- Connectors: SODIMM 204 pins
Resources
Workaround
- When you get that kind of error at Wi-Fi initialisation:
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
- You can try to unload/reload the driver:
# modprobe -r brcmfmac # modprobe brcmfmac [ 1881.792273] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Aug 29 2016 20:48:16 version 7.45.41.26 (r640327) FWID 01-4527cfab [ 1881.850588] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
