Debugging STM32F103C8T6 using the debugger of STM32F446RE nucleo board.

[Shaku]

Hii everyone,

I want to debug STM32F103C8T6 controller by using the debugger present in the STM32F446RE nucleo board. After setting the parameters , when i go for debugging the following error is coming. Please guide me how i could debug my respective code using the STM32F103C8T6 controller.

Output

Device connect error

Error in initializing ST-LINK device.

Reason: Failed to connect to device. Please check power and cabling to target.

Thank You...

Hello @Shaku ,

Make sure to upgrade ST-Link firmware.

Check the debug pins connections and GPIO pin used for toggling.

Thank you !!!!

After checking the debug pins and GPIO pin i am getting the same error. I'm also upgrading the ST-Link firmaware but the error is coming continuously.

Have you set all the links on the Nucleo board correctly - to disconnect the STM32F446RE Target from the ST-Link?

Post a schematic of your connections.

Post some good, clear photos of your setup.

That means the computer isn't even connecting to the ST-Link.

Does it show up in the Device Manager (or equivalent)?

If not, check your cable: are you sure it's a full data cable - not jus a charging cable?

Try other cables.

Try other USB ports.

Thank you!!!

I am using it in Linux(ubuntu) OS.

this is the circuit connection of STM32F103C8T6 with STM32F446RE nucleo board debugger.
