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 leastpicked 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 -22Looks like it needs more information but I am unsure to what exactly to add where.

Any help would be much appreciated.
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 -5Also 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. Regards, Arend Thanks!
