Hey ST,In the FW package that comes with the STM32H7S78-DK, I've been using the Template-XIP project as the base for my own project, and I noticed this issue with the MPU setup of the external SDRAM on the XSPI1 line. Whenver I would try and access m...

Hey All, Similar issue to this previous topic,I'm running into a timeout error every time I try and call USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST from the USB_CoreReset function in the example code. It seems like the previous solution was to make sure...

Sorry for my 3rd XIP post on this board, but the more I learn about this process, the more questions I have. Going through the XIP template code, I think I have a decent understanding of what it does. 1. Set up the XSPI Peripherals, one NOR Flash and...

Previous post here didn't seem to get answered, so I thought I'd ask again.Is there a way to execute code with the XIP framework, but not using the external SDRAM for instruction execution?I'd like to use internal AHB or AXI Ram sections for code exe...

Hey everyone,I'm currently working with the STM32H7S78-DK.I'm trying to set up an external memory loader project, executing code from external memory with XIP, while also partitioning out the SDRAM in a few different addressable chunks in the memory ...

Thank you so much for the reply! For clarity, I am using the stm32H7S78-DK dev kit. The piece of code missing was the voltage regulator step inside of the HAL_MspInit function. I also went ahead and changed my clock configuration around so that my te...

STM32CubeMX has a tool that exports a schematic symbol of your pin assignments. You can check section 4.17 of the CubeMX Manual: https://www.st.com/resource/en/user_manual/um1718-stm32cubemx-for-stm32-configuration-and-initialization-c-code-generatio...

Nice to see you again Pavel, thanks for de-mystifying the process a bit.So, I guess the follow up questions would be:- Is there a way to block off certain areas of SDRAM in the bootloader or application to not be used by XIP? It seems like there is s...

Thanks for the reply,Cool to see that this is possible.So is this what the "EXTMEM_USER" Option is for in cubeMX?From my understanding, you need to set 2 memory sections, one for code storage (external NOR flash, in our case), and one for code execut...
