Hi Team i am facing some issue related to flashing code. previously i flashed the STM32Cube_FW_WL Lora wan example code into my stm32wl5cc controller PCB using J-link debugger. after successfully flashed the code i am trying to flash another code into my controller but i am facing issue like Debug access port can't be initialized or target DLL is been cancelled. i noticed that their a function in the source cod like disable debug port in low power modes. because of that function i can't able to access debug ports.
i tried to mass erase the source code but for that also i need to connect debug ports.

please give any solution regarding this issue.

Connect the NRST pin to the debugger or at least try pushing the reset manually at the moment, when the debugger tries to connect.
