Debugging problem of STM8

Question asked by arun.arun on Apr 30, 2015
I'm doing a project on STM8S003F3. Im using IAR instead of stvd for developmeant purpose. I could create my sample project and successfully debugged it. It was working fine for few days. But today debug session terminated in the middle of debugging(an error shown saying location cant be accessed). After that, an error is shown whenever i try to download the code. The shown error is "Failed to set configuration with MCU name STM8S003F3: SWIM error[30004]: comm timeout"
Everything was working fine before and i didn't change anything. I upgraded the firmware ST LINK but it didn't help to solve the error.

How can i solve this issue?
