Instructions to Recompile Linux Kernel in IFC6640

[christian]

Hello,

I am looking for information/instructions on re-compiling the linux kernel for the IFC 6640 so I can enable additional modules.
Any help on this matter would be greatly appreciated.

Hi Christian,

Please refer the release notes. It has all the required instructions.

I need some help with the 6640 Inforce Board.

I have downloaded the BSP package version Inforce-IFC6640-AndroidBSP-880493-Rel-v3.1. Running the provided script fetchsrc_and_build.sh, I successfully built and flashed the generated images onto the inforce development board IFC6640-01-P1.
However, I now wish to perform several customizations on the supplied Linux kernel. In particular, I would like to:
• enable several additional modules (that are either NOT enabled) in the supplied running Linux Kernel that is part of the supplied BSP (Inforce-IFC6640-AndroidBSP-880493-Rel-v3.1).
• trim it further to fit our needs

Could tech support provide clear steps and guidelines on how to :
• modify the Linux kernel (via configuration files )
• rebuild and flash the modified kernel onto the IFC6640.
In particular, we would like to enable USB0 network interface in order to enable Ethernet communication over USB.

Hi Christian,

You can enable/disable what ever features you require in the device tree or in the config.

6601-M_7.1.1/kernel/msm-3.18/arch/arm64/boot/dts/qcom/msm8996.dtsi

or

6601-M_7.1.1/kernel/msm-3.18/arch/arm64/configs/msm_defconfig
6601-M_7.1.1/kernel/msm-3.18/arch/arm64/configs/msm-perf_defconfig

Hope this helps

Best Regards,
Ashwin
