when programming Application, there is no request for erase memory. why programming Bootloader requeset erase flash memory? how about Soft Device?


I'm using nRF51. SDK11.

Can I program Application+BL+SD (merged to one hex with mergehex.exe) without remove pstorage page?

there is a memory area no t want to erase.

  1. Which program are you using to program? What do you mean by "no request for erase memory"? Are you talking about an eraseall? Erasing the complete flash? What are you trying to achieve?

  2. What do mean by without remove pstorage page? A flash page that have been used an old application with pstorage? Do you mean DFU or normal programming?
