Tool/software: Linux
I am using ubuntu-16.04.3-minimal-armhf-2017-10-10 on my bb-x15.And some questions occured when developing CAN .
1.According to the user guide:
every thing is good , but I can't set ctrlmode tripple-sampling on using cammand :canconfig can0 ctrlmode tripple-sampling on
can0 ctrlmode: loopback[OFF], listen-only[OFF], tripple-sampling[OFF],one-shot[OFF], berr-reporting[OFF]
2.I have check the pinmux register value and connect the dcan1_txd to dcan1_rxd for quick test. But It's not working,(I use command cansend &candump ),it looked like candump is blocked and I supposed dcan1_rxd receive nothing .
