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):
[ 412.947747] brcmfmac 0000:01:00.0: enabling device (0000 -> 0002)
[ 413.059831] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43752-pcie for chip BCM43752/2
[ 413.096587] brcmfmac 0000:01:00.0: Direct firmware load for brcm/brcmfmac43752-pcie.txcap_blob failed with
error -2
[ 419.211343] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: FW failed to initialize
[ 419.219481] brcmfmac 0000:01:00.0: brcmf_pcie_setup: Dongle setup failed
[ 419.226214] ieee80211 phy0: brcmf_fw_crashed: Firmware has halted or crashed
Not sure what exact firmware I would need to use. From SparkLAN I got the following:

Did anybody ever progress on getting this to work?
Any help would be much appreciated. Thanks!
