I get the following messages in the kernel log: brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive strength init done for chip 4324 rev 6 pmurev 17 brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50 [repeated] and the network interface is never created. I'm running kernel 3.18.4, my brcmfmac43241b4-sdio.bin is identical to the one in the linux-firmware repository, and I have attached the brcmfmac43241b4-sdio.txt that I have extracted from the EFI variables. Any help would be appreciated.
