Fatal error: Could not find device (or device not supported) with MSP-TS430PZ100C

I am using MSP-TS430PZ100C target board with MSP-FET debugger and IAR version 6.10.1.
When I try to run an "Flash LED code" example code provided by IAR, in debug mode I get the following error.

Firmware version 30400020
Interface dll version 3.4.0.20
Unknown device : (OpenDevice) , Device=MSP430F6438, PwLength=0x0
Fatal error: Could not find device (or device not supported) Session aborted!
Internal error : (SetEEMSequencer)
Fatal error: Closing debug session Session aborted!


I have checked all the jumper settings, also Vcc is supplied internally correctly (Verified by probing Vcc and pin 11 of the controller)
What could be the possible cause of this error?

The chip used is MSP430F6438 with the following IAR settings:
Device description file used : MSP430F6438.ddf
Debugger: FET debugger with Texas Instrument USB-IF connection

    Hi,

    this should usually work out of the box, and most of the time it is simple mistake such as wrong orientation of JTAG connectors, chip placement on the board, etc. Have you tried to look in the forum for similar problems?

    Thanks fo quick reply,

    You are right it was pin orientation.

    Apparently the evaluation board we have has incorrect  pin 1 marking for the microcontroller chip.

    after looking closely we found a mismatch in the header pin 1 marking and PCB silk screen marking :-X

    Regards,

    Suman

    The socked used for the original design did not have any marking. But then the manufacturer of the socket was changed (or the manufacturer decided to put a marking on it) and the marking on the socket was not where PIN1 should be.
    I fell into this trap too when inserting my first MSP430F5438 into its demo board.

    Luckily, the MSPs are tough guys and can bear such an accident without permanent damage. At least in most cases.
