Héllo James,
As Pali wrote, if fimrware requires signing NDA, I can propose my own
collaboration to NXP !
I am still okay to help, in anyway, with testing or more...
Please, feel free to contact me.

Hello James!
Thank you for reply, but this is something which we did not want to hear :-(
There is an issue in the latest pcieuart8997_combo_v4.bin firmware file
which NXP sent to linux-firmware repository and it is really needed to
fix this issue. It was sent by NXP, so it is expected that NXP do it.
And because it is binary-only file, people outside of NXP cannot do it.
Would you be able to look at this firmware issue as the last thing?
Or as Gérald wrote, could NXP provide source code of that firmware? So
people outside of NXP could look at it? If firmware requires signing NDA
(either individually or via company), then some professional skilled
kernel developers can do it.

Hi Pali,
NXP doesn't have a plan to support mwifiex driver anymore. How should we handle this kind of retired project in upstream?
Thanks,
James

Hello Prashanth!
Thank you for reply. Did you have a time to check this issue?
Gérald did a great testing which shows that version W16.68.1.p195 and
higher of pcieuart8997_combo_v4.bin firmware does not work.

Héllo All,
I made some few tests on EspressoBin-Ultra from GlobalScaleTechnologies,
because of problem with the WiFi.
I have done some quick tests on all the firmware of PCIEUSB-8997 using
the pcieuart8997_combo_v4.bin on OpenWrt 21.02.x
Here is a summary of the tests :
- W16.68.10.p159 = KO
- W16.68.1.p195 = KO
- V16.68.1.p145 = OK
- 16.68.1.p140 = OK
- 16.68.1.p133 = OK
- 16.68.1.p97 = OK
- 16.68.1.p70 = KO
From this user test result can be seen that last two versions of
pcieusb8997_combo_v4.bin firmware file for 8997 wifi+bt card with
official mainline linux kernel driver mwifiex were not properly tested
internally in NXP and are causing serious issues which make 8997 card
basically unusable.
Sharvari and other NXP developers: Do you have some internal testing of
this pcieusb8997_combo_v4.bin firmware for PCIe+USB variant of 8997
wifi chips? Or are you aware of this issue and do you have in NXP some
workaround for it (e.g. at driver level)? Could you please look at this
serious issue and try to debug firmware and release a new version, as
this is obvious fatal error in firmware itself?
Josh, how you in linux-firmware repository handle such, I must say,
"fatal issues"? Wait for vendor fixes or revert problematic commits? Or
something else?
We can revert if we need to, but I think it's not quite that simple.
Because when users starts upgrading linux-firmware packages in their
downstream distributions then basically wifi cards on this 8997 chips
with official mwifiex driver stops working.
The first broken version was committed in Feb of 2019. That's
approaching 3 years ago. Given that this is binary firmware, I have
no idea what else may or may not be included in the updates in the
meantime.

Josh, as Gérald wrote, current binary in linux-firmware repository is
unusable. And there is no reply from NXP for 3 months.
You are right that nobody knows what is in firmware binary, but working
binary is at least usable than non-working binary.
So I would really suggest to start reverting non-working firmware files
if NXP does not respond in few days.
Gérald, what is your opinion? Do you see other way how to make mainline
linux driver work (again)?

Olders looks to works better.
In quick tests, they allow more than 1 clients at a time !
I am still testing the V16.68.1.p145 and report the results after some
longer use...
Hopes it will help...
