Software timer malfunction

Posted by Dirk on January 14, 2013

After I experienced a crazy behavior of the FreeRTOS software timers I did double check the "Known Issues with the Current Version" list and the "version change description" for an explanation. Because I did not found anything I started debugging my complex application because I was sure I did make a mistake within my code. After 2 days of debugging I found a serious bug at timers.c line 502 - prvProcessReceivedCommands() - that is present in all FreeRTOS versions >= 7.0.0. However after knowing now what to search for I recognize this bug was discovered by Greg Renda in november 2012 and acknowledged by Richard Barry.
It would be great if this issue would be set to the "Known Issues with the Current Version" list, may be with a link to the solution like this is done within "Coldfire V1 CodeWarrior port". That would be save a lot of time and diagnostic work for all users. Thank you.

Sorry I have omitted to list this issue. I believe it is fixed in the SVN head revision.

For future reference, when quoting a line number please also quote the version of FreeRTOS the line number relates to, and when referencing other posts please provide a link to the post (I searched for the name in the archive to find it).

Regards.
