Flexcan Listen-only

Hi ,
I want to put my board flexcan in listen-only mode. Could you help tell us which bits are needed to place the Flexcan in listen-only mode? I'm using the i.MX6
These are the bits that will be enabled if I set the Flexcan to read-write mode in control register. 0011 0001 0010 0000 0000 0101 0011 0001 0011 0001
Similarly, if I use the IP Link command to enable the listen-only mode (ip link set can1 up type can bitrate 500000 listen-only on), these bits will be enabled in the control bit: 0000 0100 0011 0001 0010 0000 0000 1101.
I verified with this command (ip -d -s link show can1) to confirm that it was set to listen only.
However, if I send data from another board the data is not receiving and please let us know what could be the reason.
Regards,
Jamal Deen
