How to optimize time when flashing modem firmware at production stage

[Carla31zv]

Good morning,

I have created a python script which allows me to flash modem firmware at production stage.

I'm using modem firmware mfw_nrf9160_1.3.6.zip

I'm using pynrfjprog python module for flashing operations over swd interface.

Flashing takes around 35 seconds.

I would like to know if there is a way to optimize this time of flashing. 

Thanks in advance,

Carla

Hi,

Flashing takes around 35 seconds.

I would like to know if there is a way to optimize this time of flashing. 

Are you looking into ways to reduce time that is needed for flashing?

How long does the flashing last when you use nrfjprog and nrfutil directly?

It is generally recommended that you do full flash erase before flashing. Have you tried to erase the flash completely before programming?

Best regards,
Dejan
