Which system do you use? Android, Ubuntu, OOWOW or others?

Android 14

Which version of system do you use? Please provide the version of the system here:

Android 14 build according the khasdas vim release doc

Please describe your issue below:

I want to use the pin 15/16 for the UART_C and determine which is the UART_A

The old forum post: I want to use uart in Android - #5 by Terry
says it should be the ttySX, but no ttySX at all, also I checked the post : VIM3/3L UART [Khadas Docs]

only the ttyAMLx exists:

console:/ # ls /dev/tty*                                                       
/dev/tty  /dev/ttyAML0  /dev/ttyAML6  /dev/ttyAML7  /dev/ttynull

Which one is the UART_c and UART_a? What is physical uart for the ttyAML0 ?
