Dear my friends,
I am using TMS320F28335 as the main controller in EV driver, I have a problem when I am doing the CAN bus off test ,when I recovery the bus line , sometimes(nearly 20%), ODB give the diagnostics command through CAN bus to controller, there is no any reply from 28335, but the other part run normally, and I finally found that when I change RANDWAIT and PAGEWAIT of FBANKWAIT Register from 5(default) to 10, the CAN communication recovery normal,
so I want to how to explain this, anybody knows if I change the RANDWAIT and PAGEWAIT more bigger, what happened in MCU internal(system and other peripheral)? just change Flash wait cycle?
