Please describe your issue below:

I have built and flash the android source in VIM3 which is working well but the pppd drivers are not working. I have built the 5.10 kernel made changes but that also didn’t work. Can anyone suggest any solution related to pppd drivers or CONFIG_PPP_ASYNC=y, CONFIG_PPP_SYNC_TTY=y drivers. How can I run these drivers.
Although these two driver CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=y has been added in kernel .config file when I build the kernel. but doesn’t work.

Post a console log of your issue below:
