Hi!
We are using a custom bootloader for our device. Current version of this erases everything from 0x0 to bootloader start address, and then writes MBR + Softdevice + application. This works fine, however we are not comfortable with erasing the MBR, bricking the unit if it experiences a reset before writing the new application.
From what we understand, the MBR is written to the first sector, so we could just skip the first sector when erasing. However, this means that we must trust that the MBR is identical for future softdevice versions, is this correct?
