Subject: mwifiex: Firmware name for W8997 sdio wifi chip
Date: Fri, 15 May 2020 15:23:53 +0200 [thread overview]
Message-ID: <20200515132353.vfor7v4buzoddfmb@pali> (raw)
Hello!
There is inconsistency in firmware naming for W8997 SDIO wifi chip.
Firmware for this chip is stored in linux-firmware [1] repository under
filename sdsd8997_combo_v4.bin.
But mainline linux kernel driver mwifiex_sdio.ko [2] expects and loads
firmware for this chip from filename sd8997_uapsta.bin.
So result is that W8997 SDIO wifi chip does not work out of box and
people are complaining where to get "sd8997_uapsta.bin" firmware file as
it does not exist [3]. People suggest to rename it.
Do you have any opinion how to solve this problem?
As Marvell is using sdsd8997_combo_v4.bin name for this firmware I would
suggest to extend mwifiex_sdio.ko Linux driver to load this firmware
also from the file sdsd8997_combo_v4.bin.
Also firmware file sdsd8997_combo_v4.bin in linux-firmware git
repository [1] is in version 16.68.1.p179. But there is already newer
version available (e.g. 16.68.1.p197) . Are you able to update firmware
for W8997 SDIO chip in linux-firmware repository to the lasted version?
