Dear All.

I try to complier sample code from st at D:\STM32\STM32F746NG\

STM32Cube_FW_F7_V1.7.0\Projects\STM32746G-Discovery\Demonstration\

MDK-ARM

On sample video from

https://www.youtube.com/watch?v=R78zvO-s6H0

quality is good.

but on complier and run sample code. quality not same. maybe need to modify some setting in coding.

Have someone can help me to fix this issue.

Isn't the binary of the original demo present somewhere in that package? If yes, try to upload that one, to exclude hardware problem.

Dear waclawek.jan

right now. I check hex file is 15MB.but board limit at 1MB.

#################

In order to program the demonstration you must do the following:

1- Open STM32 ST-Link Utility V3.9, click on 'External Loader' from the bar menu then check

'N25Q128A_STM32F746G-DISCO' box

2- Connect the STM32746G-DISCOVERY board to PC with USB cable through CN14

3- Use 'STM32CubeDemo_STM32746G-DISCO_V1.1.2.hex' file provided under “Binary�? with STM32 ST-Link Utility

to program both internal Flash and external QSPI memory

4- copy the audio and video files provided under 'Utilities/Media/' in the USB key

5- Plug a USB micro A-Male to A-Female cable on CN12 connector

-> The internal Flash and the external QSPI are now programmed and the demonstration is shown on the board.

#################

I make it correct?

Thank you.

The graphical elements are missing from the QSPI memory in your case.

The easier way to upload them is to use

http://www.st.com/content/st_com/en/products/embedded-software/development-tool-software/stsw-link004.html

and to enable the QSPI external loader  (external loader menu -> N25Q128A_STM32F746G-DISCO)

Follow the instructions from the readme file in the root of the demo project

This HEX file also contains the data for the QSPI memory.

This is exactly what you are missing right now.

In order to program it, you must enable the flash loader so STLink utility can program it.

Keil (or any other toolchain...) cannot do that.

Once it is programmed you can use your own compiled version: You can modify it and debug as you like.
