I'm using 1Mbit CAN bus with i.MX7Dual.


1Mbit communication is not functional with SOC revision 1.3.

Problem description:

  • Only the transmission  side is affected, listen only mode is functional.
  • Lower speeds are functional.
  • The problem is not detected with SOC revision 1.2.
  • Relevant pin-mux configuration:

            MX7D_PAD_I2C3_SCL__FLEXCAN2_RX        0x59
            MX7D_PAD_I2C3_SDA__FLEXCAN2_TX        0x59


Is it a know issue?
