problem with msp430f5507 programming - device_unknown message

Other Parts Discussed in Thread: MSP430F5507

Hi everyone,

  I have used the IAR  to download the code to MSP430F5507. The version of the IAR is 5.2. But something was happenning wrong.The IAR was giving the information below.

At first ,I have checked the circuit of  download parts and make sure the IC is correct.

I have tried the solution whose link is "" .I updated msp430.dll and hil.dll  . But it dosen't work.

So,would you please give me some advise?

  • Unknown device means either that the firmware on your FET430UIF doesn’t know the target device, or the communication between FET and target device is broken. Not totally but so far that no proper identification of the target is possible. If using SBW protocol, long wires or parasitic capacitances might be the reason. Or a large time-constant capacitor on RST line. SBW is very sensitive to line capacitance and impedance
