Cannot remove UART 'UARTX' from device tree; #8

Sorry for poor English

I'm using the libbulldog to control GPIO, such as LEDs and buzzer on Debian BeagleBone Black. in a simple test using the blik LED when terminate the application, the following message is displayed:

Can not remove UART 'UART5' from device tree; It will crash the bone

Can not remove UART 'UART4' from device tree; It will crash the bone.

These two serial UART must be enabled to be controlled via serial rxtx lib

The libbulldog locks all enabled serial UART, even not using them?

Hi lapavila,

you can safely ignore these warnings. UART will automatically be set up if requested, but won't be torn down. I'll just remove the messages from the next version of libbulldog.

libbulldog will do nothing to them, if you don't explicitly use the UARTs with the bulldog API.

Best regards, Datenheld.
