I am using UART0 (ttyHS0) in my Android app. I need another UART and want to make use of UART1 (ttyHSL0 if I am not mistaken) but it seems that it is already being used. How can I free up this UART so I can use it?
The UART1 (/dev/ttyHSL0) at pin11 and pin3 on the LS connector is used for the serial console purpose.
These are the information for using the serial console on DragonBoard 410C.
The serial console is very handy to login to the DragonBoard 410C.
I have not tried it but it maybe able to free it up by removing the following string from kernel option.
I wanted to avoid playing around in the kernel as I am still new to Android and Linux but this is as good a time as any to start learning. Thanks for the info.
