Problem with connect with using UART

#1

Hello, Radxa community.

I have problem with uart connection. So i used yp-01 module (tty-usb) for connect with PC . In my case PC is server, which sent’s message to radxa 5c , but some how i can read it’s because i don’t see /dev/ttyS* . My scheme connection looks like rx_yp-01 -> tx_radxa_5c (UART2_TX_M0) , tx_yp-01 -> rx_radxa_5c (UART2_RX_M0 ) , gnd -> gnd .

Numeration of pinout

If you have any idea what wrong write me please:)

Thank you!

UART with adress /dev/ttyS2 can be opened with using rsetup utils in hardware section
