Hello, thank you very much for the quick answer, and the link to the tutorial ! As I understood, as first (to have the menu point ‘additional memories’) I have to upgrade to VisualGDB Custom Edition (I started with Linux Edition) ? And then .. pity .. my base intention was, to be able to set brakepoints in the code that is executing in the QSPI memory. But as I understood from tutorial, this is not possible ? Regards
