Use mbr instead bootloader

[Vladimir]

Hi. I have several questions about mbr.

1). Will mbr finish to write after unexpected power off?

2). Can I copy softdevice + application or only application using sd_mbr_command_copy_sd?

I can't use bootloader with communication interface because of some reasons. Application now can download the new firmware into buffer section. Will I need to use booloader just to copy from buffer (app + sd or app) or I can use only MBR?

I can't answer the first question, but I have successfully used nrf_dfu_mbr_copy_sd() to update the softdevice and my application at the same time. To do this I generated a .bin file with the appropriate amount of padding between the softdevice and my app and wrote that to a scratch section of flash.
