Tool/software:
Dear TI Experts,
In one of the tickets I posted, I am asking for information on how to configure DMASS, specifically BCDMA, to react to a Timer/PWM signal. Since the PWM on DMTIMER0 appears to be configured correctly (as I can see the output toggling) and DMASS is also correctly configured (software triggering works), I have concluded that, for some reason, the trigger signal from DMTIMER0 does not reach DMASS GlobalTrigger0.
In the mentioned ticket, I have already posted the registers' contents for the Time Sync Router and DMASS's L2G. My question here is: is there a way to trace where the interrupt request (IR) is getting lost? I suspect one (or more) of the following issues:
- The PWM IR from DMTIMER0 does not reach the TSR.
- The TSR does not correctly route the PWM IR to its LocalEvent Output[0].
- The L2G does not correctly map the TSR output to be used as GlobalEvent0 for the respective BCDMA channel.
Is there a way to check the IR state at the different input/output points?
Thanks and regards,
Angel Gavrailov
