I have a customized pcb with stm32l476 as the mcu and stm32f103 as a debugger. Since my debugger is not flashed i am using an external st-link from the nucleo-l476. When i try to connect it in the normal mode and reset mode, STM32 Cube Programmer gives me an error that DEV_TARGET_HELD_UNDER_RESET and when i try to connect it in hot plug mode, it connects but gives an error that NO DATA READ. What should i do?
