How Enable CAN0 and CAN1 Bus on Jetson Xavier? Jetpack 4.6 and higher

[makwiatkow]

Hi, I have problem with CAN Bus on Jetson Xavier NX. I use this tutorial:

https://github.com/hmxf/can_xavier

My jetpack 4.6 but I try on 5.0 to.
When I test loopback:

sudo ip link set can0 type can bitrate 1000000 loopback on

Then trasmision work, but when i try connect pin29 to 31pin, and phisic send messag, than nothing happend.

I thik it is problem with configuration pin. How can I enableCAN0 on pin 29 and 31 or enable CAN1?
My CAN massage work Fine. I have oscyloskop.

I found post with similar problem:

Update the device-tree for CAN-BUS, PLLAON Clock

Ok, after a new attempt it works on JetPack 4.6. The clock is set to pllaon when I activate the mttcan with modprobe. The last thing I did was indeed the good strategy but I must have mess-up one of my dts file, hence causing the freeze of the kernel. (maybe I took one from an other version of JetPack accidentally due to a bad copy paste) For those who have issue using the can on the Jetson Xavier AGX, JetPack 4.6 here is my solution. Download with the sdkmanager the JetPack 4.6 but flash the…

But I dont know how compile db file. New SDK manager have One jetpack 5.0.
I try write image OS with jetpack 4.4 on my jetson. But get black screen. I use window Etcher to write image.
Next week I try install image on Linux.

Mayby samo One have working Image with CAN BUS? Jetson Xavier NX
