No ST-LINK detected! Please connect ST-LINK and restart the debug session.

I am using Nucleo F103RB Kit which has onboard St-Link.

I created a simple Led Blink project, and when trying to debug or program the board, I am getting the message that “No ST-Link Detected, and so on”.

But as can be seen from the below screenshot the ST-Link is detected.

But when I used the STM32CubeProgrammer, and programmed the same binary generated by STM32CubeIDE, it works fine, i.e. programming works fine, as can be seen below.

 

I am also learning in parallel the Zephyr, and there also with command `west flash` st-link is able to program the binary but not with STM32CubeIDE, which is very strange.

Apart from this I used the tool from segger to convert the st-link to jlink, and after converting this to jlink, and then selecting jlink in debug configuration of STM32CubeIDE, it works fine.

Can someone please help me that why on-board st-link is not working with STM32CubeIDE?

Summary:

• ST-Link not working with STM32CubeIDE using the latest version 2.1.1
• ST-Link when converted to JLink works fine with the STM32CubeIDE
• ST-Link works fine with STM32CubeProgrammer
• ST-Link works fine with zephyr west flash command also
• I already uninstalled and did a clean install of the STM32CubeIDE, but nothing changed

Just try :

• deselect the fix “st-link SN” .
• connect with : software reset
• select debug mode : openOCD , not ST-GDB

When I selected the OpenOCD, the other two options disappeared, and it is still not working, with same message.

Did you adjust the -> generator options?

 

[xpress_embedo]

Yes, I adjusted and still the same impact.

The strange thing is that when converting st-link to jlink it works fine.

I have another board STM32F429I-DISCO and it is also showing the same behavior with STM32CubeIDE

I use IDE V. 1.18.1 and 1.19 , working fine (on Win and Linux).

So if you dont need the V2.xx , try ...

Hello ​@xpress_embedo 

Could you please try to use the latest version of STM32CubeIDE 2.2.0 and check whether the issue still occurs.

Download STM32CubeIDE2.2.0  from here 

I will be waiting for your feedback.

I don’t know what is the issue, I updated to latest version i.e. 2.2.0 but still same error “No ST Link Detected”.

I remember when I used older version of the IDE in the past everything worked fine.

Did you try unchecking the option for the fixed serial number - as ​@AScha.3 suggested ?

 

Your first screenshot says “ST-Link firmware verification” - so have you tried updating the ST-Link firmware ?
