The builtin wifi on RPi0 is working fine with OpenWrt 18.06.2, but there are strange messages in dmesg:
[ 7.871774] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1 [ 7.908434] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.raspberrypi,model-zero-w.txt failed with error -2 [ 7.925187] brcmfmac mmc1:0001:1: Falling back to user helper [ 8.337606] firmware brcm!brcmfmac43430-sdio.raspberrypi,model-zero-w.txt: firmware_loading_store: map pages failed [ 8.444305] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1 [ 8.458322] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.clm_blob failed with error -2 [ 8.473864] brcmfmac mmc1:0001:1: Falling back to user helper [ 8.497345] firmware brcm!brcmfmac43430-sdio.clm_blob: firmware_loading_store: map pages failed [ 8.511562] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-11), device may have limited channels available [ 8.533376] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Aug 29 2016 20:48:16 version 22.214.171.124 (r640327) FWID 01-4527cfab [ 8.586314] usbcore: registered new interface driver brcmfmac
What could be the problem here?
And another question:
The official RPi0 firmware contains the file
bcm2708-rpi-**zero**-w.dtb, while the OpenWrt /boot/ folder has
bcm2708-rpi-**0**-w.dtb. What's the difference? The official version seems to be newer, should I use that one?
Thank you in advance.
