Hello,

Yes, FlexCAN is verified on latest BSP.

The iMX8QXP defaul driver used CAN fd mode, so we used followed command to test it:

Rx: ip link set can0 up type can bitrate 1000000 dbitrate 4000000 fd on

Tx: ip link set can1 up type can bitrate 1000000 dbitrate 4000000 fd on

Rx: candump can0

Tx: cangen can1 -m

If you want to use the legacy mode iMX6/7 test command such as "ip link set can0 up type can bitrate 1000000", you need disable the fd mode in device tree by added "disable-fd-mode".

The CAN test code can be found.
