Is it possible to install the M4 firmware only with stlink line with STM32CubeIDE?

[MJo.3]

Hi

I'm testing the firmware code using STM32MP157D-DK board.

The current configuration for testing use st-link CN11 and ethernet to upload firmware program by using STM32CubeIDE.

My question is, Is it possible to do the simmiar firmware program uploading only with st-link CN11 connection?

Thanks

Hi @MJo.3​ ,

Yes it's what we call "engineering mode" where you can debug/tune the M4 firmware in an "MCU like" way

refer to STM32CubeMP1 development guidelines - stm32mpu

Change boot switch of your board :

STM32MP157x-DKx - hardware description - stm32mpu

And see the option in CubIDE debug configuration.

Hope it help

Hi!

Thanks for fast response.

I make the device that use both M4 and A7 chip and it's covered by a plastic cover.

After the firmware code pass the test, It will be installed in M4 chip and the plastic cover will cover the chip.

I will make a stlink port on cover if I can upload the code only with it.

But currently, using ethernet and stlink both is Only way I know.

The solution you gave me isn't fit my situation because That need the switching the switch on the board. So, Is there any way that debug/upload the M4 firmware code only with stlink line when the whole program uses the A7,M4 both and not touching a board at all?

Thanks.

Hi @MJo.3​ ,

Ok so you always target Production mode with Linux on A7.

In that case you can't "load" the firmware with CubeIDE/ST-Link but just attach on it and debug.

You need to have a way to provide the firmware in Linux file system and send a command to start the firmware.

CubeIDE use ethernet connection to do it.

What's your constraint regarding the today way of working ?
