  Hello
  Thank you for this awsome low-cost development board.
  
  I am trying to run 4G hat with PPPD support i was able to enable serial port using
  luckfox-config > ttyS4 > enable
  
  Then i used a chat script named it rnet
  

  Code: Select all

  #imis/internet is the apn for idea connection
  connect "/usr/sbin/chat -v -f /etc/chatscripts/gprs -T airtelgprs.com"
  
  # For Raspberry Pi3 use /dev/ttyAMA0 as the communication port:
  /dev/ttyS0
  # Baudrate
  #921600
  115200
  # Assumes that your IP address is allocated dynamically by the ISP.
  noipdefault
  debug
  # Try to get the name server addresses from the ISP.
  usepeerdns
  
  # Use this connection as the default route to the internet.
  defaultroute
  
  # Makes PPPD "dial again" when the connection is lost.
  persist
  
  # Do not ask the remote to authenticate.
  noauth
  
  # No hardware flow control on the serial link with GSM Modem
  nocrtscts
  
  # No modem control lines with GSM Modem
  local

  Then ran these commands and this happends
  

  Code: Select all

  pico@luckfox:~$ pppd call gprs
  Couldn't open the /dev/ppp device: No such file or directory
  pppd: You need to create the /dev/ppp device node by
  executing the following command as root:
          mknod /dev/ppp c 108 0
  
  pico@luckfox:~$ mknod /dev/ppp c 108 0
  mknod: /dev/ppp: Permission denied
  pico@luckfox:~$ sudo mknod /dev/ppp c 108 0
  [sudo] password for pico:
  pico@luckfox:~$ pon rnet
  Couldn't open the /dev/ppp device: No such device or address
  pppd: Please load the ppp_generic kernel module.
  

  I am using ubantu version since buildroot version does not have any pppd directory
