STM32F7_Discovery not loading Demo images.

Hello ST community,

I have download latest version of STM32Cube for F7 mcu and I can easily compile the demonstration project using Keil. But the program seems to have no access to images (I figured out that this has something to do with the image storage location).

If I remove the lines:

&sharpif defined ( __ICCARM__ )

&sharppragma location=''ExtQSPIFlashSection''

&sharpelse

__attribute__((section(''.ExtQSPIFlashSection'')))

&sharpendif

Located under k_startup.c I can see the loading image (corresponding to that file).

Any clues on this topic?

Thanks in advance!

Hello PStark,

you must use ST-Link V3.7 to program the QSPI-Flash.

Hi,

I just received my STM32F7 Disco, I tried to compile the demo program using IAR EWB and Keil MDK 5 but with no success; due to the large code size which exceeds the limits permitted by the kick-starter and evaluation version of both IDEs.  

However I managed to compile the demo using SW4STM32 and the generated .exe file size is 19.1MB.

My question is what alternatives do I have to program the internal and external flash memories. If I use the STlink utility (v3.7), how will I determine where to program the 19.1MB .exe file?

Regards

Edit: Any answer please?

Whats ST-Link V3? V2 is the latest and in STM32F746Disco is V2 included.

Even if available, how you want tto replaced it?

It has the EXTERNAL FLASH loaders for the STM32F746G-DISCO
