​Hello.

I am looking for example of External Qspi Loader for the Stm32h743.

I manage to make my functions work. but not to create the .stldr

I have the impression that he does not take Init.

I am under Stm32cubeide.

thank you

Hi @cVass.1​ 

You can refer to available QSPI examples with STM32CubeH7 firmware: STM32Cube_FW_H7_V1.6.0\Projects\STM32H743I-EVAL\Examples\QSPI

thank you,

but no example to create an External Loader.

On my tests I must do a Disconnect and Connect to manage to put in Mapping.

You can refer to application note "Quad-SPI interface on STM32 microcontrollers and microprocessors" AN4760

Hi cVass.1

I'm struggling with the same problem. I've created required functions, tested them in the stm32cubeide and everything looks OK. I managed read and write an external flash (1M). Then I added Loader_Src.c and Dev_Inf to the project and built it with the linker (please find attachment). I got .stldr and copied it to the appropriate folder of the STM32CubeProgrammer. Now I can read the external flash by STM32CubeProgrammer, but unfortunatelly cannot erase and write. The error message says: failed to erase memory... Please let me know if you have some progress.

Thanks

Hi @cVass.1​ 

Can you share your project and the target memory's datasheet?
