STM32H750vb External Loader issue with W25Q128JV

[JP_RS]

Hi , I am trying to develop the external loader for W25Q128JV flash interfaced with STM32h750vb through QSPI. I have tested each function for its operation in STM32CUBE_IDE.

But i am not able to get the External loader to work it cannot read write or erase.

the peripheral are initialized as

  PE2   ------> QUADSPI_BK1_IO2

  PA1   ------> QUADSPI_BK1_IO3

  PB2   ------> QUADSPI_CLK

  PB10   ------> QUADSPI_BK1_NCS

  PD11   ------> QUADSPI_BK1_IO0

  PD12   ------> QUADSPI_BK1_IO1

I also am not able to understand how the stmcube programmer calls the functions in Loader_Src.c file.

also when i use external loader to load program at the external flash i get the following error.

Error: failed to erase memory

Encountered Error when opening C:\ST\STM32CubeIDE_1.5.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_1.5.0.202011040924\tools\bin\STM32_Programmer_CLI.exe

Error in STM32CubeProgrammer

Debugger connection lost.

Shutting down...

Am i missing something please advice?

Thank you for your time
