Jetson nx : can configuration

[patrick.gouhier]

Hi,
The equipment connected on the other side is using a bitrate of 500000 (and we cannot change it ;) ) , so maybe we need to use pallon as clock source for nx ?

Controller Area Network (CAN) on Xavier NX at 1Mbps

Hi everyone, To achieve exact 1Mbps: Here is the documentation available to change CAN parent clock to PLLAON. https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fclocks.html%23wwpID0E06B0HA Check “ To use PLLAON as clock source” section With PLLAON, users will be able to achieve 50MHz CAN core clock rate and 1Mbps exact bitrate settings as well. To set 40MHz clock rate, I just replied in this thread, please check it out. T…

By the way, could you confirm the pin number associated to J17 port ? (sudo busybox devmem 0x0c303000 32 0x0000c400 sudo busybox devmem 0x0c303008 32 0x0000c458)
