Hi
I am currently testing Buttonless DFU using SDK 12.3, nRF52832 DK.
Example test was conducted first using the DK board, but as you can see in the picture, it will fail. I don't know why.
Is the method wrong?

This file is a log of an issue where only the same log I talked about repeatedly is taken and DFU is not going on. This log is from Nordic's nRF Connect app.
Would you please take a look?

I just found the source of this problem through the nRF Connect utility.
The problem was confirmed that the memory map areas overlap.
The bootloader area overlaps with the application (buttonless) area.
However, I do not understand that these two sources were tested using the original ones, and I do not understand that this phenomenon occurs.
Do you have a solution that you know?
Oh! I solved it.
I didn't know that I had to merge boot.hex and application.hex and download them to the chip in order to set the device to invoke boot mode without a button when the application is up.
I'm working on fixing that issue now and applying source to my project.
But I still can't find a command to call boot mode haha .... ㅠㅠ :(
Instead, the command you gave me seems to help a bit.
Is it right to call boot mode using that part?
I will try more. Thank you.
Hi Aser,
RAM overlapping shouldn't be a problem. The bootloader and the application wouldn't run at the same time. I just tested here and don't see the problem that you are having.
Could you let me know how exactly you flashed the bootloader and the application ? with step by step. For example:
1. Flash softdevice using nrfjprog. (please specify what exact command you used to test)
2. Flash bootloader
3. ....
I attached here the hex files (BL,SD,APP) that I read from my board. You can use this file to test.
I have modified the bootloader so that it by default will jump to the application. The sequence you would need to do with nrfjprog (don't use nrfconnect) is:
1. nrfjprog --eraseall
2. nrfjprog --program .\s132_nrf52_3.0.0_softdevice.hex
3. nrfjprog --program .\buttonless.hex --sectorerase
4. nrfjprog --program .\nrf52832_xxaa_s132_compressed.hex --sectorerase
Please use the exact sequence. If you flash the bootloader before the application you may risk erasing the bootloader setting.
