Eclipse doesn't send halt to GDB stm32F1 project (SOLVED) [message #1753493]

Good day,
I updated eclipse to Neon.2 Release (4.6.2), CDT and gnuarmeclipse to latest build. And now when I debug stm32f1x project, I can't pause program executing. But when I connect via telnet to openocd, if i write halt, program suspends. So, it looks like, that eclipse doesn't send halt command to openocd.
Can you advice me, where to look at t fix it?

Obvious stuff first:
1. See if it is specific to your program or an issue for anything running, e.g. main() { while(1); }
2. See if other debug commands work, e.g. step, set BPs, run?

I'm not familiar with the inner-workings of gnuarmeclipse, but I would do the following steps to debug the problem:
See if GDB->OpenOCD works OK without Eclipse. I.e. start OpenOCD, connect with GDB and see if you can pause by pressing CTRL+C in GDB and can debug normally.
Check the Eclipse integration:
1. Add "-d" switch in "OpenOCD Setup" > "Other Options" to enable verbose debug dump.
2. Specify the LOG file in "OpenOCD Setup" > "Log file".
3. Inspect "GDB traces" Console view before and after pressing the "pause" button. Check OpenOCD LOG to see that it got the halt request from GDB.
4. Check Eclipse LOG for any exceptions related to debug (<workspace>/.metadata/.log)

Hi Alex,
thanks for answer.

A)
1. there no something like main() { while(1); }
2. Everything else work fine (step, set BPs, run), but it can't create BP after I run program. But maybe, because it can't halt core.

B)
when I start openOCD and GDB manualy from console it works fine and CTRL+C pause program.
I'm not sure if I can pass CTRL+C from debugger console in eclipse.
1. I did -d 3 in config options and now have a lot of debug information, but completely nothing happens when I click pause
2. I can't see "Log file" field in openOCD setup pages, or i shoud use some linux ">" stream operator? Anyway, I see debug information in console and when I click pause, nothing happens
3. Can you please tell more, how to get to GDB traces?
4. There's my Eclipse LOG

Hi Alexander,

This sounds a lot like a known problem in CDT 9.2, See Bug 509812. It is fixed for 9.2.1 released in a month or so. Your choices are to downgrade CDT to 9.1 or to install the most recent, but unreleased, build of 9.2.1: https://ci.eclipse.org/cdt/job/cdt-9.2/lastSuccessfulBuild/artifact/releng/org.eclipse.cdt.repo/target/org.eclipse.cdt.repo.zip

I hope that helps,

Jonah
