FMC_SDRAM example isn't Loading to STM32H750B-DK

[Caan]

The STM32H750B-dk Based Custom Board isn't entering debugging mode when using STM32CubeIDE . But QSPI Example Code is working perfectly.

[TDK]

If the FMC settings are bad, the debugger won't be able to connect.

Does the program work in non-debug mode?

 

Consider putting in HAL_Delay(1000) prior to any FMC initialization, setting a breakpoint there, and stepping through.

When Downloading the binary directly into the Board same error Shows up.

Hello @Caan ,

In fact, you need to follow the procedure described in the readme file.

For CubeIDE, you need to use STM32CubeProgrammer tool to handle the external QSPI flash:

From th read me file:

In order to make the program work, you must do the following:

1. Select required configuration in memory.h in Templates\ExtMem_Boot\Inc template.
The default configuration is:
- DATA_AREA set to USE_INTERNAL_SRAM
- CODE_AREA set to USE_QSPI
2. Program the internal Flash with the ExtMem_Boot (see below).
3. Program the external memory with this example (see below).
4. Start debugging user application or reset for free running.

In order to load the ExtMem_Boot code :
- Open your preferred toolchain :
- Open the Project
- Rebuild all files
- Load project image

In order to load this example to the external memory:
- Open your preferred toolchain
- Open the Project
- Use project matching ExtMem_Boot selected configuration
- Rebuild all files:
- Run & debug the program:
- For an XiP configuration (eXecute in Place from QSPI):
- Using EWARM or MDK-ARM : Load project image from the IDE: Project->Debug
- Using STM32CubeIDE :
- Open the STM32CubeProgrammer tool
- Select the QSPI external flash loader "MT25TL01G_STM32H750B-DISCO" in case of XiP from QSPI
- From Erasing & Programming menu, browse and open the output binary file relative to your application
- Load the file into the external QSPI flash using "Start Programming" at the address APPLICATION_ADDRESS (0x90000000).

Then run a debug session from CubeIDE.

Hope that helps.
