Hi guys
I stumbled over this thread from a little over a year ago [1].
I lately tried my take at this, however, initially even on latest linux-next it did not even recognise my card.
0000:01:00.0 Network controller: Broadcom Inc. and subsidiaries Device 449d (rev 02)
Once I added that PCI device ID to drivers/net/wireless/broadcom/brcm80211/brcmfmac/pcie.c the driver at least
picked it up:
[ 27.712436] brcmfmac 0000:01:00.0: enabling device (0000 -> 0002)
[ 27.826371] brcmfmac 0000:01:00.0: brcmf_pcie_probe: failed to parse OTP
[ 27.833126] brcmfmac: brcmf_pcie_probe: failed 14e4:449d
[ 27.838498] brcmfmac: probe of 0000:01:00.0 failed with error -22
Looks like it needs more information but I am unsure to what exactly to add where. Last I got the following
(git diff at the very end):

Not sure what exact firmware I would need to use. From SparkLAN I got the following:

I did get RK3588 EVB and the customer board using the same module to
work well using the OOT driver supplied with the 5.10-basis BSP.
Unfortunately I no longer have access to the patches so this is from memory.
It needed various incremental mods including an upgrade of its use of
the firmware API to the modern one so it could initialize the module at all.
After it could come alive but fail in operation, the final problem with
it I traced where it choked in the driver, it turned out to happen quite
early and simply... something that was expected to have been set by the
80211 stack else it would bail - it had its own comment explaining that
this was why it would get into trouble otherwise on 5.10 - was simply no
longer set with later 80211 from mainline and always bailed there.
Removing the check got it working well.
Making the mainline driver support it would have been much better, but
since the firmware is newer than the existing driver, without
@broadcom.com help that's a hiding to nothing. Patching the OOT driver,
it's out of scope to send it here when I did have access to it.
> Any help would be much appreciated. Thanks!
Sorry that's not as useful as it could be, but the OOT path can be made
to work is the news.

I assume you use the .bin and .blob already. Which n ram you need I don't
know. Does the ReadMe have any clues on that?
Cypress/Infineon added 43752 SDIO support so I am not sure if your patch is
correct in marking it as WCC chip. Can you run strings command on firmware
file, ie.:
# strings fw.bin | tail -5
Also let's try to enable some debug levels. Can you enable CONFIG_BRCMDBG
and rebuild the driver?
Then load the driver module with debug parameter set to 0x1c1416.

Arend

I refreshed my memory reading the email conversation you referred to. What

Maybe you can hack it to be unconditional and see where it gets you.

The remaining issue was related to scanning:
5.083312] brcmfmac: brcmf_escan_prep ### List of SSIDs to scan ### 1
[ 5.083313] brcmfmac: brcmf_escan_prep 0: Broadcast scan
[ 5.083314] brcmfmac: brcmf_fil_iovar_data_set ifidx=0, name=escan,
len=180
[ 5.083722] brcmfmac: brcmf_fil_cmd_data Firmware error: BCME_VERSION
(-37)
However, I think the driver has that covered now.
