MPC5746 FlexCAN7 do not work

[jackchow]

          Hi ,I meet an qustion about flexcan. in the case,MPC5746C support 8*FlexCAN.CAN0~CAN6 are ok，but CAN7 do not work.Measurement of GPIO(CAN7TX, PG2)  has no waveform.  CAN7 and CAN0~CAN6 peripheral circuit are the same.

         Does the MPC5746 need special configuration for CAN7？thanks!

Hello,

I checked FlexCAN7 module and it works correct on my side. Could you please send me your CAN settings and GPIO settings?

Also, could you please write me, which mask and package of the microcontroller you use?

Regards,

Martin
