Question, i.MX6SX CAN FIFO

SLICE — Mon, 17 Apr 2017 04:43:02 GMT

Dear team,

My customer saw that sometimes i.MX6SX cannot receive CAN data from external.

The phenomenon could occur on MCIMX6SX-SDB with Yocto 4.1.15_1.1.0.

The customer believes that i.MX6SX has 6bytes of RX FIFO buffer and it needs to be exceeded.

Could you show me how to increase the RX FIFO?

Thanks,

Miyamoto

Hi Miyamoto

RX FIFO is 6-deep defined by hardware and can not be changed by software,

according to sect.27.1.1 Block Diagram, sect.27.1.2 FLEXCAN Module Features i.MX6SX Reference Manual
