Just to be more specific. I know that if this was stackoverflow I would get -1Meg for such a question, though there is no safe space. So I have the same cfg file for both projects which looks like that:

”# This is an EMCT_Display_V2 board with a single STM32F303VETx chip.”
”# Generated by System Workbench for STM32”

source find interface/stlink-v2.cfg

set WORKAREASIZE 0x10000
transport select “hla_swd”

set CHIPNAME STM32F303VETx

source find target/stm32f3x.cfg

”# use hardware reset, connect under reset”
reset_config srst_only srst_nogate

Then for the case where the loading is not working I got the following response:

For the project where the loading is successful it’s looking like that:
