Enabling power to QSPI flash before programming

[kpreiss]

We would like to program an external QSPI flash device connected to the nrf5340 micro.  The power to the QSPI flash is enabled via one of the micro pins.  Is there a way to set the nrf5340 micro pin to a known state prior to programming the external QSPI using nrfjprog?  The qspiloader.py python script is too slow...

Thanks

Hi, 

Is it possible to share the qspiloader.py?

It might help to increase the SWCLK freq. It looks to be set to 2KHz by default: https://github.com/NordicSemiconductor/pynrfjprog/blob/master/pynrfjprog/LowLevel.py#L46
