Maybe of interest?Yes, this looks good -- both the AT91SAM7X line and FreeRTOS. The problem is, I can't find the SAM7X line anywhere, and Atmel's website says the product status is "sampling". How/where did you get you get your hands on it? Thanks, -- Randall

In fact, the origin of Nut/OS had been Liquorice (by Dave Hudson, available at SourceForge), which got LGPL. Every code we wrote had been published under BSDL. Some parts had been taken from BSD itself or from public domain code (good ol' TCP/IP days). Nut/OS links to platform libraries like avrlib-c, which are either LGPL or BSDL. Some of the tools, like the wxWidget based Configurator, are indeed GPLed and I recently decided to publish other tools under the same licence. None of these will be required in the final system. Nut/OS is used in a number of commercial products, a few of them are listed at http://www.ethernut.de/en/community/appliances.html But in general you're right. One should carefully check the licence requirements before using Open Source for embedded systems. Harald
