0.28.2 pyocd-gdbserver crashing? #996

Closed Microsparky closed 3 years ago

Microsparky commented 3 years ago

Hello,

I am trying to set up a development environment using VS code, cortex-debug, arm-none-eabi and pyocd.

When I start debugging with cortex-debug I get the following output:

VS Code popup:

Failed to launch GDB: Remote communication error. Target disconnected.: No connection could be made because the target machine actievly refused it. (from target-select extend-remote localhost:50000)

Debug Console:

Please check OUTPUT tab (Adapter Output) for output from pyocd-gdbserver

I ran netstat -a and found no open port 50000 so I figured pyocd-gdbserver had not started the server, I tried to run the same command cortex-debug was using -d debug to get more information. I get the output below then after 4 or 5 seconds the prompt returns.

I don't know where to go from here, did pyocd-gdbserver crash? What can I try?

pyocd gdbserver works as expected and doesn't return to the prompt

Hi @Microsparky , this is a known bug that's fixed on the master branch. Version 0.28.3 with the fix will be released shortly.

Closing as a duplicate of #990.

Thanks @flit I will try install directly from the source. Sorry I didn't find the other issue

flit commented 3 years ago

No problem! The other issue wasn't particularly clear since it referenced Eclipse in the title.
