carl9170fw: custom build incompatibility issue

carl9170fw: custom build incompatibility issue

[Chris Pechard]

I tried to build an unmodified carl9170fw firmware based on 1.9.0  
tag.Unfortunately when dropping it in my /lib/firmware directory, I get  
unsupported firmware when connecting my usb wifi device. If I used the  
precompiled version based on the same tag, everything is working fine.  Below is 

the config I used to build the firmware. Any help to get this  working would be 
appreciated.

Best regards,
Chris

np, just attach carl9170's .config and the "broken" firmware file.

The only thing wrong is the lack of fw metadata (which is kind of
obvious since the the firmware is somewhat customizable).


You have two options:

 - either concat carl9170.fw and carl9170.dsc into carl9170-1.fw
   (by hand).

 - autogen.sh install [also adds miniboot + fw checksum]
   (since CONFIG_CARL9170FW_MAKE_RELEASE is y,
	and CONFIG_CARL9170FW_RELEASE_VERSION=1)

Best Regards,
	Christian

Thanks Christian for the quick turnaround, option 2 did it.
