mwifiex firmware mrvl/sd8987_uapsta.bin missing in the firmware git

mwifiex firmware mrvl/sd8987_uapsta.bin missing in the firmware git

[Andreas Kemnade]

Hi,

I am a bit wondering, but there is mrvl/sd8987_uapsta.bin
referenced in the driver, but apperently it is not in the firmware git.

https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_8987/sdiouart8987_combo_v0.bin

seems to apparently work. How to proceed? Should the file be renamed and added
to the fw git?
The uartuart8987_bt.bin needed by the btnxpuart driver is there.

It is just nasty to have a driver for a device but some manual matching of firmware

BTW: there is also https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_8987/sd8987_wlan.bin

Regards,
Andreas

Hi Andreas,

Excellent point. Please note, that btmrvl_sdio needs an SDIO BT FW. So, mrvl/sd8987_uapsta.bin should preferably be a such a combo FW.

Unfortunately, to my knowledge, none is available publicly. Also, after the acquisition of Marvell IoT, NXP regrettably decided to develop mwifiex downstream, here https://github.com/nxp-imx/mwifiex.

It is what it is. Due to licensing, the FW binary should come from NXP. I cannot arrange that.

Kind regards,
Tamas

as said the firmware here seems to work for me (after renaming):
https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_8987/sdiouart8987_combo_v0.bin

I can use bluetooth together with btnxpuart driver and firmware
/lib/firmware/nxp/uartuart8987_bt.bin which is officially part of
linux-firmware and also in the same directory in the imx-firmware git
mentioned above.

Regarding license I found that snippet in nxp/SCR_nxp.txt:
Package:                   FwImage_8997, FwImage_8987, FwImage_8801,
FwImage_9098, FwImage_IW416, FwImage_IW612 Outgoing License:
LA_OPT_NXP_Software_License - Production Use, Section 2.3 applies
License File:              EULA.txt

Section 2.3 is:
2.3.        Additional Distribution License

But that is all legalese and I am not a lawyer... Best is of course
something officially added from NXP. No idea if it can be done
otherwise. How to make NXP add something?

Andreas

Would it be possible for you to get these firmware files added to the
official linux-firmware git repo? 

I am not using sd8987 myself, from what I read in the thread probably
some file name would need to be corrected (I would say in the mwifiex
driver).

Thanks,
Francesco

I'd appreciate if NXP could additionally greenlight addition of:

https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_IW416_SD/sdiouartiw416_combo_v0.bin
https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_IW416_SD/uartiw416_bt_v0.bin

...to the linux-firmware repo.  They're necessary for SD8978 (aka IW416),
which has been supported by mwifiex since commit bba047f15851 ("wifi:
mwifiex: Support SD8978 chipset").

Back in the day when I submitted that commit, I concurrently reached out
to NXP.  Sherry Sun kindly responded that Dinesh Phatak and Pankaj
Razdan need to confirm upstreaming into linux-firmware (both +cc).


The problem is that mwifiex firmware originating from

https://github.com/NXP/mwifiex-firmware/

is available under a simple 3-clause licence, but only contains outdated
firmware for older chips.


More recent firmware available from

https://github.com/nxp-imx/imx-firmware

seems to be distributed under different and much longer licensing terms:

https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/LICENSE.txt

So I think we need confirmation from NXP before we can add the firmware
to the linux-firmware repo.

Thanks,

Lukas

I am not responsible for firmware release.

You can get updated firmware from https://github.com/nxp-imx/imx-firmware/.

Normally the firmware will be merged to NXP Yocto project.

Yes, I am aware of both, and most of the people in this thread is aware of the second.

I was wondering if you could facilitate within NXP having these firmware files
added to the linux firmware git repository, where they should be for various
reasons. To whom should I write such a request? Can you help in any way?

yes, I think most of us are aware of this.
So what is the problem: E.g. I have bought a new device, ported a linux distro
to it, ok, for my personal use, I can just download the firmware from
mentioned link. So now I want to pave the road for others so that wifi
"just works" So the question is about redistributing the firmware:

Citing License:
"(b)     to copy and distribute as needed, solely in connection with an
Authorized System and for use in combination with a NXP Product,
non-confidential NXP information provided as part of the Licensed Software for
the purpose of maintaining and supporting Authorized Systems with which the
Licensed Software is integrated."

to me it looks like the firmware might not allowed to be part of a linux
distribution if that linux distribution is not just for one device.
So an official permission to do so is really helpful. The most clearest
thing would be an addition of the files to the official linux firmware
repo (git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git)
by some NXP people.

Andreas

Hi Francesco,

I am not responsible for mwifiex or wifi firmware aspects, but I have forwarded this query internally within NXP and added few stakeholders in CC who can comment in this regards.
