[SOLVED] LFS - direct firmware load failed error -2

nocrazy · 08-22-2016, 02:09 PM

Good evening,
When I start the eth0, it works.
However I get Direct firmware load for rtl_nic/rtl8168g-2.fw failed with error -2
I downloaded the firmware and dropped it into /lib/firmware/, still the same.

Any idea...

Please post the output of the following command:

Code:

ls /lib/firmware/rtl_nic

Also, if you built r8169 into kernel (not as a module) the firmware will not load because at the time kernel loads the root filesystem is not mounted yet.

It's best if I put it in the right directory /lib/firmware/rtl_nic

Now I don't get any more the failed message.

ls /lib/firmware/rtl_nic return rtl8168g-2.fw

But LFS is still using the r8169 driver and if I compile the kernel without this device option, then I have no eth0, rtl8168g-2.fw is not running.

Is that firmware for wifi device? as wired is working.

What do you mean by "rtl8168g-2.fw is not running"? How do you know this?
What do you mean by "I have no eth0"? How do you know this?

This is onboard wired NIC Realtek 8168, it works without firmware with kernel r8169 driver, but there is a firmware fix for 8168, kernel driver sees 8168 and tries to load the firmware. Thus, the r8169 kernel driver needs to be built as module, when built into kernel it won't have access to the firmware at the boot time as I explained in post #3 (and what apparently was ignored by OP).

I don't understand very well how to build as module.

I got the driver from realtek and did:
make clean modules
make install
depmod -a
modprobe r8169

now it's in /lib/modules/4.4.2/kernel/drivers/net/r8169.ko

But still not working

Also another question : is systemd a wrong choice ?

To build as a module <m>, instead of <*> which is built into kernel.

Code:

grep CONFIG_R8169 /boot/config-x.x.x

That will show what the driver is built as.

depmod -m ? deprecated

There is no need to download r8169 driver from Realtek, it is already in kernel. You can download r8168 from Realtek, it would be exact match (and it is not in kernel).

yes it's working from the kernel. Thank you.
I just need to have rtl_nic/rtl8168g-2.fw in /lib/firmware/rtl_nic to not have an error message.
Now I will look into the wifi
