Hi Johan,
Please note BDA values listed below are in the firmware (FW) data
order, but the actual BDA value should be in the reverse of that order.

Apologies for the delay. As of now, we have observed the following
values in the upstream firmware files for default BD addresses.
We will confirm ASAP if there are any changes.

Thanks a lot for these. I see now that the default Trogdor address Doug
reported (39:98:00:00:5a:ad) appears to comes from the fw too:
$ od -x crnv32.bin | grep 5aad
0000020 0000 0000 5aad 0000 3998 0008 0008 0000
which means that patch I sent this morning should be all that is needed
for those machines at least.
Yes correct, it will work for Trogdor
Can you please confirm that all the WCN39xx have OTP storage for an
address that an OEM can choose to use?
We are checking with internal FW team, will confirm on it.
If that's not the case then we could simplify things by always marking
their addresses as invalid, but I assume that they all have address
storage.
