Hi, while switching to the nRF Connect SDK, I cannot program anymore my ANNA B112 (which is a nRF52832) using my nRF52840-DK as a programmer. The following are working: Flashing and reading the program from the ANNA B112 with VS Code and SES using the new SDK Debugging the ANNA B112 with Segger Embedded Studio with the nRF 5 SDK Debugging the nRF52840-DK directly with VS Code and SES using the new SDK When I attempt to debug with the new SDK on the ANNA B112, the debugger goes to cpu_idle.S and stays there. That's with many projects, including projects that are in production now, using a ANNA B112. Thanks in advance,

Cannot debug ANNA B112 with nrf52840-DK as Jlink

Hi,

while switching to the nRF Connect SDK, I cannot program anymore my ANNA B112 (which is a nRF52832) using my nRF52840-DK as a programmer.

The following are working:

Flashing and reading the program from the ANNA B112 with VS Code and SES using the new SDK
Debugging the ANNA B112 with Segger Embedded Studio with the nRF 5 SDK
Debugging the nRF52840-DK directly with VS Code and SES using the new SDK

When I attempt to debug with the new SDK on the ANNA B112, the debugger goes to cpu_idle.S and stays there. That's with many projects, including projects that are in production now, using a ANNA B112.

Thanks in advance,

Yes, I am using the nRF Connect for desktop app, and the toolchain manager. I tried launching VSCode both from the toolchain manager and the start menu.

The cortex-debug version is v1.2.2.

The method to leave the option unchecked and pressing F5 doesn't work, as it never reaches my breakpoint in main, but it stops at random other files.

In VS code you have to manually add the symbol (.elf) file in the debugger console (SPM as example here):

add-symbol-file my-build/spm/zephyr/zephyr.elf

vscode does not load symbols for multi-image projects (mcuboot, spm, b0 etc) so this could be te issue you are seeing.

It still never reaches my breakpoint in main.

That's what I get in my console.

Stil not able to replicate the issue, but could see if the issue stil presist if MCUBoot is not included. It might be a trigering factor for the issue you are seeing.

Can you test with a different NCS tag like 1.7.0 to see if the issue still occurs. Can you give me an example that consistently fails to debug.

I tried 1.7.0 for the NCS version. Tried disabling MCU boot.

The example is hello_world. The board is a BLE8 Click by Mikroe electronics. It has a ANNA-B112 and we use it as a dev board for the the ANNA-B12.

This is my wiring and connection to the nRF52840-DK. In the SDK, I have tried a custom board that we use on our production ANNA-B112 boards, the ubx_evkannab1_nrf52832.
