rs232 active?
#1
Hi i have  LM5p2-DR 

HW: LM5 M4 (imx6) SW: 20211215

i am attempting to use the rs232 port, '/dev/RS232'  when i navigate to the utilities, system status, serial ports,  only /dev/RS485-1 and  /dev/RS485-2 are showing?

i should have  /dev/RS485-1,  /dev/RS485-2,  /dev/RS485-3  /dev/RS232 ??

is there anything to enable or configure to use the RS232 port, i have tried the below code, or maybe i have something else wrong?


Code:
port = serial.open('/dev/RS232', { baudrate = 9600, parity = 'even', duplex = 'full' })
log(port)


but port is always nil so i assume  '/dev/RS232' never is opened?

x = io.exists('/dev/RS485-1')
x returns true

but x = io.exists('/dev/RS232')
x returns false

Wrong firmware. You need to install LM5 Lite + Ext.
