   Hi Diego, thanks for your feedback. This config enables the CONFIG_STM32_DFU config so it requires a bootloader and the image is not mapped to 0x8000000 as usual. Maybe this is the issue if you are flashing using JTAG. Can you share more information regarding the flashing method you use ? Can you disable STM32_DFU if you use JTAG ?
