Hello,
I am using SYSBIOS with CCS6.0. I am kicking off Timer0 to start running before I enter BIOS_start();. I then generate a Timer0 Hwi every 62.5 usec. I simply toggle a GPIO pin and then run a small Swi routine. The problem that I am seeing is that every 8 seconds or so the timing gets slightly disrupted. My oscope can't trigger the waveform, so it will start to jitter. Then everything goes back to normal, the waveform is solid and everything works great. 8 seconds later I see the jitter again. The waveform will start slightly too early or slightly too late. Then it will get back on track. Could there be a SYSBIOS thread that is running at a higher priority than my Timer0 Hwi? What do you think is causing this?
Thanks,
Rick
