I had one problems developing on the nano:
On tx2, I can control clk by following commands:
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/state
echo x > /sys/kernel/debug/bpmp/debug/clk/emc/rate
But,on jetson nano,I can’t find a directory to perform a similar operation to control the clock.(actually,i want to control cam2_mclk).
