1Mb CAN bus with i.MX7Dual rev 1.3

[urimashiach]

Hello,

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?

Thanks,

Uri

Hi Igor,

I'm able to test the flexcan.

The problem is the rate of 1Mbit with i.MX7Dual rev 1.3.

Thanks,

Uri
