Hello Forum, The title sums it up. I have a minimal project on a STM32 target (STM32F769I), along with J-Link base connected over JTAG. I have a printf call and this seems to cause some linking issues. I'm using GCC and a custom linker and startup files provided by STMicroelectronics with their HAL Drivers. Thank you !
