nrf5340 audio dk hci_uart sample and VCOM

[chelalv]

I am using nrf5340 audio DK. After plugging it into the computer, 3 VCOMs and RTT will appear. What are these three ports?
docs.nordicsemi.com/.../logging_nrf5340.html Here is the nrf5340 DK

Why can other programs sysbuild compile two hex, one application mcu and one network mcu, but hci uart only has one application mcu?

Simple solution: Click on  "build" above the marked hci_uart_1 entry and then on the build button.
