I don't think the documentation says that.

It can be used. Mr. Denk is unhappy that we do not allow non-GPL use of RTLinux, RTLinux derived code, or the RTLinux patent without charge. > > As I understood I could choose to use the GPL for my programs, OR, make my > program as a module, and thus choose the license I want (fx. proprietary if > I want). This is not correct. While Linux kernel permits binary modules as an exception to GPL, most other GPL projects require that any derived code be released under GPL. > Further more, I was under the impression that RTLinux was released under the > GNU GPL and that this mean that IF I can get RTLinux to work with MPC823 I > am free to do so? \ Of course. As long as you follow GPL and the Open RTLinux Patent License. The only issues are when you seek to combine closed source code with RTLinux/GPL in which case, as with all such combinations of GPL and non-GPL code, it is wise to get legal advice. FSMLabs currently supports RTLinux/Pro for 8xx and welcomes contributions of RTLinux/GPL for 8xx. In fact, the major difficulty is not RTLinux, but a stable Linux for these processors. > > FMLabs, please clear this up, it seems kinda messy to me - is your code GPL > or not, can I use it with the processor (and kernel) I want to or can't I? > > > Hope it helps, > Thanks for your timing-results :) > > Did you get RTLinux to work with MPC823? > Have you continued to support RTAI, and is it working for you? > > Regards, > David Marqvar > -- [rtl] --- > To unsubscribe: > echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR > echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] > -- > For more information on Real-Time Linux see: > http://www.rtlinux.org/ -- --------------------------------------------------------- Victor Yodaiken Finite State Machine Labs: The RTLinux Company. www.fsmlabs.com www.rtlinux.com -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
