  1. The above workaround does not work every time, once or twice and then you need to reboot. I got some debug logs from the driver, dmesg is flooded with this error : [85658.544429] brcmfmac: CONSOLE: 085641.821 wl0: PHYTX error [85660.512477] brcmfmac: CONSOLE: 085643.786 wl0: PHYTX error [85660.512502] brcmfmac: CONSOLE: 085643.788 wl0: PHYTX error [85662.404206] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 [85664.964270] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 [85664.964292] ieee80211 phy0:
  2. So, I did test with multiple firmware revision : 7.45.96.0, 7.45.96.40-apsta, 7.45.96.53, 7.45.96.61, 7.45.96.68, 7.84.17.1 They all have the same behavior, except 7.45.96.0 and 7.45.96.40-apsta which crashes after only 1 day (instead of ~4 for the others); and 7.84.17.1 which create a very high CPU usage and is not usable. I found a workaround to reset the Wifi chip without rebooting : echo -n "fe310000.mmc" > /sys/bus/platform/drivers/dwmmc_rockchip/unbind sleep 1 echo -n "fe310000.mmc" > /sys/bus/platform/drivers/dwmmc_rockchip/bind It's working but not
  3. Hi @denni_isl, Did you find a solution to this problem ? I believe this is coming from the Wifi driver brcmfmac. I noticed the same behavior on my RockPi 4 B when using a weird firmware from Broadcom instead of Cypress (brcmfmac43456-sdio.bin version 7.84.17.1). # strings /lib/firmware/brcm/brcmfmac43456-sdio.bin | tail -n 1 43455c5-roml/43455_sdio-pno-aoe-pktfilter-pktctx-lpc-pwropt-43455_ftrs-mfp-noclminc-clm_min Version: 7.84.17.1 (r871554) CRC: 72494685 Date: Thu 2020-05-14 17:41:11 KST Ucode Ver: 1043.20424 FWID: 01-3d9e1d87 Once reverted to
  4. The issue is still here with the firmware v 7.45.96.68. Wifi crashed a little bit before reaching 5 days uptime. I will see if there is a way to reset the wifi chip, as a workaround. Unloading and reloading the module is not enough. @Werner Which firmware are you using with you Pinebook ? ( You can check it with `dmesg | grep brcmfmac`)
  5. Hi, Thanks for your answer. No, who would that be ? The manufacturer or the kernel developer ? According to some rasberrypi forum, this type of errors could come from the firmware. I found a newer one (v 7.45.96.68) here : https://github.com/armbian/firmware/pull/19 I'll give it a try and keep you updated.
  6. Hi, I'm using a RockPi 4 B as a wifi access point. Everything is working fine with good performances until the Wifi stop working, usually after 3-4 days. When that happens, dmesg is flooded with these logs : [221057.075187] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 [221057.075202] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110 [221124.657840] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 [221127.217786] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_
