[Kernel-packages] [Bug 2013027] Re: Issues over broadcom brcmfmac43455 firmware
I have diagnosed the problem as follows.
My broadcom 43455 adapter needs:
1. a different brcm43455-sdio.txt file from the one supplied in ubuntu,
which is a cypress provided version.
2. a different brcm43455-sdio.bin file from the one supplied in ubuntu,
that again is a cypress provided version
3. a different brcm43455-sdio.clm_blob file from the one supplied in
ubuntu
Now, 1 and 2 are no issue: I can supply the files needed by my hardware and put
them side to side to the ubuntu supplied ones. This is because the system will
seek `brcm43455-sdio.AZW-Z83 II.{txt, bin} first.
Incidentally, the txt file can be easily taken from the nvram of my system,
while the bin file is the one that is supplied in armbian, libreelec etc, that
for some reason is not the same as the cypress one found in ubuntu.
The real problem is 3. And this is because without the file made for my
hardware, the wifi will work in the 2.4 GHz band, but not in the 5GHz
band. However the file name for this does not appear to be adapted to my
system. Namely, if I put a 'brcm43455-sdio.AZW-Z83 II.clm_blob' file
side to side to 'brcm43455-sdio.clm_blob' that will be ignored.
This makes it impossible to place board specific brcm files *side to
side* the those currently specified by the distro (unless I miss
something). If this is the case, then there are two possible
workarounds:
1. Make a deb file with a diversion for the clm_blob file
2. Use the brcmfmac module option `alternative_fw_path` to specify and
alternative firmware path for my brcm hardware and put my bin, txt and clm_blob
files there
However, I really tend to think that these are just ugly workarounds for
what is ultimately an issue with the brcmfmac kernel module. If the
module can determine that for by board the filename should be
`brcm43455-sdio.AZW-Z83 II.{txt,bin}` for the txt and bin pieces of the
firmware, then why cannot it look at `brcm43455-sdio.AZW-Z83
II.clm_blob` before falling back to `brcm43455-sdio.clm_blob`? That
would make it easy to put different firmwares in the the brcm firmware
directory side by side and make the framework that is already there for
the txt and bin files actually useful.
Please consider reopening the issue, passing it to the brcmfmac
maintainers.

>apport-collect 2013027' and attach dmesg from both when using the original ubuntu and the windows firmware. I'll add dmesg after re-install of of the original linux-firmware from ubuntu which should be close to what original ubuntu does but might not be totally equivalent to it in case some non-ubuntu file is not overwritten/removed.
