Hi,

Please if somebody got the same problem and how did he/she solved it. Please help me here

You sure the connection is ok?

Did you see this note:
"Do not launch more than ONE JTAG-connection at the same time! So after something went wrong, first close all open connections and try again"

I was able to get a connection but wasn't able to debug. I got another error.

As you wrote in the other thread, you have the problem on the AscTec Mastermind with (I think) Ubuntu 12.04 running on it.

I recommend to read this: http://wiki.asctec.de/xwiki/bin/view/AscTec+Development+Tools/SDK+Setup+for+Linux

Maybe this could help you. It explains the configuration of the AscTec SDK on a Linux (Ubuntu) system.

I still have an error when doing the third step of the HL flashing task: 'Launching AscTec JTAG Debug' has encountered a problem.

Try this

Run -> Debug Configurations -> Debugger
GDB debugger : (add the path of the file "arm-elf-gdb")

Windows : GDB debugger : arm-elf-gdb.exe
               change it to : C:\AscTec_ARM_SDK\WinARM\utils\insight\bin\arm-elf-gdb.exe (for exemple)

Linux : GDB debugger : arm-elf-gdb
          change it to : C:\AscTec_ARM_SDK\WinARM\utils\insight\bin\arm-elf-gdb (for exemple)

It works in my case using Windows 8.
