Description

Adapter is recognized during the system boot, but doesn't show in the `ifconfig` output.
I have tried both compiling `iwm` in the kernel and adding it as a module in the loader.conf.
I'm running DragonFly 5.0.2-RELEASE on the ThinkPad X1 Carbon Gen4.

Dmesg shows the following errors:

iwm0: <Inter(R) Dual Band Wireless AC 8260> mem 0xe1000000-0xe1001fff at device 0.0 on pci4
iwm0: fw chunk addr 0x404000 len 712 failed to load
iwm0: iwm_pcie_load_section: Could not load the [0] uCode section
imw0: iwm_start_fw: failed 60
iwm0: Failed to start INIT ucode: 60

History

#1 Updated by hermez 8 months ago

Same thing on my Thinkpad T580, un dev version from Apr 18. 2018. Please see screenshots.
The card is reported as 8265 / 8275.

Some notes:

1. In the iwm manual it says: "This driver requires the firmware built with the iwmfw module to work." I'm total newbie for Dfly - do I need to do something special here? Only thing I did was adding if_iwm_fw="YES" into boot/loader.conf, otherwise there was no driver attached to the device.

2. I'm thinking - maybe the card is actually 8275 and the driver supports only 8265 at the moment?

Thanks.

Same with 5.2.2_REL live image on ThinkPad L380.
