Would it be possible to debug/program another PCB including an STM32 MCU with the debug connector provide on the Nucleo-G474RE? (I don't have an external programmer yet)
What would you recommend for future designs. add a JTAG connector on the PCB and always flash the STM via the JTAG or create a bootloader and do it over USB? I guess if I want to want to flash a bootloader in the STM, I will need the JTAG connector anyway, so the USB connector will only cost me space on the PCB. Or is there another way to load a bootloader?
