Hi, As my cubietruck went down because of a kernel bug in stretch i tought it was maybe better to upgrade to buster since that's around the corner. However now wifi stopped working:
[ 16.871534] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 16.877576] brcmfmac: brcmf_bus_started: failed: -110 [ 16.928040] brcmfmac: brcmf_attach: dongle is not responding: err=-110 [ 16.972120] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed A powercycle doesn't help in my case. Reports of similar issues mention a firmware problem. This is what's currently installed on it: ii firmware-brcm80211 20190114-1 all Binary firmware for Broadcom/Cypress 802.11 wireless cards ii linux-image-4.19.0-2-armmp-lpae 4.19.16-1 armhf Linux 4.19 for ARMv7 multiplatform compatible SoCs supporting LPAE Kind regards, Axel
