Hi Duncan,
Yes, the MBR params page is only used during SoftDevice or Bootloader updates and not during normal operation.

Gonna make a new post specifically about this, but just to clarify, is the MBR params page only used for an update to SoftDevice or Bootloader but otherwise it is never used in normal operation or during an application update?

We've managed to have our bootloader overlap into the MBR params page and all seems to be working fine with single bank application updates and the application runs fine as does the bootloader. I want to see if we're safe to allow this overlap to persist as long as we do not try to do a bootloader or softdevice update, hopefully the MBR params page is never used outside of the BL/SD update.

Thanks!

Hi Mike,

the MBR params page is used by the Master Boot Record(MBR) to store state information when performing flash operations, i.e. performing swap of the new SoftDevice image and/or Bootloader image. Thus, if you plan on performing any SoftDevice or Bootloader update in the future you must keep the MBR params page.

Best regards
