Hello everyone,
I'm writing this to provide support for my External Loader project for TouchGFX , which I've been working on for a long time.
The External Loader file works good with STM32CubeProgrammer. (Write-Erase-Read operations are possible) LOG OUTPUT IS ATTACHED --> [STM32Cube Programmer LOG Output]
When I run my project file LCD_Driver_v10 and my External Loader file together, I get the following errors: The complete error message is attached. --> [STM32Cube IDE CONSOLE Output]
Error: failed to download Sector[0]
Error: failed to download the File
Encountered Error when opening C:\Users\USER\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.2.300.202508131133\tools\bin\STM32_Programmer_CLI.exe
Error in STM32CubeProgrammer
I also checked this address https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/external-loader-fails-to-download/m-p/136566#M6974 which has a similar problem, but nothing changed.
My Mcu is STM32F743ZGT
STM32CubeIDE verison is v2.0.0
STM32CubeProgrammer version is v2.21.0 (i pasted from cubeide)
Please share with me what I should check first.
Best Regards.
External loader and main project are attached in zip files.
