Hi,
I am working with MPC5777M EVM board for LIN protocol and for that I am configuring the GPIOs and shorting PC[9] and PC[11] pin using jumper.Find the GPIOs configuration in following attachment.After GPIO configuration I am trying to transmit data through LIN bus. But during the data transmission I found two error flag are getting set, those error flags are SZF(Stuck at Zero Flag) and BEF(Bit Error Flag). How to Fixed that error which set these error flags?
Is there external voltage is also required or not ? If it is necessary then on which GPIO pin or LIN connector port I have to give supply ?
Provide external 12V supply to active the transceiver and establish proper connection.
for supply 12V on MPC5777M EVM board make connection between the P3.1 and P3.2.
