Hi,

Sorry for the bad link. We at support don't recommend using dynamic memory allocation since there is a high risk of getting issues related to unsafe allocation algorithm or fragmentation. "Don't use at all nowadays', is the way to go!

Best regards

Hi. Thanks for answer. I can't open second thread you linked to, says "it's private get out of here")).

From first thread If understand correctly use nrf_calloc or nrf_malloc instead of native C functions (calloc, malloc) technically will not bring any problem with fragmentation and memory leak.

But the main question is

If I am sure I don't approach even half of whole nrf52840 ram should I think about dynamic allocation (nrf_calloc)?

Hi,

The usage of dynamic allocation has been discussed before in this forum. I suggest that you see the answers in this thread and this.

Best regards
