Hi
It is for a custom board based on the STM32H563 MCU.
All the NRF configurations uses the SOC_NRFxxxx to select the CONFIG_TFM_BOARD, which I think is a more generic way as it is the MCU and not the actual board that sets the TF-M options and limitations.
But if you prefer to use the nucleo_h563zi to select the CONFIG_TFM_BOARD, then it is relatively simple to set it for custom boards. This can be done by adding config TFM_BOARD default "stm/nucleo_h563zi" In my custom board's Kconfig.defconfig file
Best Regards Mogens

Hello,
For a better understanding of your request, on which board (ST Nucleo or your design) you need to port STM32H563 MCU ?
Thank you
Ronan

Hello,
As it’s the first time we (ST TFM team) have this request, we are checking internally with managers and marketing and will come back as soon as possible.

Hi
Is there any plans to include the STM32H563 as a supported TF-M platform ?
If I clone the existing STM32H573_DK and adapts it to the STM32H563, what is then the process to get it upstreamed ?
Med venlig hilsen / Best regards
