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.
