Disable i.MX6 UART from user application?

[chris_f]

I'd like to force both TX and RX pins of a UART to zero volts while I cycle the power of an attached peripheral. Is it possible to do this from a user application?

Hi Chris,

From user applications, UART could be used as resources that could be locked or released. If you want to enable/disable them, and/or force logical levels on pins, you should use kernel operations and/or modified drivers to implement these functionalities.

Hope this will be useful for you.
Best regards!
