    Not as part of anything that you submit for inclusion in RTEMS. <br>
    I don't know how this particular setup works. I can see host <br>
    utilities that you would just get from there and I don't know that<br>
    we care about those licenses. <br>
    <br>
    And there might be libraries you want to use with your experiments<br>
    that is GPL but not submit to RTEMS. That is OK if you manage how<br>
    it comes in contact with your own application code. <br>
    <br>
    Please avoid it wherever possible. If there is some run-time library<br>
    we need to ask for relicensing, then we can go that round. <br>

            At least it is a starting point. You can work with their<br>

            then just change the target.</div>
