Eclipse debugger hangs up with "Starting target CPU..."

[Rabbi]

Hi!

I have been following this process to develop using armgcc and Eclipse: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/development-with-gcc-and-eclipse

So far, I have successfully run the blinky code. However, when I am trying to run the code in "examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput" directory the debugger hangs up with "Starting target CPU..." (image attached). 

I am using nrf52840 DK, SDK version 14.0.0, GCC Toolchain 4.9 and JLink 6.40. 

I have followed the solution stated here: https://devzone.nordicsemi.com/f/nordic-q-a/15253/debugging-problem-with-gnu-arm-eclipse-toolchain-nrf52-blink, but the problem has not resolved. Any comment would be appreciated. Thanks!

Did you remember to flash the corresponding softdevice first?

Thank you for your response. Yes, I did.

Hi Rabbi,

It is a little bit hard to say what the issue is. 
It could be that you have set a breakpoint in main(), if you could show the CPU registers it could be easier to see if the code is running normally.

However, I would highly recommend that you upgrade to SDK version 14.2 or newer since there it is introduced SES IDE support for free which in my opinion works a lot better than Eclipse.

Also, the support is much better with using SES with nRF52x products.

Best Regards,
