hi everyone,

why I'm getting this error?

>>I called the qspi.c & .h and added an MPU at the @0x90000000, added the BSP into QSPI_init()

Ok, but that is all C side implementation code.

The error looks to be linker, or downstream the code converting it to a .BIN file (objcopy). Uncheck "Make .BIN" or whatever the IDE option is there.

Perhaps you can avoid generating a .BIN as it will be huge, try creating a .HEX instead, as this can be sparse (holes between different memory regions)

>>I copy the code from a file that was generated by TouchGFX, when I build the other one it works but mine doesn’t work, this is weird!

Review the project meta-data, describing the link/build options, and how they differ. Find an example project using QSPI that works.

Probably some sequencing order in the .LD, too late in file and having earlier matches, or attempt to copy out of internal flash.

I guess you'd review the .LD and modify it. I can't see your file from here.

Perhaps DIFF your implementation against this one

STM32Cube_FW_F7_V1.15.0\Projects\STM32746G-Discovery\Examples\QSPI\QSPI_PreInitConfig\SW4STM32\STM32746G-DISCOVERY\STM32F746NGHx_FLASH.ld

@Community member​ , I copy the code from a file that was generated by TouchGFX, when I build the other one it works but mine doesn’t work, this is weird!

I called the qspi.c & .h and added an MPU at the @0x90000000, added the BSP into QSPI_init()

What can you suggest bc I really need this! my code is overloading the flash & im getting an error with this! I have 32Ko out of flash
