Hello all,

I am using the STM32 Workbench Version: 2.0.1.201705161428 on Ubuntu 14.04.5 LTS with OpenOCD version 0.10.0-dev-00278-ga53935e-dirty from the same version of the debugging tools.

If my binary size is smaller than 10164 bytes I can debug my project if it is larger I cannot.

Here is the -d2 output of the small binary (successful) debugging:

And here is with a larger binary (failing) debugging:

If I increase the debug level to -d3 I see the following output before the termination:
