I have both a 43341 and 43362 Wi-Fi SDIO module up and running on this platform already using the standard bcmdhd. I am told by some Broadcom folks that the brcmfmac driver should support concurrent connections which is something the bcmdhd does not do and that is my primary motivation for getting the fmac driver up and running. The brcmfmac driver is included in NXP's kernel git and I have successfully built it and have it on the Ultralite platform running kernel 3.14.38. When I attempt to insert the module using the command insmod brcmfmac.ko firmware_path=ISM4334X_Wifi_FW_6.10.190.49_P.bin nvram_path=ISM4334X_NVRAM_C1.txt I receive the following errors: brcmfmac: Unknown symbol brcmu_pktq_mlen (err 0) brcmfmac: Unknown symbol brcmu_pkt_buf_free_skb (err 0) brcmfmac: Unknown symbol brcmu_pktq_init (err 0) brcmfmac: Unknown symbol brcmu_pktq_penq_head (err 0) brcmfmac: Unknown symbol brcmu_pktq_pdeq (err 0) brcmfmac: Unknown symbol brcmu_pktq_peek_tail (err 0) brcmfmac: Unknown symbol brcmu_pktq_flush (err 0) brcmfmac: Unknown symbol brcmu_pktq_pdeq_match (err 0) brcmfmac: Unknown symbol brcmu_pktq_mdeq (err 0) brcmfmac: Unknown symbol brcmu_pktq_penq (err 0) brcmfmac: Unknown symbol brcmu_pktq_pdeq_tail (err 0) brcmfmac: Unknown symbol brcmu_pkt_buf_get_skb (err 0) brcmfmac: Unknown symbol brcmu_d11_attach (err 0) insmod: ERROR: could not insert module brcmfmac.ko: Unknown symbol in module I'm not sure that the firmware_path and nvram_path should be specified in this manner, but I doubt that is what is causing these errors. The module compiled and built just fine so I am assuming that there are some dependencies that aren't being met. Is there another module that I need to load before attempting to load the fmac driver?
