How to perform a factory reset of nrf52840?

[Rajat]

Hi everyone,

This might seem like a silly post, but this happened.

I build and ran the example QSPI code given in the sdk. 

But after that if i try to run my own code of freertos along with BLE. It just doesn't run and it freezes.

I think i erased some important part of the memory, Can anyone suggest me how to proceed for this kind of problem?

If i press the reset button on the nrfPDK ,it runs the previous code that was uploaded and not the current one.

This is very weird problem i had ever faced.

I  didn't make any changes to the sdk example, I ran that code as it is.

Thanks

Rajat.

Hi Martin,

This did solve my problem.

But ,now the question arises HOW TO USE BLE AND EXTERNAL FLASH MEMORY TOGETHER IN ONE SINGLE CODE?

I am trying to write some data to external flash memory that uses QSPI. But as soon i run the code of QSPI. MY program stops and nothing works untill i load it with the softdevice 140 hex file using nrfGoSTudio.

What is the reason for this ?

What can be the solution to this?

Thanks 

Rajat!
