STM32CubeIDE: How to enter commands in the debug configuration as in TrueStudio?

[MB_Inv]

Hello,

I used the following "Target Software Startup Script" in the debug configuration in Atollic TrueStudio (this is necessary since we're using a bootloader and our application binary which I would like to debug is not placed at the beginning of the STM32 flash):

How to enter this in STM32CubeIDE?

I would really need to debug my firmware, but can't figure out how to do the required settings...

Any ideas?

Kind regards,

Markus

When I use e.g.

x Load image

Use project binary

x Load symbols

Use project binary

and under "Run commands":

--

set *0xe000ed08 = 0xC000

set $sp = *(unsigned int*)0xC000

set $pc = *(unsigned int*)0xC004

set *0xE0042004 = (*0xE0042004) | 0x7

tbreak main

continue

---

the binary is flashed correctly to the MCU, but then the (ST-Link V2) debugger connection is lost:

---

Download verified successfully

Error! Failed to read target status

Debugger connection lost.

Shutting down...

---

Any ideas?

Kind regards,

Markus

Is this a new project in STM32CubeIDE or migrated?

Maybe you can consider adding in the scripts line by line and see which one causes your connection to crap out?

Hello,

this is a project from Atollic TrueStudio migrated to STM32CubeIDE.

I will try adding the scripts line by line.

Kind regards,

It seems setting stack pointer and program counter makes problems:

Failed to execute MI command:

set $sp = *(unsigned int*)0xC000

Error message from debugger back end:

Selected thread is running.

Failed to execute MI command:

set $pc = *(unsigned int*)0xC004

Error message from debugger back end:

Selected thread is running.

So my question is how I can make these settings with the STM32CubeIDE dialog.

Kind regards,

Markus

set *0xe000ed08 = 0xC000

set $sp = *(unsigned int*)0xC000

set $pc = *(unsigned int*)0xC004

I have the above 3 commands in my initialization commands and it seems to run fine.

• Can I check that if you don't have any of your initialization commands, your debugger connection is ok?
• If you just put in the above 3 commands only, do you still face the same connection problem?

[MB_Inv]

Hello,

I now put these commands in the "Initialization Commands" field (previously used the "Run commands" field) and now I don't get the error messages any more. So thanks for the hint!

However, now execution is always trapped in "Default_Reset_Handler" and doesn't get out of the loop

for(pulDest = &_sdata; pulDest < &_edata; )

 {

   *(pulDest++) = *(pulSrc++);

 }

Trying to figure out what is missing here...

Kind regards,

Markus

Using the SEGGER J-Link, it works.

For some reason, using the same startup settings, it doesn't work with the ST-Link v2 showing the followin error:

---

Error! Failed to read target status

Debugger connection lost.

Shutting down...

Kind regards,

Your initial posts include some speed settings. I didn't have to do any speed settings for ST-Link to work.

Did you choose the Debug probe to be ST-Link?

[MB_Inv]

My last tests with SEGGER J-Link didn't include the speed settings.

I also tried with the same three initialization commands (yes, I had initially picked the wrong addresses which came from some old debug config setup that I had)

---

set *0xe000ed08 = 0x08020000

set $sp = *(unsigned int*)0x08020000

set $pc = *(unsigned int*)0x08020004

Yes, I selected ST-Link as debug probe:

Try creating a new project and copy over your sources. See if that helps.

[MB_Inv]

Just tried to create a new project in CubeIDE, copied over the sources and adapted the build settings and the linker script. But still, debugging works with J-Link, but not with ST-Link. After downloading the binary, the latter can't read out the target...

Do you have any projects in CubeIDE other than the one you are currently working on that works with ST-Link?

If you have, you could compare and see what is the difference?

If you don't, maybe create a very simple CubeIDE project for your hardware and see if you can program it using ST-Link?
