https://devzone.nordicsemi.com/f/nordic-q-a/51617/debugging-zephyr-os-applications-on-nrf52832-with-eclipse-and-openocdHi, I am trying to set up eclipse + gdb + openOCD for debugging zephyr 2.0.0. applications on nRF52832. Following the official Zephyr documentation build-and-run-an-application and setting my debug configurations in eclipse as shown in the next twoen-USTelligent Community 13Mon, 02 Sep 2019 14:46:39 GMThttps://devzone.nordicsemi.com/thread/207458?ContentTypeID=1Mon, 02 Sep 2019 14:46:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a6df204f-4fef-416c-9ab1-85a14c937910Nguyen Hoan Hoang<p>If that&#39;s the case then your entry point might not be main(). &nbsp;You can to find out in the startup code to see where it jumps to after reset. &nbsp;Since Zephyr is a RTOS, it may bypass the main function. Other scenario could be that you have a miss match in debug info.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207455?ContentTypeID=1Mon, 02 Sep 2019 14:40:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8007d5f0-ab5d-4001-a631-3c6d51c81505StefanHri<p>No, because when I flash the board I can see with my phone that it advertises. This means that the image is OK. I think&nbsp; it is some problem with the debugger initialization.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207453?ContentTypeID=1Mon, 02 Sep 2019 14:35:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe0b6f8f-88cb-4b9f-806b-aa2f33fa5364Nguyen Hoan Hoang<p>Have you checked the startup code as I suggested ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207449?ContentTypeID=1Mon, 02 Sep 2019 14:33:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb325e5a-beba-4493-8200-cb70030ecbadStefanHri<p>I have tried to use JlinkGDBServer also. I noticed similar effects. I can start the debug session (on the console I see that the image is downloaded) but after that the execution never comes to the main().</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207236?ContentTypeID=1Sat, 31 Aug 2019 13:18:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:da62b552-b456-41c0-8eb5-11ed9833a4f4Nguyen Hoan Hoang<p>It looks like you didn&#39;t include the startup code. &nbsp;The reset vector jumped to the wrong location. &nbsp;I am not a Zephyr user so I can&#39;t tell you where to find it. &nbsp;You need to search for it.&nbsp;</p> <p>I see that you are using jlink. &nbsp;It is better to use the GDB JLink instead of OpenOCD. &nbsp;It&#39; s the third one bellow GDB for OpenOCD. &nbsp;Create a debug session with that. It&#39;s faster than using openocd with jlink. &nbsp;Use OpenOCD for other type of jtag probe such as CMSIS-DAP or ST-Link. &nbsp;&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/207187?ContentTypeID=1Fri, 30 Aug 2019 14:11:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:717f9d10-b2f1-4ddc-972f-f253a65dbc77Turbo J<p>You have a jlink debugger. Try using Segger JlinkGDBServer instead of OpenOCD.</p> <p>BTW: It looks to me like your OpenOCD could not write to flash properly -&nbsp; the binary code does not match the symbol information used in the debugger.</p><div style="clear:both;"></div>
