program doesn't work without debugger

[bondarenkod]

<div>Hello!
I have a problem with VisualGDB.</div>
<div>Couple days ago any programs from VS stopped working on my two demo boards without connected debug.
I tried to test it from 2 laptops – the same result (5.1 (or 5.0) and 5.2 VisualGDB).
With connected debugger program working properly.
Demo application from discovery 429i also working (via hex flashing)/
Here is sample video: https://www.youtube.com/watch?v=SONL2pnnkUE</div&gt;

Hi,

Are you using semihosting in your programs? The way semihosting works would cause the program to stop if a debugger is not attached. Please try making the calls to printf() and other semihosting-related functions conditional so that they don’t trigger in the release configuration.

>>Are you using semihosting in your programs?
yes. But not in this sample and actual post not about problem with semihosting.
Yes, I also have problems with semihosting – in projects with\without mbed. But currently projects with mbed just doesn’t work without connected debugger.

>>the release configuration.
This project just basic project, which created by VisualGDB and doesn’t contains any changes which made by me (only few lines to make leds blinking). I can record step-by-step the process to show you almost everything. Project without mbed is working OK.

Ok, I found that in the project with MBED the VS window called ‘ARM semihosting console’ still empty, but COM Terminal window working perfectly.

Problem #1 – Pending.
Problem #2 – Sovled.

Hi,

Please try updating to the latest gcc 6.3.0-r3 toolchain. We have fixed a problem that might have been causing this.

Yep! Now it’s working as expected! Thank you 🙂
