Need to keep reloading TouchGFX application on STM32H757I-EVAL; doesn't run after power on.

[Shiv09]

Hello All,

 

I am using the STM32H757I-EVAL for one of the development project for Touchgfx,

1) When-ever I am loading/debugging the project using STMCUBEIDE, only in System Mode I am able to detect the Board, but not in Flash mode.

2) With STMCubeProgrammer, I have to connect the device in System Mode, then I have to Erase the Internal and External Flash, then disconnect the Board and Bring the Device in Flash Mode and then Flash the code. Till now I am able to run the Program,

But as soon as I disconnect the usb (stlink), The Previously loaded program supposed to run as the mode is still in flash, but I can see anything on screen. 

Could anyone please let me know the correct way to do it ?

I mean I don't have to load or flash code again and again to test. The program should load from Flash after power ON- OFF-ON. 

Just for info 34757228 is the size of the program.

Hello,

What do you mean by System mode and Flash mode? do you mean bootloader and user flash?

Hello @mƎALLEm ,

 

I mean the switch provided for STM32H757I-EVAL, as in this image.

 

Suppose if I want to load the firmware in Flash so that every time the device is power on, the older loaded program should retain and shall run.

 

Now every time I make the device on the program doesn't run, I have to load it again and again.

If there are some settings or configuration to do, then please let me know.

 

Please feel free to ask if you need something additional.

Sorry the issue is not quite clear.

Which program are you uploading to the board?

What method are you using to upload the program to the board? STLINK, bootloader? if over the bootloader what steps are you following?

On which position you keep that switch for each step before, during and after programming?

Do you face the same issue with another program?

Hello @mƎALLEm ,

 

No the issue is still live, tried different option but didn't worked. Currently loading the changes on board and testing it.
