I bought a Chinese clone from Bangood.
The item comes with the GPS Serial port broken.
I am trying to remap the serial device used internally to anothe unused serial port.
I found some post sharing sucess stories about this:
but I am wondering if there is a easy way without modifing the firmware:
As everyone knows the init rcS script call for a script in the SDCard:
47 # Look for an init script on the microSD card.
48 # Disable autostart if the script found.
50 set FRC /fs/microsd/etc/rc.txt
51 if [ -f $FRC ]
53 echo “INFO [init] Executing script: $FRC”
54 sh $FRC
55 set MODE custom
My question is: Is it posible to rename de TTY device at the boot time with a config file in the SD Card like this?
mv /dev/ttyS3 /dev/ttyS20
mv /dev/ttyS4 /dev/ttyS3
mv /dev/ttyS20 /dev/ttyS4
