Hi David and Sean, I am considering using the Murata WiFi module LBWA1KL1FX which is based on the CYW43364 / Broadcom BCM43364 Chipset. Our design criteria is that it must be supported by mainline Linux. Searching kernel log file to find that you added bcm43364 wireless chipset to broadcom/brcm80211/brcmfmac driver, could you please advise how stable and reliable to run brcm80211/brcmfmac for CYW43364 / Broadcom BCM43364 Chipset? In addition to add CONFIG_BRCMFMAC and CONFIG_BRCMFMAC_SDIO, should I also add CONFIG_BRCMFMAC_PROTO_MSGBUF, CONFIG_DMI, CONFIG_BRCMFMAC_PROTO_BCDC and CONFIG_OF? Thank you very much. Kind regards, Jupiter
