Hi,
I have CAN bus working fine in jetpack 4.4 but it is not working in 4.6 (latest). After some searching I suspect that is due to a clock issue.
This is the output of the sudo cat /sys/kernel/debug/bpmp/debug/clk/clk_tree
below are some comparisons before enabling pinmux, drivers, interface etc and after for both jetpack versions in question.
4.6 [Not working]
[4.4 Working]
To be honest after enabling there doesn’t seem to be much difference (as far as I understand unless the osc bpmp value 14 to 15
is the deal breaker). Under these circumstances do you think updating the clock source will fix my problems?
Cheers,
Ganindu.
