Can I remove MBR parameter storage area?

[JohnCC]

Hi,

        I want to remove MBR parameter storage area(0xFE000 to 0xFF000). Because we have code size problem.

We have our own spi bootloader to get new application and settings from external flash. 

In my mind,

Bootloader settings in 0xFF000 to 0x100000

Bootloader in 0xF2000 to 0xFF000.

Application in 0x31000 to 0xF2000

Softdevice in 0x1000 to 0x31000

Master Boot record in 0x0 to 0x1000

Is the original MBR parameter storage just used to store bootloader settings backup? How to delete it if we don’t need it?

Thank you.

John.

Hi,

Which version of the SDK do you use?

See  Error bootloader when use MBR parameter storage as application data area . Does this answer your questions?

Hi Sigurd,

      I use SDK17.0.2 and nrf52840.

In our bootloader, I don't use any DFU function. My update image from external flash by SPI.

Thank you.

John.
