Flexcan in IMX8QM

[vinothkumars]

Hi All,

In IMX8QM-MEK have Base Board and GPIO-EXPANDER is there for CAN.

But, In IMX8QM custom board we don't have Base board as well as GPIO EXPANDAR, So, I removed theses gpio expander in rear_view_camera but Flex-CAN still not working.

Will you please give me some advice which area do I needs to configure.

Thank you @igorpadykov for the quick reply.

I am using SDK 2.5.1 from this SDK CAN used the io expander. But, my custom board don't have the io expander (BOARD_ConfigureExpansionIO) and I removed it from the flexcan driver. But, still flexcan is not working.

Please find the driver file used in sdk.
