MBR Parameters and Bootloader Settings

[superpak]

Hi,

Referring to the figure at the end of this page:

infocenter.nordicsemi.com/index.jsp

I have a question regarding the MBR parameters and the Bootloader Settings in the memory layout. What does MBR Parameters and Bootloader Settings actually contain and where can I find more information about these parameters and settings?

Thanks.

Bootloader Settings: A bootloader settings page contains information about the current DFU process. In addition, it can contain information about the installed application and the firmware version. See this link for more information.

MBR Storage Parameters: This used to store the SD_MBR_COMMAND_COPY_BL or the SD_MBR_COMMAND_VECTOR_TABLE_BASE_SET command when resetting the IC. E.g. under a bootloader update. Also if reset or power is lost, the MBR will read the stored commands and continue the update process. Upon reset the MBR read the stored commands, which will not be erased before the update is finished. Seeing that there is a “copy bootloader” command, the MBR will check if the bootloader was successfully copied, if not, it will re-write the bootloader to the bootloader section.

The links to documents are not working. Can you please repost the same?
