Not long ago CLion added support for Remote GDB debugging and I'm trying to set it up with Seggers's J-Link GDB server.
- VM VirtualBox running Ubuntu 16.04
- J-Link drivers: V6.10
- Target chip: nRF51 (ARM Cortex M0)
- CLion 2016.2.2
I usually work in windows, but as CLion doesn't support remote GDB in windows I'm trying to make it work running Ubuntu in VirtualBox. I configured the debugger in CLion like shown in the image with a little help from the blog in the link above. The arguments I have used are based on the J-Link documentation (Document: UM08001) and some guessing. GDB server setup
My problem is that when running the debugger the process just stops and CLion's console outputs:
"Could not connect to target. Please check power, connection and settings."
I have tried to run JLinkGDBServer from the terminal and then I get as far as this:
/usr/bin/JLinkGDBServer -device nrf51422_xxAC -if swd -speed 1000 -endian little
