LS1012a how to make pfe.ko built in to kernel

[dchin]

I want to build in to the kernel the pfe.ko module instead of using it as a LKM for the LS1012a, is there any issue in doing this, and how do I do this?

Hello Dale Chin,

It is impossible to build pfe.ko into Linux Kernel.

Let me explain the challenge we have to make pfe as built-in kernel module.

Currently we have two different PFE firmwares for U-Boot and Linux. On Linux boot, PFE driver gets the PFE-linux firmware from /lib/firmware which will be available after rootfs is mounted. 

One way we see to resolve this issue is to use the same PFE firmware for both U-Boot and Linux. This is something that has to be worked out.

This is a new feature, not supported in LSDK 20.04 release, it will be supported in the future.

Thanks,

Yiping
