STM32u599NIH doesn't exist in the board selector tab

[Anassoumi]

Hi guys , I'm currently engaged in a project that utilizes the STM32U599NIH microcontroller. Typically, I would initiate my work by searching for the project under the board selector tab, but in this case, the board is conspicuously absent. While I was able to locate the MCU under its respective tab, I'm unsure how to proceed with fundamental tasks such as UART string printing, which are generally straightforward when starting with a board example project. Could anyone provide some guidance on how to navigate this situation? Thank you.

Perhaps find a donor project under STM32Cube_FW_U5_V1.3.0\Projects\STM32U5x9J-DK\Examples\DMA

Say you have a STM32U599NJ or STM32U5A9NJ device, pretend like the die actually has more flash on it, or it has encryption, and then shrink the size in the linker scripts if you get concerned.

Thanks and is there a reason why initialising uart (for ex) doesn’t work when using an mcu project instead of board example , I still can’t see what differences they have .

I’m currently working on a project with the STM32U599NIH microcontroller. Normally, I would start by searching for the project under the board selector tab, but the board isn’t listed. Although I found the MCU under its tab, I’m not sure how to handle basic tasks like UART string printing without a board example project. Here's the solution: Create a new project in STM32CubeIDE and select the STM32U599NIH MCU. Then, configure the UART by going to Configuration > UART and setting the baud rate, data bits, stop bits, parity, and flow control. Finally, generate the code and use printf to print strings over UART. Any guidance or additional help would be greatly appreciated!
