STM32cubeide

[Vignesh_V]

Hi friends,

I am built one custom made PCB with by using STM32F103C8T6 IC for my project purpose.But ,When i am trying to upload my source code by using stm32Cubeide it shows below error.

Error in final launch sequence:

Failed to execute MI command:

target remote localhost:61234

Error message from debugger back end:

localhost:61234: Connection timed out.

Failed to execute MI command:

Error message from debugger back end:

I didn't know how to solve this error .I am tried to solve this error but did not solve the error till now  .so i need your help to solve this error can any one help me to solve my problem?

The usual suspects:

• Check VCC voltage. Note that programmers typically do not supply power.
• Check part orientation. Pin 1 is on the lower left when "STM32" reads from left to right.
• Can you connect in STM32CubeProgrammer? Does it display a voltage?
• Do you have an official ST programmer or a counterfeit one? STM32CubeIDE does not play well with knock-off programmers.

Hello @Vignesh_V ,

Could you please check these points:

• Ensure that the ST-LINK or other debugging interface is properly connected to the STM32F103C8T6 board
• Verify that the power supply to the board is stable and sufficient.
• Update ST-LINK Firmware
• In the debug configuration, Verify that the correct port localhost:61234 and you can change it to 61238

Thanks,

Rim.
