and are very happy with it and some have tried or compared other OSes and we have won against them.

He said that the scheduler was written in "spaghetti" assembly language, and it wasn't fun to work on. I was surprised to hear that the scheduler was in assembly language -- I've worked with 4-5 RTOSes, and they were all written in C with a bit of assembly language for context save/restore. -- Grant Edwards grante Yow!
