I am running FreeRTOS 8.2.2 on MSP430F5529LP.
I created a software timer as instructed in the timer example document, with interval of 1 second.
My CPU tick is WDT, frequency is 512Hz.
In timer callback, I simply toggle red LED every second.
The LED toggles correctly after reset, but after a few minutes, LED stopped blinking.
Other independent tasks ran correctly at the same time.
There was an issue discovered that was introduced in V8.2.2, but is fixed in V8.2.3 - see http://www.FreeRTOS.org/History.txt
