Disable automatic activation of Wifi and Bluetooth drivers from kernel

[IvanMC]

Hi, I'm working with an armbian installed on a Banana Pi M2S and I'm having problems using GPIOX_12, GPIOX_13 and GPIOX_4, because the Wifi/Bluetooth drivers are introducing garbage data by default into them and making it difficult to use them for communication in my project.

I need to know how to disable these drivers from the kernel so that they don't interfere with the UART communication that I'm creating on those pins, since they are enabled by default and take control of the port automatically (even without having any module connected).

 

Question:

• Is there any way to disable them in the kernel during the image building process?

 

For the moment I won't use those drivers since I'll be installing a Wifi module via USB later.

 

I'm building the armbian image from the repository using these build variables:

./compile.sh build BOARD=bananapim2s BRANCH=current BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=no RELEASE=jammy EXTENSIONS=preset-firstrun

 

Any help or pointers would be very appreciated.

Thank you very much in advance!
