Problems flashing the DFU on the Eval Kit

[Locky]

I am using the GCC DFU project provided by Nordic on GitHub (devzone.nordicsemi.com/.../)

I altered the main.c to trigger to DFU mode based on the contents of the GPREGRET register rather than Button 7. However when I try and Flash the .hex file (bootloader_gcc_xxaa.hex) of the project on nRFgo Studio I get the follow error. The hex file has data in SoftDevice region. Try programming using "Program SoftDevice", or erase all before programming.

Can I (,how can i) alter this project to not reside in the SoftDevice region or do I have to fully integrate it with the SoftDevice (7.0.0) .hex?

Thank you for your help.

P.S. I am using rRFgo Studio 1.17.1 to flash

nrf51_bootloader_gcc-master.zip

I compiled your project and was able to successfully flash it to nRF51822. I had to clean the project first.

I was also able to reproduce the error you got. It happened when the "Makefile.common" and "gcc_nrf51_s110_bootloader_xxaa.ld" was not copied to the folder nrf51822\Source\templates\gcc. (These files are included in the GCC DFU project you found on GitHub)

The .hex file should be called "bootloader_gcc_s110_bootloader_xxaa.hex" when the right linker script is chosen.

Could you try to copy your DFU project in to a fresh install of the SDK under the "device_firmware_updates" folder , and copy in the linker files to the template/gcc folder? Then in eclipse, import you project as a Makefile project and add /gcc to the build directory. This is what I did at least.

There is also a .map file in the Build folder, could you send me this file for both the DFU and the Application, so I can check and see what went wrong during the linking?

Just to check, the application has to be flashed through the bootloader, if you are using a bootloader, not in nRFgo Studio.

Could you send me you app .hex file so I can test it?
