I am using Nordics sample bootloader and I really want to make sure that given a freak accident in sending it the firmware or in the firmware code itself that the bootloader is never erased or overwritten. In its current state, is the bootloader protected against that or are there measures I can take to accomplish it?
I have also noticed the call sd_flash_protect, but I am not sure if that is the proper approach and if so how to use it.
Thanks,
