How can I restore the original bootloader of a pca10059?

[henrikbrixandersen]

I have used the pca10059 with an external programmer, overwriting the USB DFU bootloader on the board in the process.

Now, I would like to restore the original bootloader of the pca10059. Where can I obtain the hex file for this?

Hi,

Here is the original bootloader including MBR.

Thank you for the swift reply. It seems I might also have cleared the configuration of the UICR registers, so the DC-DC converter is not up and running...
