It seems the debug logging needs a few additional config options
additionally.

Right. I wasn't sure you were aware ;-)
Thanks,

Hello, I'm facing the same problem on sdio version of AP6275 module in mainline kernel. But I found a very old version from here could work with mainline brcmfmac driver.
Link: https://bbs.t-firefly.com/forum.php?mod=viewthread&tid=3107
Besides who I should ask to make proper firmware for it into linux-firmware repo?

Thanks for the info.
The firmware on the firefly thread doesn't seem to have a CLM blob that
the mainline driver wants, just two types of the ~900KB main firmware
for AP mode support or not.
It also doesn't have _sdio or _pcie in the filenames... I tried it but
although it's different in what it read after downloading NVRAM
[ 3.775602] brcmfmac: brcmf_pcie_download_fw_nvram: sharedram_addr
0xfa2c05d3
(the rockchip SDK firmware says 0xfa1a05e5)
it still times it out a few seconds later as unresponsive after the fw
load... maybe it is for SDIO only, or the lack of CLM, present in the
Rockchip fw, means it won't get anywhere.
> Besides who I should ask to make proper firmware for it into linux-firmware repo?
It would also be great to hear if the PCIe firmware from Rockchip aimed
at the OOT driver was definitively incompatible with the mainline driver
and we have to find a solution for that from Broadcom, or it is expected
to basically work. I realize it might not be easy to get an answer
internally but this chipset is likely to appear in more RK3588 SBCs soon
since it's the one on the evb.

Actually you can use any other clm info blob with this firmware as I tried. I also uploaded this to armbian's firmware repo. Hope we could get the proper firmware uploaded by Broadcom soon.

Thank, I tried this, it did accept to download the clm part from the
Rockchip SDK firmware.

I have the AP6275 module EN signal with the gpio wired to it as an
"always-on" gpio regulator in DT, and don't use the hacky rfkill thing
the rockchip SDK came with.
It's on top of 6.1.0-rc4.
Does your setup differ from this?

Almost same, except I'm using sdio driver (radxa rock 3a+their a6 module (AP6275S)). And I'm using mainline 5.19.8(self-compiled armbian edge) while I was testing.

A separate CLM blob may not be necessary when it is built-in in firmware
which can be overloaded by separate blob, but in that case it is optional.

That sharedram_addr looks wrong. Probably the firmware is not booting for
some reason. Can you provide a URL where I can download the rockchip
firmware? My internet search skills are lacking.

Right now I don't have enough information to comment on this.

That error report happens when using sdio version firmware for pcie
card. If you want a new version of rockchip firmware, check this:
https://gitlab.com/rk3588_linux/linux/external/rkwifibt/-/tree/linux-5.10/firmware/broadcom
Currently seems only firmware from firefly bbs above works with SDIO
version and mainline now. And no known version PCIE firmware can work
with mainline driver.

I honestly don't know what entity provides the ampak wifi module. I guess
it is coming from Synaptics, but I am not sure. I rather fix the mainline
driver to make it work with the firmware (if possible) instead of releasing
a specific firmware for mainline.

That'd be great... I have some amount of time to help with this if
something useful I can do for pcie case.

The AP6275 PCIE ones there are the firmware files from the rockchip Sept
SDK drop that I started with... they give the behaviour that the
sharedram address probed from the device is
[ 3.744635] brcmfmac: brcmf_pcie_download_fw_nvram: sharedram_addr
0xfa1a05e5
and shortly after sending the nvram data
[ 9.876580] brcmfmac 0002:21:00.0: brcmf_pcie_download_fw_nvram: FW
failed to initialize: 0xfa1a05e5

Thanks for that. The firmware indeed seems to originate from Synaptics
and this module can be found on wifi-alliance product finder:
https://www.wi-fi.org/product-finder-results?sort_by=certified&sort_order=desc&keywords=ap6275
We have no known contacts there and they do not seem to have much
interest in open-source. In that gitlab repo I see they are providing
bcmdhd driver and I assume they consider that sufficient.
Will see what I can do. First have to think on how to approach this
failure to get most out of a debug effort. I do not have the module over
here so we would need to go back and forth. The fact that the issue is
seen on both SDIO and PCIe is somewhat encouraging.

Yes it seems that at some point with some firmware, SDIO has worked for,
eg, Angus. And, it should work well with bchdhd (but that does not seem
to work for scan for me on v6.1-rc5 uplevel with the firmware load
changed to use kernel apis; but the firmware has no timeout on bcmdhd).
So it doesn't feel a million miles away.
I have the hw, and (paid) time to help with debugging this "pair of
hands" style. I'm also a little familiar with the kernel code and can
try jiggle things autonomously if you can prompt what is interesting.

This is the firmware we have been using for SDIO. It was sent to us
directly by SparkLAN so not sure how it compares to other variants.

Currently it's broken for hotspot mode but I haven't had the chance to
see if that is FW or something further up the stack.

I see. So could you load bcmdhd and provide log. Preferably with higher
debug level. It also has a module parameter for it. I think it is called
dhd_msg_level and please set it to 0x817.

It's here:
https://warmcat.com/ap6275p-dhd-log1.txt
after boot he shows a wlan0
wlan0: flags=-28669<UP,BROADCAST,MULTICAST,DYNAMIC> mtu 1500

TX packets 11 bytes 866 (866.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
The dhd OOT driver comes with a rockchip-hacked rfkill driver which has
all sorts of things in it related to wakelocks I removed, I built that
too and rfkill reports
# rfkill
ID TYPE DEVICE SOFT HARD
0 wlan phy0 blocked unblocked
1 wlan brcmfmac-wifi blocked unblocked
"brcmfmac-wifi" is a literal in the dhd driver sources, confusingly.
Mainline brcmfmac is not built or inserted as a module for this test.
# rfkill unblock
shows everything unblocked, but connmanctl can start scans but never get
any results. But it's happy with the firmware after hacking it to use
updated apis.

Hi Andy,
Thanks for the log. Together with the dhd driver sources I could make
some sense of it. Perhaps you can try the following hack and see if we
make it over the first hurdle.

Thanks, I tried it, but although it looks necessary, there's evidently
something else since the result was the same.

Ok. Something is off there. Maybe I tried to be to smart. How does that

It's inline with the other logs, it seems to be coming before the actual

Good job! I was testing you obviously. You passed. Nah, I just feel stupid.

Thanks. Will clean it up and formally submit it. I also had a quick look
at the SDIO variant, but not seeing anything obvious there in terms of
firmware loading.

Arend
Great work! If you need to test SDIO variant, I could help with it.

No it's great, the point is it directly identified the root cause
without access to the platform, it's not so easy.

I only have the pcie module not the SDIO one.
For the scan situation, he understands what is being asked via
connmanctl "enable wifi", but he feels something wrong

52 is EBADE, I recall you mentioned that the scan api had been changed
recently... is this possibly related to that? Grepping around for EBADE
near the function it mentions, it tries to take evasive action if it
sees one in some places already.
-Andy
Seems SDIO variant load firmware correctly without any modification, but also reports this -52 error while scanning.

Thanks for letting me know. So we can focus on scanning. I will reply to
Andy about that.

EBADE is a generic error message indicating something went wrong
communicating with firmware. Not very informative. Were you using any
debug level? Anyway, please load the driver with module parameter
debug=0x5416 and try scanning using iw utility.

My kernel crashed on boot while I was trying things earlier
necessitating a rootfs reflash, I lost the /etc/modprobe.d entry for the
debug.

The root cause is easy. Basically the brcmfmac driver is not on par with
the firmware. brcmfmac uses escan api version 1 and firmware expects
version 2. Fixing it is going to be more difficult. Things start to
diverge on firmware API level. I already had a patch on the shelf
supporting version 2, but it does not match the API your firmware expects.
I was working on supporting multiple vendors, but I need some rework.
The scanning issue confirms the need for per-vendor support. Hopefully I
can spend some time on it.

Arend

If it makes sense for you, I'm willing take a look at your alpha patch
with the idea to align with what the OOT driver does for scan, but I'm
not sure how intricate wading in there is going to get.
I'd need at least some guidance about how to detect which api stack it
wants dynamically if there's more than one "version 2" and likely some
hand-holding about firmware or soc-specific things in places.

... there's the additional quirk that my rebase on mainline of the OOT
driver starts up like mainline now, but doesn't return any scan results
as it is.
So aligning to that may only take us so far without some possibly
non-open knowledge about what the firmware really wants from its
perspective directly without referencing dhd.

Hi Angus,
When you added support for this device in brcmfmac you marked it as a
Cypress device. Are you sure about that? AFAICT this device is coming
from Synaptics.

Hi Arend,
I assumed Cypress based on the fact that it most closely resembled the
4373 from the driver side.
How would I figure out whether it's Cypress or Synaptics ?
When I search the web for it I only find SparkLAN or "AMPAK technology"
references.

Right. Both are based on the same chip architecture that they brought from
Broadcom so the similarities are not surprising.

Earlier my colleague Franky found this link to WFA certificate:
https://api.cert.wi-fi.org/api/certificate/download/public?variantId=103641
WFA and FCC are usually good sources of info. Also the product pages of the
vendors are worth checking. I have them bookmarked out of professional
interest ;-)

I did find FCC references but those seemed ambiguous as well. Thanks for

Should I send a patch renaming SDIO_DEVICE_ID_BROADCOM_CYPRESS_43752 ->
