Hi there,
I am working a WIFI module as follows,

To activate it, need to download 4 image file like Serial Flash Discoverable Parameter coverage.
At the same time I am using a USB to Serial COM port works in 5volt.
But, wifi module accepts 3.3v, so I am using TX, RX from USB Serial COM which has 3.3 level also.
To maintain 3.3 v for WIFI, an external power supply has used.
Not sure, after downloading why factory reset command appears ?
For voltage swing ?
In Serial terminal error massage says,
SETUP: ERROR(ret=9)
All services have been stopped.
Please reboot or setup again.
[PRADA:NVRAM] reboot
