Hi,

I am using iMX6Q with has Flexcan Controller, I have some questions :
First, correct me if I am wrong, CAN FD is not supported in iMX6Q (according to this Which processor supports CAN-FD in i.MX6 series?)

However, since the iMX6Q is using Flexcan Controller FlexCAN Controller|NXP, which support "Full implementation of CAN FD", why does iMX6Q not support CAN FD ? Is it hardware limitation ?

Also, what is the upper limit for filters that can be applied using Flexcan linux driver ?

Thanks

Hi Vijay

>why does iMX6Q not support CAN FD ? Is it hardware limitation ?

yes

could you clarify question as there are many "filters" description in Reference Manual.

Just for reference attached Linux Manual Chapter 37 FlexCAN Driver gives description of

flexcan driver.

Best regards
igor
