i was trying to get EPWMSYNCO signal out through GPIO-33,it doesnot work

i using this sync signal for my 3 internal pwms and i also need it for external functions

i just enabled it through GPIO MUX i.e GPBMUX1

anything else should i do,or does any body has used it before

Muhammad,

What ePWM modules are you using and what SYNCO signal are you trying to output? The only SYNCO signal that is tied to the GPIO MUX is from the ePWM1 module. If you are not outputting the SYNCO from ePWM1 then this is not going to work.

i am using ePWM 1 as master and ePWM 2,4,5 as slave using sync from 1 and it works internally but i got logic high on SYNCO ,and i have corectly configured GPABMUX as well,is there any thing left

so actually i found the problem

i was configuring the GPIO mux with out the EALLOW and EDIS statement

thanks to all of you guys for help

Muhammad,

I am facing the same problem. I have selected the SYNCO from GPMux for GPIO33. I did use EALLOW and EDIS while doing this.

I see a logic low. No pulse.

Any suggestions?

Thanks !

Amit.
