Error: failed to download Segment[0]

[CBurk.2]

So I have a STM32F769I-DISC0 board, and I am trying to write a binary file to it. Originally I was trying to write a binary file that was generated by the touchGFX Designer tool, but now I am simply trying to get the touchGFX example program for this board deployed on the board. This code compiles fine and generates binary/hex files, it just wont flash to the board for some reason. This is the full message I get on the STM32CubeIDE:

I also tried to flash the board using the STM32CubeProgrammer, but got the same results, the logs for that are below:

The other two posts I could find on this didn't address the issue:

Any help would be much appreciated, and let me know if you need more information - thanks

Hello CBurk.2,

Did you select the external loader for the STM32F769I-DISC0 board before trying to download the code ? Or are you only using internal memory for this application ?

[mattias norlander]

Which exact example application are you refering to? Is it this one?

STM32Cube_FW_F7_V1.16.1\Projects\STM32F769I-Discovery\Demonstrations\TouchGFX\SW4STM32

How is the project linked? Have a look at the Build Analyzer view in CubeIDE to examine the build output to see if it is linked towards internal or external flash.

If it does not work in STM32CubeProg stand-alone, then it cannot work in CubeIDE.
