Hi, i'm currently working on Raspberry Pi Zero W for Mainline. Here is my first patch series [1].
Unfortunately i didn't get brcmfmac (connected via SDIO) probed with this patch series against 4.12.0-rc5-next-20170616+ [ 8.389167] brcmfmac: F1 signature read @0x18000000=0x1541a9a6 [ 8.735111] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: May 27 2016 00:13:38 version 7.45.41.26 (r640327) FWID 01-df77e4a7 [ 8.786016] brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012 [ 11.288798] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 11.292822] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 13.848777] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 13.852974] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 16.408762] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 16.413004] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 18.968769] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 18.972965] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 21.528743] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 21.532924] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 24.088745] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 24.092948] brcmfmac: brcmf_sdio_checkdied: firmware trap in dongle [ 26.648764] brcmfmac: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 [ 26.648789] brcmfmac: brcmf_cfg80211_attach: Failed to get D11 version (-110) [ 26.648831] brcmfmac: brcmf_bus_started: failed: -12 [ 26.648842] brcmfmac: brcmf_sdio_firmware_callback: dongle is not responding I already tried the additional patches from Gerd Hofmann's repo [2], but this didn't improve anything. Any ideas what could be the problem? Thanks Stefan [1] - http://lists.infradead.org/pipermail/linux-rpi-kernel/2017-June/006598.html [2] - https://www.kraxel.org/cgit/linux/log/?h=bcm2837
