STM32CubeMX and STM32CubeIDE can't get NUCLEO-H7S3L8 board to work

[Intector]

Hello,

Nobody at STM seems willing to answer my questions to the NUCLEO-H7S3L8 board. I've two of those boards and spend much time with them, but nothing will work. None of the examples from STM32CubeIDE can produce any results with those boards.

I wrote several posts here in the community but got only an answer to the first one. I even offered money for help, but it's almost like I got blacklisted.

There is no helpful information about the STM32H7S/R series on the Internet, which is somewhat frustrating. I'm thinking about posting my questions and experiences with STM elsewhere, and maybe I can get help elsewhere.

Never forget:

Hello @Intector and you are welcome and you are not blacklisted :).

Could you please describe your issue with the NUCLEO-H7S3L8 board?

Did you try the examples provided in STM32H7RS Cube package? read the corresponding readme file before? :

Hello SofLit,

Thank you for the answer. I've been working with STM32 MCUs for quite some time now and have to say that I like them for many reasons. The STM32H7RS series caught my attention at the Embedded World in Austin, TX. I've noted those MCUs before but never showed any serious interest until I encountered a memory shortage in one of my projects. This project was initially started with the STM32H753ZI MCU and utilized quite a bit of AZRTOS. The integrated HTTP and FTP servers use an EMMC08G-MV28-01J10 for their content, which works very well. The RAM shortage becomes visible when I try to add my IO-Link driver(I've attached some pictures of my EMMC board).

This led to the decision to use an MCU capable of controlling external memory. The STM32H7RS MCU, with its XSPI interfaces, would be the perfect candidate for this project. I got two of the NUCLEO-H7S3L8 boards to test things out. Unfortunately, I could not get anything to work on those boards. I tried unsuccessfully several STM32CubeIDE examples, as described in their documentation. I'm unsure how much time I spend finding detailed information on the internet regarding the STM32H7RS MCUs. 

Here are a few of my questions:

• If I start a new project in CubeMX and select the NUCLEO-STM32S3L8 template, the boot project's icon has a warning sign. What does this mean?
• What and in which order do I flash the firmware to the board?
• How can I just flash the application project to the address 0x70000000?
• Is there a more detailed description of which parts of the software must be in the boot or apps sections? 
• Do I have to initialize the AZRTOS in the boot or the app section?

The NUCLEO-STM32S3L8 boards are back in their boxes, waiting for the time when sufficient information will be available. 

I started working on a new PCB for the STM32H723ZG with APS6408L-OBMx and EMMC08G-MV28-01J10.

Hello @Intector 

Below 3 Wikis giving introductions and practical examples to use in the following order.

• Getting started with External memory Manager and External memory loader: Getting started with External memory Manager and External memory loader - stm32mcu
• Introduction to External memory Manager: Introduction to External memory Manager - stm32mcu
• Introduction to External memory Loader: Introduction to External memory Loader - stm32mcu

The AN6103: Introduction to external memory manager and external memory loader middleware for boot flash MCU, gives details information on how to start the development on the STM32H7R/S series.

Best regards
