The problem: no source available at 0x0, when debugging on nRF52

[Mian]

Hi,

I'm a beginner. I downloaded nRF5 IoT SDK, and tried to run and debug the application "publisher" on nRF52 platform. And each time, I got a message "no source available at 0x0". And here is the picture:

Could anyone please tell me how to fix this problem?

Thanks a lot.

Hi,

I'm trying to 100% follow the instructions in this guide. But there are some difference due to the different version of eclipse. I have another project which is proximity. It works well with debugging step by step, and get connection with my iPhone.

Right now, I switch to IoT mqtt publisher project. Thank you for reminding. I didn't program the required softDevice. And I did it with nRFgoStudio, only updated SoftDevice. The file name is "s1xx-iot-prototype3_nrf52_softdevice.hex". It displays "programmed successfully" in log window. And in "Region 1 (SoftDevice)", it shows below:

Size: 124KB Firmware: Unknown (Id: 0x006f)

Is that correct? and I still cannot debug the "publisher" project. It says below:

No source available for "main() at 0x282cc"

or

No source available for "(gdb[2].proc[42000].threadGroup[i1],gdb[2].proc[42000].OSthread[1]).thread[1].frame[0]"
