I see the following output on the firmware console:

otp main...
Table initialized..
streamCnt 0
Golden Bin/fake Board Template used ...
otp done...
assertion failed? pc=0x948f19, line=5555, dump area=0x40ad04
Target ID: 0x4100016c (1090519404)
Debug Info:
0x4100016c 0x000015b3 0x00948f19 0x00955b31
0x00948f19 0x00060530 0x00000004 0x00000000
0x00000000 0x004045f0 0x00404610 0x00955a00
0x0000

However, the AP where OTP now fails is an engineering sample,
and probably doesn't contain any valid calibration. It did work
in the past, but with the latest ath10k the driver doesn't load
because of OTP failing. So maybe that output is helpful here.
