I just looked through the
Robot Rules, the only official source for this year. I could not find a minimum required firmware version for the PDP. There are multiple firmware versions required for other items:
Talon SRX: 0.28 or newer if using via PWM (R34 part A section vi)
If using CAN: Grey Jaguars: v109, Black Jaguars: v109, Talon SRX – v1.01 (R75)
PCM: 1.62 (R76)
arjunanand23 - Can you please find where you got that information from for us?
