UIO-4030 Function
Note：
Device：ttymxc0 - COM_3, ttyUSB0 - COM_4(RS-485)
Need one Adam-4520I module for RS-485.
The test method is as follows
RS-232 U-boot setting：
u-boot=> setenv uart_mode 2:0 u-boot=> saveenv Saving Environment to MMC... Writing to MMC(2)... OK u-boot=> reset
RS-232（COM_3）
# stty -F /dev/ttymxc0 -echo -onlcr 115200 # cat /dev/ttymxc0 & [1] 653 # echo "Serial Port Test" > /dev/ttymxc0 Serial Port Test
CN3_GPIO
for example：Short GPIO pin1(in) 151 & pin6(out) 141
# echo 150 > /sys/class/gpio/export # echo 141 > /sys/class/gpio/export # echo in > /sys/class/gpio/gpio1/direction # echo out > /sys/class/gpio/gpio2/direction # echo 1 > /sys/class/gpio/gpio2/value # cat /sys/class/gpio/gpio1/value 0 # cat /sys/class/gpio/gpio2/value 1
RS-485
RS-485 U-boot Setting：
RS-485（COM4_）:
# stty -F /dev/ttyUSB0 speed 115200 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke # cat /dev/ttyUSB0 & # echo "Serial Test" > /dev/ttyUSB0
