Enabling the PPP on STM32MP1DK2 board

Hi.... there

Hope you all are doing well

From past few days, I'm playing with STM32MP1

I need to integrate the Quectel EG25G module with the image having ppp functionality

To do so, i have enable ppp support at Make-menuconfig and build the image

Now the problem is, after building the image from scratch, i haven't found the directory /etc/ppp

Even i have also try with the installation from apt-get

But unfortunately, it's not working

Any suggestions ?

Thanks
