I wanted to upload/flash code on my STM32H753zi MCU using external ST-Link ....how to bypass the onboard st-link connections

Just for clarification for the community members who have not read your previous posts: an STM32H753ZI is an MCU and does not have an onboard ST-LINK.

What you mean is a NUCLEO-H753ZI, for which there is a detailed user manual UM2407, and in section 6.3.3 this exact case is described: “Using an external debug tool to program and debug the on-board STM32H7”.

Hope that answers your question?

Thanks for replying, As I have already mentioned that I want flash my code in STM32H753ZI IC onboard and want to bypass ST-link which both are on Nucelo-H753ZI on board, So I want to ask how can I bypass it?
