Hi,I am working with the STM32U5A5QJI6Q microcontroller and need guidance on the programming pins. I plan to program it using [SWD/JTAG (choose one)] with an external programmer like ST-Link.Could someone confirm:Which pins are used for programming via [SWD/JTAG]?Are there any specific configurations or settings I need to enable in the hardware or firmware for successful programming?If using the internal bootloader, what are the required connections (e.g., UART or USB pins)?I am currently working on a project that incorporates the STM32U5A5QJI6Q microcontroller, and I would like to request the official reference design or any relevant design resources for this specific part. Having access to a detailed reference design would greatly assist in ensuring an optimal hardware implementation.Any reference to the datasheet or specific examples would be greatly appreciated.Thank you!Sathiya

Hi,

I am working with the STM32U5A5QJI6Q microcontroller and need guidance on the programming pins. I plan to program it using [SWD/JTAG (choose one)] with an external programmer like ST-Link.

Could someone confirm:

Which pins are used for programming via [SWD/JTAG]?
Are there any specific configurations or settings I need to enable in the hardware or firmware for successful programming?
If using the internal bootloader, what are the required connections (e.g., UART or USB pins)?

I am currently working on a project that incorporates the STM32U5A5QJI6Q microcontroller, and I would like to request the official reference design or any relevant design resources for this specific part. Having access to a detailed reference design would greatly assist in ensuring an optimal hardware implementation.

Any reference to the datasheet or specific examples would be greatly appreciated.

Thank you!
