I need to enable the UART pins on UEXT.
I don't know what I do it.
I have this devices list
autofs rtc0 tty42
bus/ shm/ tty43
char/ snd/ tty44
console stderr tty45
core stdin tty46
cpu_dma_latency stdout tty47
crypto tty tty48
dcpboot tty0 tty49
fb0 tty1 tty5
fd/ tty10 tty50
full tty11 tty51
fuse tty12 tty52
i2c-0 tty13 tty53
initctl tty14 tty54
input/ tty15 tty55
kmem tty16 tty56
kmsg tty17 tty57
log tty18 tty58
loop0 tty19 tty59
loop1 tty2 tty6
loop2 tty20 tty60
loop3 tty21 tty61
loop4 tty22 tty62
loop5 tty23 tty63
loop6 tty24 tty7
loop7 tty25 tty8
mem tty26 tty9
mmcblk0 tty27 ttyAMA0
mmcblk0p1 tty28 ttySP1
mmcblk0p2 tty29 ttyUSB0
mmcblk0p3 tty3 ttyUSB1
mxs_viim tty30 urandom
network_latency tty31 usbdev1.1
network_throughput tty32 usbdev1.2
null tty33 usbdev1.3
psaux tty34 usbdev1.4
ptmx tty35 vcs
pts/ tty36 vcs1
ram0 tty37 vcs2
ram1 tty38 vcsa
ram2 tty39 vcsa1
ram3 tty4 vcsa2
random tty40 watchdog
rtc tty41 zero
The UART on UEXT is connected to AUART1 of iMX233.
What do you want to do with it? Use it for the terminal connection instead of the debug UART?

In case you want to use it from within your booted system. The extra UART is already available as the /dev/ttySP1 device.
Check out the example here:

Btw:
Taken from https://www.olimex.com/forum/index.php?topic=447.0
How about using search first?
I would like to use to connect external modules.
