I too am working with a WL1271 module and have just today got it
connected to an Atmel ARM9 development kit (AT91SAM9G45-EKES). So far it
appears to work but I have been gated by the firmware and NVS file issues.

I have a firmware binary, but it seems to be a newer version
(6.1.3.01.5) than what you are using. Does anyone have any idea if this
version will work? It seems to be the only one available on TI's
website. Additionally, our device manufacturer has been hesitant to
provide any support because we are on an unsupported platform and opted
to use the open source driver. Are there any other ways to obtain an
older version of the firmware?

The NVS file is another problem. TI's website has instructions to use a
cryptic tool that appears to come with their driver package. There is no
source for this tool and for obvious reasons would not work for us.

Anyway, I'd like to help in anyway I can. I've taken a look at the
twilan.ini file and I see the commonality with wl1271_ini.h. It would be
relatively easy to write a tool that parses the INI file and generates
the common part of the NVS file. However, I'd have no idea how to
generate the device specific calibration or the few fields missing from
the INI file.

Thanks,

Logan
