glitching on STM32F413-Discovery

Question

Hi, I've been working on a project for STM32F413-Discovery and it suddenly started glitching like on the picture below, commenting any change I've made right before it started didn't helped. I can compile and upload earlier version without glitch, but I would love to find out the cause to preserve my changes. Any tip on how to debug this?

Best regards,

Pavel

Hello,

are there any messages on the console output that could help to find the root cause?

Best regards,

Ok, so you find the answer in the first error message: Out of memory.

The system does not provide much memory - the current memory pool is configured to 120 kByte.

You can check the memory usage of your GUI application within the RAM usage window of Embedded Wizard. For more information see also the chapter Memory Footprint.

I hope this helps...

Best regards

Manfred.
