Own custom build STLDR file creation issue

[MMARI.1]

hi,

I am trying to build my own STLDR file with STM32H723ZGT6 + w25q128.

I could able to build the stldr file STLDR creation with Separate Project 1 but it's not working with external loader  project 2 it's giving down load error while program download  .

Note : i could able work with external loader Project 2 by using https://github.com/cturvey/stm32extldr/tree/main/h7_w25q128  not by my made STLDR file.

I have referred some existing STLDR creation project with STM32H7B0 + w25q128 found they used 

 

void SystemClock_Config(void)
{
 RCC_OscInitTypeDef RCC_OscInitStruct = {0};
 RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

 /*AXI clock gating */
 RCC->CKGAENR = 0xFFFFFFFF;

 

 why they have (RCC -> CKGAENR = 0xFFFFFFFF )gating the AXI clock ?. 

STM32H7B0 reference manual:

STM32H723 reference manual:

how to gate the AXI clock in STM32H723 ?

You can run the part from the initial HSI (64 MHz)

You only need to enable the relevant OCTOSPI and OCTOSPIM peripherals, and pins related to the interface

hi, 

i have enabled HSI (64 MHz) with single quad spi in octo mode and made many attempt to successes but nothing happen !. I have attached the stldr creation project (zip). Please give me the  idea about what is missing  ? . The exact error message as below  while downloading via cube ide .

hi,

Using my own build STLDR file, I could able to down load the dummy binary file via cube programmer as well as erase and read functions with external loader .

But i could not able down load the elf ( main code ) file via cube programmer and cube ide debugger.

From the above analyze code's  are fine . i think cube programmer and cube ide debugger not catching the elf file but i don't know how using  the  https://github.com/cturvey/stm32extldr/tree/main/h7_w25q128   stldr file  is working fine !.
