Hi,
I have a custom prototype board based on nRF52833 which runs a working firmware and I have not any other prototype ready to hand.
Unfortunately, I think that the source code is screwed up and doesn't include all the feature available from the board (maybe it's an older version or someone screwed it up) so I cannot compile and upload it because I would lost the 'reference' firmware which is now on the board.
In other words, I need to download and save the current firmware on the board in order to be able to upload it again until the code I am fixing doesn't work as before.
I took a look at nrfutil but it doesn't provide any option to download the firmware from the board.
Is there any way to download and save the current .hex file from the board and re-upload it later?
Thank you in advance.
PS: I am using the nRF52DK to upload the firmware and Segger Embedded Studio.
