Francesca, several things may have changed since this question was posted 2 years ago, so I suggest you make a new one. You can of course link to this thread in your question. When you post the question, remember to include details about your setup (SDK version, if you use Segger Embedded studio,etc) and a bit about what you have tried thus far.

Please try the \nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac\examples\thread\cli\usb_bootloader example without modifying anything (ie you can change the board define but is not necessary) . The usb_bootloader variant is configured to run with the pre-programmed bootloader. I was not aware of this when I wrote the previous reply.

We are probably using different version compiler versions, or optimization settings. I don't think the minor size difference is related to the issue.

I made the changes to the files in the project you mentioned, changed the preprocessor definition from BOARD_PCA10056 to BOARD_PCA10059 rebuilt the project and then flashed it to the dongle. For some reason it does not work. I tried the hex file you included and it works fine. Is there any other change to the project I missed? I checked the flash layout for both files and I saw that for the App section, yours goes from 0x1000 to 0x47598 and the one I got goes from 0x1000 to 0x475B0

Hello,

The dongles do not have an OB segger so needs to be programmed through USB DFU using nrfutil or the programmer app in nrfconnect.

I did a quick test with the cli example (nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac\examples\thread\cli\usb\). Below are the changes I made. Same approach should work for the other examples as well.

devzone.nordicsemi.com/.../flash_5F00_placement.diff

devzone.nordicsemi.com/.../emproject.diff

CLI example with modified linker settings:

devzone.nordicsemi.com/.../thread_5F00_cli_5F00_usb_5F00_pca10056.hex

Hello! Vidar, Berg i would love instructions.

I have the latest version of nRF Connect and Segger with Thread&ZigBee 2.0 library and J-link.. The example for thread works just fine on 10056, but with 100059 i get the same error message and Timo Jansen on nRF Connect.

I can compile the thread example for nRF DK with segger too, but for the dongle Segger gives "No j-link support" error".

Thanks in advance.

Hello Timo,

You need to update the linker configuration so that the application does not overlap with the pre-programmed bootloader and MBR. If you are unsure how to do this, let me know what toolchain you use and I'll update the answer with instructions.
