 Posted: Sun Apr 12, 2020 8:10 pm Post subject: Linux firmware for iwlwifi ucode failed with error -2 |
 |
|
Hello everyone,
I'm trying to get Gentoo working on my machine, but every time I fail to get a working internet.
With the installation medium (official minimal from gentoo), no problem to be seen, everything works perfectly after a quick "net-setup".
But after the installation, I can't see my Wi-Fi card which is a "Intel 7265" (using ifconfig -a or ip addr).
I follow this page, set every option as module and install the Linux firmware.
After a bit of digging (with the dmesg command)
I've found this message : "iwlwifi 0000:03.0 Direct firmware load for iwlwifi-7265D-*.ucode failed with error -2", and at the end of the page I was following, there were a link for the same error.
But the solution seems to be "just set it as a module" and I've already done that so... I'm a bit lost if anyone could help me 
Thank you ! |

Speedflam,
Wild guess based on you did everything right but it doesn't work.
You are not running the kernel you think you are.
What is the time in
| Code: | $ uname -a
Linux NeddySeagoon_Static 5.6.0-gentoo #1 SMP PREEMPT Thu Apr 2 18:34:15 BST 2020 x86_64 AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux |
The Thu Apr 2 18:34:15 BST 2020 is the build time of my running kernel.
You look at your uname -a output and ask yourself it you have build a more recent kernel?
I'll guess you have but forgot to mount boot for the kernel install.

And you were wright, I wasn't using the last kernel I compile. I've mount the boot partition and re-install the kernel but nothing change. I still got the same message. |

Regarding 7265D there is a certain note. Does your linux-firmware version have the mentioned -29.ucode for 7265D?
Please also wgetpaste your kernel's .config so we could have a look |

Yes as you can see at line 701, it does.

Just to be absolutely sure, what is your output of | Code: | | ls -al /lib/firmware/iwlwifi-7265D* |

There was (or still is?) some trouble with newer kernel versions. Have you tried with 4.19.113 ? |

iwlwifi has been working long time for me working without setting this.
But it will be needed for different purpose. |

Sure, it's here
I downgrade to 4.19.113 and it works

Glad to read you got it solved. But you should also solve the microcode trouble (see "different purpose"). |

And I done so, in a very dirty way but I did it. Because I wasn't able to change this line :
| Code: | | CONFIG_EXTRA_FIRMWARE="" |
To this one :
| Code: | | CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" |
Using the "make menuconfig" command, I've edited the .config file with nano, even if it's clearly written "DO NOT EDIT THIS FILE" (sorry  )
Miraculesly it work, maybe it's due to the fact that I've switch to iwd instead of iw and wpa_supplicant, but now everything is working with a 5.4 kernel. |

For editing the lines in menuconfig, you have to have the cursor on that certain line, then hit ENTER.
That way you should get the line open for editing: https://i.imgur.com/dg9g8Bm.png |

The problem is that I need to install the driver the "built-in" way and enter first the "firmware blobs into the kernel binary" and then I can edit this line.( https://imgur.com/ynuFdW9) |
