Hi Mohsin,
I do not have the MQX example you need.
But if you are able to erase/write the Flash memory in your MQX application you may change the FNET Bootloader parameters from your application.
They are placed at the beginning of the last logical-block of the on-chip flash memory (e.g. 2KB for Kinetis, 4KB for Kirin3).
The Bootloader parameters organization is defined by the fapp_params_flash structure placed in the
fnet\fnet_demos\common\fnet_application\fapp_params.h
Thanks,
Andrey Butok
