Problem in loading the application after dfu

[Pavan kumar]

Hii all

I am trying to port the experimental/bootloader_signing project to gcc I made changes in the project accordingly, so now its working. I can able to flash application from the phone but after that its again start in boot mode. After debugging I come to notice that this if condition fails if (p_bootloader_settings->bank_0 == BANK_VALID_APP) in bootloader.c but I observed bootloader settings are updating while doing dfu. I'm surprising because same code working well in if compiled with keil. Can any one please help me in this regards I'm using nrf51 DK board and SDK9.0.0 and this is the linker script that I'm using dfu_gcc_nrf51.ld

You have to change the bootloader settings address from 0x0003FC00 to 0x0003D800, i.e.

BOOTLOADER_SETTINGS (rw) : ORIGIN = 0x0003D800, LENGTH = 0x0400

and you have to set the BOOTLOADER_SETTINGS_ADDRESS define to 0x0003D800 in dfu_types.h if you have not defined SIGNINGin your Preprocessor Symbols.
