Go back –> ath10k
The ath10k firmware images are available from linux-firmware.git which all common Linux distributions should install by default. Latest firmware images can be downloaded from ath10k-firmware.git from which they get eventually pushed to linux-firmware.git.
|Hardware||Firmware major version/branch||Latest firmware revision||Intended use||Kernel version required*||Git commit|
* Note: It is possible to use newer ath10k driver on an older kernel with backports project.
First download the firmware image from the links above. In this example we use firmware-2.bin_10.1.467.2-1 from QCA988X 10.1 directory. Then just copy that file as firmware-2.bin to the ath10k firmware directory:
cp firmware-2.bin_10.1.467.2-1 /lib/firmware/ath10k/QCA988X/hw2.0/firmware-2.bin
Then reload ath10k (or restart the system) and you can check if the new firmware is in use.
Note: In some distributions the firmware location can be different than /lib/firmware.
Because firmware changes between versions we have introduced firmware API concept to ath10k. This makes it possible to support different versions of ath10k.
The first version. Firmware images are in separate files: firmware.bin and otp.bin. There's no FW IE support. Deprecated since March 2014 and removed on March 2016.
Embedding both firmware and otp images into same file firmware-2.bin. Firmware meta data provided through FW IE. Added in commit 1a222435a dated Sep 27 2013, for Linux 3.13. Deprecated, no new firmware releases use this anymore.
Adding support for 10.2 firmware for QCA988X and ATH10K_FW_FEATURE_WMI_10_2 feature for 10.2 WMI mappings. Added in commit 24c88f7807fb7 dated Jul 27 2014. Deprecated, no new firmware releases use this anymore.
Adding support for ATH10K_FW_IE_WMI_OP_VERSION. Added in commit 4a16fbec1cd0a dated December 17th 2014.
Adding support for ATH10K_FW_IE_HTT_OP_VERSION, needed to support 10.2.4.48-2 on QCA988X. Added in commit 53513c302f35e March 25 2015.
Workaround for board id being zero on QCA6174 hw3.0 starting from firmware release WLAN.RM.4.4-00022-QCARMSWPZ-2. Added in commit aad1fd7f7677 April 19 2017, first release v4.12-rc1.
Also for QCA9377 hw1.0 fix IRAM bank compatibility starting from firmware release WLAN.TF.2.1-00014-QCARMSWP-1. Added in commit fc8b92635f79 February 2018, first release v4.17-rc1.
