According to the 1060RM setting the ERFCR will enable the Enhanced FIFO. However when I try to even read the register in the FLEXCAN example it throws a hard fault. When I tried it in my own application on a imxrt1062 I also get a hard fault at that register address. Needless to say I can't set it either.
So the question is, what is the cause of the issue and is Enhanced FIFO even enabled and the RM is incorrect?
