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

[Ciuffoly]

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 ?

Hello,

Why are you still using STLINK Utility? Please use STM32CubeProgrammer instead.

 

[Tesla DeLorean]

The ST-LINK Utilities have been deprecated for many years, there could be some issues with how the loader initializes or its size.

I should have some F7 W25Q128 loaders that work in this context. 

[Ciuffoly]

I need only to add this on  STM32CubeProgrammer   ?

 

 

 

[mƎALLEm]

Why are you needing to copy the External loader? It's already available:

 

[Ciuffoly]

ok, I am using the STM32CubeProgrammer with External Loader but still not see the images stored on QSPI.

 

Soon I will update the log of flash phase

 

[mƎALLEm]

Did you succeed to Flash the external NOR flash with CubeProgrammer or not?

but still no images loaded from QSPI

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.
