[Answered] Can we call rmt_driver_uninstall without having previously called driver_install?

[kolban]

In my current design, I have a need to allow the user to dynamically configure an RMT channel. I can perform the configuration and then call rmt_driver_install() to install the driver. I'll be honest, I don't fully understand what that means ... but anyway ... this question asks "Can I safely call rmt_uninstall_driver" against a channel even if there has been no previous "rmt_install_driver" against that channel? I am trying to determine whether or not I need to maintain a state/history table so that my code has to remember initialization state or can I leave it to the ESP32 to maintain that state on my behalf.

At the moment, you can not. 'uninstall' function dereferences the pointer to the per-channel configuration structure which is allocated in 'install' without checking it for NULL.
