Hi Josh1745,
You can only access pwmchip0 (@7000a000).
pwmchip4(@70110000) is not expected to be used by user.
“The Pulse Width Modulator controller is a four channel frequency divider whose pulse width varies. Each channel has a programmable frequency divider and a programmable pulse width generator”
As per the above statement, individual 4 channels of pwm@pwmchip0 can be used (based on availability) by exporting them.
i.e. echo <0/1/2/3> > /sys/class/pwm/pwmchip0/export
Please try with above and let us know what problem do you face on your configuration.
Thanks & Regards,
Sandipan
