Beagle-X15 drive DCAN1 in PRU

I tried to drive DCAN1 in the PRU, but I found that I could not change the configuration directly through the address mapped DCAN1_CTL register. Has anyone tried to use PRU to drive DCAN1? The DCAN1_CTL_REG always return 0x00000000.


I can not access the DCAN1_CTL register and set the DCAN1 to INIT mode.
