 |
|
I'm trying to replace firmware for intel 7260 WiFI card, from iwlwifi-7260-7.ucode to the latest iwlwifi-7260-8.ucode
Both iwlwifi-7260-8.ucode and LICENSE.iwlwifi-7260-ucode are placed in /lib/firmware
| Code: |
-rw-r--r-- 1 root root 679780 мар 25 18:40 /lib/firmware/iwlwifi-7260-8.ucode
-rw-r--r-- 1 root root 2041 мар 29 02:08 /lib/firmware/LICENSE.iwlwifi-7260-ucode
|
I rebuit kernel and modules
| Code: |
make clean
make && make modules_install
rm /boot/kernel-3.13.6-gentoo
cp arch/x86_64/boot/bzImage /boot/kernel-3.13.6-gentoo
|
and rebooted
after reboot modinfo iwlwifi shows old version - iwlwifi-7260-7.ucode
| Code: |
filename: /lib/modules/3.13.6-gentoo/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko
license: GPL
author: Copyright(c) 2003-2013 Intel Corporation <ilw@linux.intel.com>
version: in-tree:
description: Intel(R) Wireless WiFi driver for Linux
firmware: iwlwifi-3160-7.ucode
firmware: iwlwifi-7260-7.ucode
srcversion: A161C8D26F94219F5CD7026
|
but dmesg shows that the correct firmware was loaded (22.24.8.0 - correct version)
| Code: |
[ 7.374790] iwlwifi 0000:04:00.0: loaded firmware version 22.24.8.0 op_mode iwlmvm
|
So the questions are: which one of these two tools show correct info? How can I be sure that the correct version of firmware loaded, and where from 'iwlwifi-7260-7.ucode' was taken as such file does not exist on HDD anymore? |

Both might just be ok :
- build module X v7
- install module X v7
- if make clean doesn't remove module X from /lib/modules... but like i suppose only handle the module files from /usr/src/linux
- now build X v8 as build-in kernel
- blahbalbh install kernel, reboot...
module X v7 is no more in use as your kernel use its build-in kernel v8.
kernel boot : dmesg show X v8 loaded
/lib/modules/3.13.6-gentoo/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko still exist, but is not use.
modinfo the module X and you get v7 answer. |
