Kernel 4.1.15 Can only compile the driver as a module but not into the kernel? #170

Kernel 4.1.15 I loaded the driver as a module and it was perfect. I tried to select "*" to write the kernel and compile it together, but it was not recognized after being burned into the board.

If you want the driver to be built into the kernel, you would need to merge the code with kernel source, probably in the drivers/staging tree. All statements involving #LINUX_VERSION_CODE would need to be simplified so that only the code appropriate for your kernel is left. Finally, you would need to write a Kconfig and Makefile suitable for kernel building. It would take an expert about 10 hours to complete that. I suggest you find out how to add an external module to your system. That would be a lot easier.

Thank you very much for your attention.

I will automatically load this driver according to modules

Edit loading file

vi /etc/modules

8723bu

Add kernel file boot

mkdir -p /lib/modules/$(uname -r)/kernel/drivers/net/
cp 8723bu.ko /lib/modules/$(uname -r)/kernel/drivers/net/

Generate module load file

cp kernel/modules.builtin /lib/modules/$(uname -r)/kernel
cp kernel/modules.order /lib/modules/$(uname -r)/kernel
depmod -a

But I have another problem

The drive speed provided by the original factory can reach nearly 10M/s.

Test

Using your drive is much slower 2M/s

That I cannot help you with. I did not write the driver - I only provide the factory driver here in a form that will build. I do not understand the details of the chip! Sorry.
