Hello,
I'm working on a project where I'm using an STM32H7R3L8H6H and an MX25UW25645G. It isn't possible to get the Flash working on XSPI2 when using the ExtMemLoader generated by STM32CubeMX. I checked the example in the firmware package and found the following errors in it:
- In the STM32CubeMX XSPI2 configuration, "Parameter Settings" is the "Memory Size" with 32GBit selected.
- The "__FLASH_SIZE" in the linker file "STM32H7S3L8HX_ROMxspi2_app.ld" is set to 0x08000000.
Since the NUCLEO_STM32H7S3L8 board is using the MX25UW25645G chip, those settings are incorrect.
They should be 256GBit instead of 32GBit and 0x02000000 instead of 008000000.
Where can I find the source code for the "MX25UW25645G_NUCLEO-H7S3L8.stldr" which is shipped with the STM32CubeProgrammer? It looks like this loader is working, but I want to use my own loader for my project. Unfortunately, there is not one working example anywhere that uses the MX25UW25645G, even if this chip is used by STM on their NUCLEO board.
It is very frustrating and time-consuming to work with the STM32H7RS series MCUs.
The STM32H7RS series MCUs are very powerful devices, but with this kind of lagging support, it becomes very frustrating and time-consuming to implement these devices in any design.
keep moving and never forget:
