=== Configure IGEP ===

To test UARTs we use UART0 UART1 (dev/ttyS0) and UART3 (dev/ttyS2) via J960 connector using RS232 standard.

NOTE: Make sure that you installed open SSH server. If you don't have it go [[How to forge a local file system server with IGEP0020 board#Installing_Open_SSH_Server|here]].

By default, UART0 UART1 is used by RS485 driver, we need to disable RS485 support, edit igep.ini file: <br>

<pre>board.ei485= yes

</pre>

</pre>

By default, UART3 is used by Kernel serial console, we need to disable it, go to igep.ini file, comment next line: <br>

<pre>console=ttyS2,115200n8</pre>  

=== Check UARTs devices ===
