Post by Patrick WelchePost by Patrick WelcheDiro's note in
http://mail-index.netbsd.org/tech-net/2012/12/08/msg003778.html
reminded me that I never applied the patch in
http://mail-index.netbsd.org/tech-kern/2011/08/06/msg011131.html
I am writing this logged in via
iwn0 at pci3 dev 0 function 0: Intel Centrino Advanced-N 6230 (rev. 0x34)
so it does work. The unclean part is that I had to comment out the
bluetooth coexistence code. This week I wrote some bluetooth coexistence
Configuring WiMAX coexistence
sending crystal calibration 121, 121
iwn0: fatal firmware error
Do any of you know whether 121 makes any sense?
The code seems to just copy the values from an eeprom...
One thing I did change is
IWN5000_CMD_WIMAX_COEX
which I think should be 92 rather than 90...
It turns out that the calibration error goes away when I set
IWN5000_CMD_WIMAX_COEX back to 90. This suggests that the WIMAX_COEX
code is broken, as 90 doesn't do much - but that is another problem...
Attached is a patch which allows the 6230 to work, and which has
bluetooth coexistence code.
Cheers,
Patrick
