v89 Jag used for CAN, trouble going back to PWM?

[heydowns]

We have several Black and gray jags that we've been using over CAN for a few weeks during build season. All of them are loaded with v89 firmware. Each Jag has its own non-default (not 1) CAN id assigned using bdc-comm.

We decided during competition to move one of our Black jags back to PWM by removing all connections from the CAN ports and making appropriate adjustments to the other CAN-connected Jags to properly terminate their CAN bus, etc, then hooking up a PWM cable to the Jag and digital sidecar.

We changed our user program to use the PWM-based Jag driver with appropriate PWM port number.

However, the PWM Jag does not seem to want to respond to PWM commands at all. It does get a valid pwm signal as the Jag LED goes to solid orange, but no matter what PWM value we send, it sits at neutral.
Plugging the same PWM line into a gray Jag we'd never used for CAN and never updated firmware on results in normal, expected operation so we do know that our user program is driving the PWM signal properly for non-neutral operation.

Unfortunately, as competitions go a lot of time for debugging was not available. We went back to CAN, changed the code, and everything was fine.


Looking for some feedback from other teams here:

Is anyone using a v89 Jag successfully with PWM connection?
If so, have you ever used that Jag with CAN prior?
I know some of the TI guys are lurking -- does the firmware require any settings changed to go back to PWM? Particularly, does it require resetting the id back to 1 or anything along those lines?
