STM32H7B3I-DK, Error message from debugger back end: Load failed


Hi All,

Board : STM32H7B3I-DK

IDE : STM32CubeIDE 10.1

I'm trying to download demo app from STM32CubeIDE.

The demo apps are AudioPlayer and FreeRTOS from "Example Selector".

The building is done, but I'm getting an error as Run.


But I can load en.STM32H7B3I-DK_Demo to use the STM32CubeProgrammer.

How to run some demo app in STM32CubeIDE?

Could the error reporting perhaps be less cryptic and more specific about what actually failed.

B​uild suggest external SDRAM, is that some thing that has an external loader, or debug script?

S​TM32 Cube Programmer supposedly works on same ELF, so exists, is that using an external loader?

Directory name has odd Japanese double bytes.
