Flashing code with stlink does not run code

[JKing.8]

I used the STM32CubeIDE to make a simple LED flashing program for an STM32H753. When I run the code with the CubeIDE, it uploads and flashes the LED as intended.

I would like to be able to run this code without the CubeIDE. I am on Mac and have stlink tools installed. I tried running:

st-flash write STM32H753XIHX_FLASH.ld 0x8000000

which outputted:

st-flash 1.7.0

I then tried again with:

st-flash write STM32H753XIHX_RAM.ld 0x8000000 

which outputted:

Both seemed to have valid outputs, but neither make the LED flash. What could I be doing wrong?

Thanks

Are you sure the .ld file is the output of what you've compiled? .ld is usually used for the linker script.

Would Debug/<projectName>.elf be the correct file to flash?

[Pavel A.]

This software is not from ST. It is an opensource project. For help you can ask the authors and maintainers.

From this documentation, it accepts only bin files, not elf.

No idea what stm32cube does - never used it, but openocd does not run a program after flashing. You need to execute reset command manually or add to programming sequence.

I highly recommend openocd for ST-LINK. Recently they added STM32G/C support.

Works just perfectly under FreeBSD. and for sure almost any other commonly used unix systems.

Why dont you use cube programmer?

[WojtekP1]

Because there are still people in the world that:

• don't want to use point and click way of "work"
• don't want vendor lock in
• don't want binary only packages
• want unix style tools that can be easily integrated with everything
• want small and simple tools doing one thing well, according to unix philosophy
• want tools that they can fully understand.
• want tools that never limit you.

I have the issue here, did you find a solution to your problem?

Better is open new and explain...
