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...

Thank you. This "new" (it's already very old) UI refresh of the nordic devcenter has made it almost impossible to find things like this. I really appreciate your answering this question with an actual link that hasn't expired.

In case anyone wonders where is this file attached coming from, it is in the Nordic SDK:

./nRF5_SDK_17.1.0_ddde560/examples/dfu/open_bootloader/pca10059_usb_debug/hex/open_bootloader_usb_mbr_pca10059_debug.hex
