How to display an image stored in external flash on the STM32H7S78-DK using the LTDC controller

Hello,I followed your reference and completed all the steps you mentioned before the screenshots.

 

How to display an image stored in external flash on the STM32H7S78-DK using the LTDC controller 

 

However, I have two issues:

1. Could you please provide a clear, high-resolution screenshot of Tools → Memory Management? The previous screenshot was not clear enough for me to read the settings.
2. I am unable to flash the Appli project onto my STM32H7S78-DK.

 

 

 

This is what I did:

• Initially, I cleaned both the Boot and Appli projects.
• I built only the Boot project and flashed it onto the STM32H7S78-DK successfully.
• Then, I built the Appli project.
• When I try to flash the Appli project, I am unable to flash it onto the board.

 

Could you please explain step by step how I should flash both the Boot and Appli projects on the STM32H7S78-DK?

Could you please provide a clear, high-resolution screenshot of Tools → Memory Management?

Hi ​@Berlin-raj123,

First of all, thank you very much for your feedback.

I have updated the picture to make it clearer and more visible.

I also downloaded the attached project and tested it by following the steps described in the article, the project works successfully.

I think the debug steps may not have been followed correctly. Please make sure the debug settings are properly configured and that the steps described in this article are followed carefully: “STM32CubeIDE: How to debug an STM32H7Rx/Sx project without flashing boot every time”.

Thank you.
