Fast Mode: the problem of this mode is when your system reboot or halt you will need to configure again, but you configure four UART wires in J990. Using user space to configure mux and disable bluetooth. Default kernel&nbsp; has disabled TWL4030 PCM voice interface output pins to high impedance, otherwise this module forces the level of mcbsp3_fsx and mcbsp3_clkx pins. To make sure, go to ~/sound/soc/codecs/twl4030.c file already read: <br>

<pre> 0x04, /* REG_VOICE_IF (0xF) */</pre>

=== Configure IGEP ===

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

</pre>

Mode will be 1 (uart mode)
