To test UARTs we use UART0 (dev/ttyS0) and UART3 (dev/ttyS2) via J960 connector.
By default, UART0 is used by RS485 driver, we need to disable RS485 support, go to igep.ini file and search line:<pre>board.ei485= yes</pre>Maybe you don't fond this line, replace by or type this:<pre>board.ei485= no</pre>By default, UART3 is used by Kernel serial console, we need to disable it, go to igep.ini file and comment next line:<pre>console=ttyS2,115200n8</pre> === Check UARTs devices<br> === === Check UARTs devices ===
