Software update for 52840

[Paul Heyman]

I understand that there is a procedure to update this device via uart or spi. I can't find any documentation regarding this. Is this supported in nRF5 serialization API

Thanks

Paul

You can take a look at the serial secure dfu bootloader example. You will still need to use the JLink on the 52840 to program the bootloader the first time before you use the serial interface to update the device app FW/Softdevice and/or Bootloader. This case might also be useful.
