→Configure UART1 and UART3 in IGEP with RS232 levels on J960 connector
=== Configure UART1 and UART3 in IGEP with RS232 levels on J960 connector ===
==== Edit igep.ini file ====
To test UARTs we use UART1 (dev/ttyO0) and UART3 (dev/ttyO2) via J960 connector using RS232 standard.
*UART1 can used by RS485 driver, we need to disable it, edit igep.ini file: <br> <pre>board.ei485= yes</pre> *UART1 is configured in RS232 driver, when igep line is replaced by (or type in -Maybe you don't found this line-):<br> <pre>board.ei485= no</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=ttyO2,115200n8
;console=ttyO</pre>
==== Edit igep.ini file ====
Getty program uses /dev/ttyO2 in IGEP Firmware, disable it modifying /dev/inittab file:
*Comment nest line:
<pre> #S:2345:respawn:/sbin/getty 115200 ttyO2</pre>
