odroid_c2 compile kernel for 0bda:f179 support

moreno_fabio · June 25, 2019 at 4:39 PM

Good Morning,
I have a wireless usb adapter with id 0bda: f179 and I would like to add the rtl8188fu module to it in the kernel.
I already compiled this module for the armbian on the c2 odroid and it worked correctly.

How should I compile this module in the kernel?

the following steps were taken:

git clone GitHub - LibreELEC/LibreELEC.tv: Just enough OS for KODI
cd LibreELEC.tv
git checkout libreelec-9.0
PROJECT = Amlogic DEVICE = Odroid_C2 ARCH = arm tools / download-tool

to compile the module in armbian I used following command
I downloaded the kernel-headers and then

git clone GitHub - ulli-kroll/rtl8188fu: rtl8188fu driver for linux
make
sudo modprobe cfg80211
insmod rtl8188fu.ko
make installfw

here is the cross compile command

make ARCH = "arm" CROSS_COMPILE = CROSS_COMPILE=aarch64-linux-gnu- KSRC = /usr/lib/linux-kernel-headers-3.14.79-116 modules

You will need to add a package to the build.

Add RTL8188FU to ADDITIONAL_DRIVERS in distributions/LibreELEC/options.

mkdir packages/linux-drivers/RTL8188FU

add package.mk to packages/linux-drivers/RTL8188FU (use package.mk from another RTL driver as a reference)

PROJECT = Amlogic DEVICE = Odroid_C2 ARCH = arm scripts/build RTL8188FU (or PROJECT = Amlogic DEVICE = Odroid_C2 ARCH = arm make image)

thanks.

is compiling
When I finish, I'll let you know if it worked.

**smp** · June 25, 2019 at 6:43 PM

You will also need this patch. Copy it to packages/linux-drivers/RTL8188FU/patches

moreno_fabio · June 25, 2019 at 7:16 PM

I compiled and generated the image but it did not work
when I rebooted the odroid appeared only a black screen.

should I recompile with this patch?
if I compile only the driver and install in libreelec already ready how should I do?

moreno_fabio · June 25, 2019 at 7:23 PM

Code

I downloaded the patch and put it in the folder so I tried to compile only the module with the command

PROJECT = Amlogic DEVICE = Odroid_C2 ARCH = arm scripts / build RTL8188FU

Returns
Incorrect checksum calculated on downloaded file: got 820f99039dcd499fa5c87fb371d37e7bac64ab1fb5a532af64bb3180db36160b wanted b51c1c4e8fb1d16fa628337346b32128524c78fc29964d7983959470feff86e4

How do I check checksum?
I downloaded tar from the package so I rode sha256sum on my linux and entered the value in the package.mk

**smp** · June 25, 2019 at 7:30 PM

You can remove the PKG_SHA256 line from package.mk

Without that patch it will not compile with kernel 3.14

moreno_fabio · June 25, 2019 at 7:33 PM

compiled and generated the following files How do I install libreelec?

/build.LibreELEC-Odroid_C2.arm-9.0-devel/RTL8188FU-fab4f5db4580d9a920f99c64dceaa5711589559d$ ls

moreno_fabio · June 25, 2019 at 9:00 PM

after compiling again with the patch I did the update of the image through tar libreelec started but the module did not appear

**smp** · June 25, 2019 at 9:02 PM

Did you add it to distributions/LibreELEC/options?

moreno_fabio · June 25, 2019 at 9:20 PM

yes

# additional drivers to install:

# for a list of additional drivers see packages/linux-drivers

# Space separated list is supported,

# e.g. ADDITIONAL_DRIVERS="DRIVER1 DRIVER2"

ADDITIONAL_DRIVERS="RTL8192CU RTL8192DU RTL8192EU RTL8188EU RTL8812AU RTL8188FU"

how can I install the module in libreelec without recompiling the complete system?

Add RTL8188FU to "ADDITIONAL_DRIVERS=" in projects/Amlogic/options

You can't. You have to compile a new image.

moreno_fabio · June 25, 2019 at 11:06 PM

Ok.

Thanks i will try again.

moreno_fabio · June 26, 2019 at 12:20 AM

Hi Can you share the package.mk file for rtl8188fu driver you used ? Thanks
