You can use Developer Studio to download to module. (Device -> flash firmware from external file)
Or you can use SCP command to transfer the file to module file system, and then use fwupdate command to update the firmware.

you can try to set the IP address of Windows in the ECM interface to be 192.168.2.3.
And then try if you can ping the module IP address 192.168.2.2.


#13

hi!

what is ECM interface is it mediatek wifi?


#14

of course not.
ECM interface is from the USB of the module.


#15

hi!
problem i dont have interface on windows to ping 192.168.2.2
i work with mango red
may problem is driver on windows side?


#16

hi!
can i change the kernel via swiflash app?

#17

Do you see any network interface in device manager?
Swiflash is a recovery tool that can be used if the device is not booting anymore, so not for normal download.
