'''Enable UART2 in J990:'''

signals: mcbsp3_dr | uart2_rts | NA | NA | gpio_141 | hsusb3_tll_data5 | NA | safe_mode

root@localhost:/sys/kernel/debug/omap_mux#

</pre>Mode will be 1 (uart mode)

=== Test UART2 in J990<br> ===

Connect UART2_TX with UART2_RX. Use minicom to prove UART2 (/dev/ttyS1)&nbsp;:<br>

<pre>minicom -D /dev/ttyS1</pre>

If you write characters and see the echo on the screen, you configure well correctly UART.
