Fatal error: Failed to re-initialize Session aborted!

Other Parts Discussed in Thread: Z-STACK, MSP430F5438

Hi,

I'm new to z-stack programming. I have encountered above error when i tried to "download and debug".

Sat Mar 29, 2014 12:05:57: Could not find MSP-FET430UIF on specified COM port : (Initialize) , port=USB, version=0xffffffff
Sat Mar 29, 2014 12:05:59: Fatal error: Failed to re-initialize Session aborted!


Im trying to run the Temperature Voltage  Sensor Application sample; I have 2 TI boards, I wanna use one as a coordinator and the other as a end device.

I was able to burn ZNP to the boards and when I tried downloading the application to the board I have encountered above errors.

When I select simulator for debugging the above example runs fine.

Im using IAR 8051 and IAR MS430- editors.

Please help!

 

 

 

  • The error message tells you that the debugger cannot locate the FET on USB.
    Either you don’t have your FET430UIF (or in case of an ez430 LaunchPad, the board) connected, or the drivers loaded for the FET are incompatible with the MSP430 lib used by the debugger (VCOM vs. CDC driver model). In any case, it has nothing to do with z-stack. It’s a generic communication problem between the debugger and the JTAG interface (FET) it uses for programming the target.

  • Sirs:

           Having a heck of a problem debugging with IAR.  In the device manager, the MSP430 Uart interface is present and claimed to be working.  However I do not see the MPS430FET debugger driver and have tried to install the drivers by executing the driver .exe in program files IAR/ 430/xp.

         My XP tries to load the launch pad but fails with " Emulator ... Failed to re-initialize  Session Aborted  "

    Have scoped the signals and do see signals on rst and test with the xp machine.  My vista machine which has worked in the past produces no signals at all on rst and test.

    Any suggestions?

    Thanks,

    John

  • Hi,

    I had read all answer for this problem. However I could't solved this problem. I am using MSP430F5438 integrated and IAR Embedded Workbench 6.30 programming. How could I locate the FAT on USB ? I haven't done it.

    Please help me ! ! !
