[SOLVED] I cannot flash and use the QSPI W25Q128J chip on the new STM32F746G-DISCO version C03

[Ciuffoly www.audiodesignguide]

I have develop a program on STM32F746G-DISCO revision B02 with QSPI  N25Q128A13EF840E

Now the new boards revision C03 use the QSPI W25Q128JVEIQ.

I have copied the file W25Q128JVEIQ_STM32F746G-DISCO.stldr from CubeIDE 1.16 to the STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader but the external loader is not flash.

I need to change some in my code to use this new QSPI chip ?

The BSP initialization, STM32 side, will need slightly different code to work into 4 pin, 4 bit operations. The commands and status registers between the Micron and Winbond are subtly different.

Code for the images to work needs to get the memory IC into memory mapped mode, and you perhaps need to verify you can read the content and that that matches expectations. 

I'd perhaps use a CRC as a quick check of integrity. ie data built on host matchs data visible on the target.

but still no images loaded from QSPI

To me this is no more an issue with the external bootloader. It's something related to QSPI inti in your application.

I invite you to close this thread and open an new one for the second question.

I have found an information about this problem so the action to solve is here:

1) download the last driver in the en.stm32cubef7-v1-17-2.zip archive with inside the w25q128j.h file

2) put this w25q128j directory inside \Drivers\BSP\Components

3) save previous stm32746g_discovery_qspi.c and stm32746g_discovery_qspi.h

4) copy new files stm32746g_discovery_qspi.c and stm32746g_discovery_qspi.h from ...v1-17-2.zip archive

5) add in the MCU GGC Compiler Preprocessor define the    USE_STM32746G_DISCO_REVC03

6) recompile

Now also ST-LINK work !

you can also use the cube programmer to read the external flash to see if the image is really loaded into the external flash
