without bootloader, nordic can work?
i get two nordic board,it work well.but when i read the flash layout
i found that the two board only have softdevice and application. how it work ?
i want to support DFU function, so i erase whole flash
and burn softdevice , applicaiton, bootloader one by one .
to one nordic board it is ok, but to another it doesnot work. the bad board is hanging at the softdevice enable function.
i donot know why. maybe the board's hardware is bad ? but i donot think so..
i want return the bad board to the orign flash layout, but i donot have bootloader, it is tough probem ..how can i fix it .
the origin layout
the new layout,but to one of nordic board it hangs on the softdevice enable functional
