Hello, I looked at the example code for CORTEX_ML3S series boards. There are some files provided by Luminary Micro that state that: You may not combine this software with "viral" open-source software in order to form a larger program. Does that mean if I use that FreeRTOS port I am not allowed to release my code under the GPL? Is FreeRTOS license (GPL with exception) a "viral" open-source software? I want to work with this FreeRTOS port and provide my resulting program under the GPL so I’m a little bit confused. Thanks, Alex Full license text from FreeRTOSDemoCommondriversLuminaryMicroethernet.h: // Copyright (c) 2006-2008 Luminary Micro, Inc.

I have previously asked Luminary Micro for a clarification on this point. What it means is you must not provide your code under an open source license that could cause the Luminary Micro libraries to also be covered by that license. It is my understanding that if you are providing your software as source code then this could not happen. If you are providing your software as a statically linked binary under a GPL like license then everything in the binary would be covered by the GPL (the exception in the FreeRTOS license is there to prevent this, so this is NOT true for FreeRTOS binaries). Please do not take this as any form of legal advice, just a statement of my personal understanding. You best approach is to contact somebody from Luminary Micro to explain your intention and ensure you are not doing anything that would breach their license terms. I think you will find Luminary to be co-operative. Regards.
