Are you able to upload your project files here so I could try it at my end? If your project is confidential you can create a support case through MyPage on www.nordicsemi.com and refer to this case.

Hi,

I found that fs_flash_page_end_addr which will use the NRFFW[1] and I use sd_power_gpregret_set to write the register. I have delete it and don't do the fs_init, but the bootloader still will disappear when use keil to download online.

Upon inspection of your application hex I have found two lines at the end of the file which writes to the NRFFW[1] register in the UICR region. Specifically the two are :020000041000EA (this is a linear address extension which points to the UICR region) and :0410180000E00700ED (this is where data is written to NRFFW[1]). This indicates that you have not been successful in removing all the code which writes to the MBR. If you're unable to find where in your code this is happening you can try to simply delete these two lines from the bottom of your hex file, and then see if everything behaves as expected.

Thank you for your help. Please see the new attachments I upload.

I have manually edited the application hex you uploaded and deleted the conflicting regions. After this everything works as it should for me, both with mergehex, keil, nrfjprog and nrfgo studio. Could you please upload the new version of your application so I can try with that?

Hi Jørn, Yes, I'm using the buttonless DFU. Now I do as the link you give me, it can merge the files and can program. However it still have two problem. One problem is like the link that the bootloader will disappear when using keil to download application. Another problem is:1-Program the softdevice 3. 2-program the bootloader (At this point the bootloader appears on the nrfgo aplication.) 3-Program the aplication . It's OK just for first time, but if I program the same application again using nRFgo, it will indicatesthe flash is not erased. My application flash and ram setting as follow:

IROM1 Start: 0x1F000 Size: 0x59000

IRAM1 Start: 0x20002CD0 Size: 0xD330

And I do not compile the EDIT 28.10.16 part as the link saidlink text

What reason would it be? Thanks.

Are you using buttonless DFU? If that is the case you might have a problem with both the application code and the bootloader trying to store UICR information in a region of flash reserved for MBR settings. Please see the second part of the answer in the following link: devzone.nordicsemi.com/.../

I have tried it, but it still cann't merge. Even I have tried to change the application code size to 0x50000 or 0x40000

In this case the application goes from address 0x1F000 to address 0x1F000+0x61000=0x80000, so you see the final address of the application lies inside the memory allocated to the bootloader which starts at 0x78000. Try changing the application code size to 0x59000 (=0x78000-0x1F000).

Alice — Tue, 07 Mar 2017 12:42:45 GMT

I haven't change anything about the IROM1 and the IRAM1 in the Keil->Options for Target->Target. Application: IROM1 start 0x1F000,size 0x61000 Bootloader: IROM1 start 0x78000, size 0x6000

Do I need to change it? But I donn't know how to allocated memory size for the application code.

Jørn — Tue, 07 Mar 2017 12:22:32 GMT

I was a bit hasty in my original answer, the conflict does not lie between your application code and the softdevice, but between your application code and your bootloader. They both try to write to the same address location, line 3120 in your application code hex and line 1431 in the bootloader code hex. This can occur if the flash address for application start + allocated size is greater than the bootloaders start address. You should check whether or not this is the case, and change the allocated memory size for the application code if there is a conflict.

Hi Jørn,

Thanks. Please see the files upon.

Jørn — Tue, 07 Mar 2017 07:26:47 GMT

I am able to program the hex file you uploaded with nRFgo studio, after programming the softdevice, just fine. Could you please upload the rest of your files so I can try to retrace your steps?

Hi Jørn,

The hex file can merge the S132 softdevice, but it cann't merge the bootloder file. I have read the link you give me and I still cann't solve the problem. Could you tell me how to solve the problem and merge them in detail? Thanks.

Hello Alice

This error can arise when addresses in the hex files you are trying to merge overlap. In your case the address stated in line 1 of your file matches the one in line 3993 of the s132 softdevice hex.

Please see the following links:
