TDA4VM: The system can't automatically insmod the kernel module during the boot process.

Part Number: TDA4VM

Hi,

When we use the prebuild image of Linux Kernel provided by TI, the system have the ability to automatically insmod the Linux Module.

When we use the source code (board-support\linux-4.19.94) provided by TI to compile the Linux kernel,
and then we replace prebuild Linux kernel (boot\Image) on the sd card with the Linux kernel (arch/arm64/boot/Image) compiled by ourselves.

When the original Linux kernel is replaced, the function of automatic insmod disappears.
What could be the problem?

Below is our defconfig of Linux kernel, can you help us check what is missing?
