brcmfmac errors on 3b+

Mon Feb 11, 2019 8:29 pm

Hi,

I noticed some errors with dmesg. I have not noticed any issues though with wifi, every seems to work fine, just not sure what these warnings are about:

Code: Select all

 dmesg|grep brcmfmac
[    4.491339] brcmfmac: F1 signature read @0x18000000=0x15264345
[    4.498510] brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac43455-sdio.bin for chip 0x004345(17221) rev 0x000006
[    4.499165] usbcore: registered new interface driver brcmfmac
[    4.829337] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Feb 27 2018 03:15:32 version 7.45.154 (r684107 CY) FWID 01-4fbe0b04
[    4.829890] brcmfmac: brcmf_c_preinit_dcmds: CLM version = API: 12.2 Data: 9.10.105 Compiler: 1.29.4 ClmImport: 1.36.3 Creation: 2018-03-09 18:56:28
[    6.612740] brcmfmac: power management disabled
Is this anything I need to worry about? If so, how can I fix?
Thanks!

Those are just logging messages, not errors. All seems fine.

Thank you, why would some of those lines be in red? I thought that meant there was an issue.

EDIT to add: Those three lines do show up if I run dmesg -l err

No idea, that down to the people who wrote the driver, not us. All those messages are doing is reporting the varaious firmware version being uploaded to the chip, and some other information that might be of use when diagnosing issues.
