Hi everyone,
I'm currently trying to flash firmware to a custom board with STM32WLE5CCU6 MCU using the onboard debugger of a NUCLEO-WL55JC1 development board. I'm running into multiple issues and would appreciate any help.
Setup:
Issue Summary:
4. Errors observed in STM32CubeProgrammer:
Additional Notes:
I have attached the custom board schematic below.
Thanks in advance for any guidance!
Let me know if you want me to add or rephrase anything specific (e.g. schematic details, pinouts).

Hello @ruvaispari123gmailcom
On Nucleo STLink-V3 boards it is no more possible to use the STLink for other board because the debug connector is not an "output" for debug (as on STLink-V2-1 boards) but an "input" for other tools than STLink to be able to debug the nucleo target.
Best Regards.
