Bwfm problems

Hello,

So I have a raspberry pi 4b which I want to use as a WAP (Wireless
Access Point) using its onboard wifi chip, which does support HostAP as
I have seen guides on it before which specifically state it has the
capability.

However for whatever reason I get errors saying that the chip does not
support HostAP and or the driver (bwfm) does not support AP. However
checking the manual pages from openbsd which can be found here:
https://man.openbsd.org/bwfm

It clearly states that the driver supports HostAP, thus if the chip I am
using is being detected, (and works fine when connecting to AP's), it
should support HostAP too.

I investigated more into the issue and found the following within my
syslogs:

Jan 22 14:07:09 PolarRouter /bsd: bwfm_sdio_buf_read: error 60
Jan 22 14:07:12 PolarRouter /bsd: bwfm_sdio_buf_read: error 60
Jan 22 14:07:12 PolarRouter /bsd: bwfm0: failed loadfirmware of file
brcmfmac43455-sdio.openbsd,acpi.txt
Jan 22 14:07:12 PolarRouter /bsd: bwfm0: could not init bus
Jan 22 14:07:16 PolarRouter resolvd[72728]: writev: Invalid argument
Jan 22 14:07:16 PolarRouter /bsd: bwfm_sdio_buf_read: error 60

It seems the driver is not properly functioning, as it can not be
loaded, does anyone know how to fix this, according to fw_update, all
the firmware needed is installed for the system, so I am not sure what
else I am meant to do :/

Any advice would be good, I would like to get this working :)

Thanks,
