Hi,

The firmware files for EM9191 are Linux only. Are there any plans to provide Windows executables (similar to EM74xxx and EM7565 ) to allow firmware upgrade on Windows hosts?

Thank you,  
Dmitri K

Hi DmitriK,

You can use the FDT tool to upgrade the .cwe and .nvu firmware files on Windows while waiting for the Windows executable .exe file to be posted.  
You can get FDT tool here [FDT tool](https://source.sierrawireless.com/resources/airprime/software/fdt/#sthash.3wpVzcMv.dpbs)
