MSP430 written memery or recognized problem

Other Parts Discussed in Thread: MSP430F1232

Hi eveyone! This weekend,I  started learning programing MSP430F1232  with IAR Embedded Workbench.

The code you used was written by our seniors. it's working successfully when we used our seniors' MSP430 hardware.

However,when we used our new MSP430 hardware made by ourselves ,these mistakes appeared .

IAR can not recongnize my device,and then it was failed to write memory at 0xE000(as picture)

Our device and MSP430F1232 is same as our seniors'. The MSP430F1232 is a new one.

We launched MSP430 by JTAG (MSPFET-UIF).

How could I solve this problem?thank you for the answer .It will help a lot.

PS. the word written on our MSP430 :G4REV F which is different  from seniors' MSP430:G4REV D

       Does this cause any program when you were programing?

    It is possible that your FET simply doesn't know revision F of the MSP1232.
    These MSPs are identified by some pattern which is different for the F revision from the D revision. So if the new pattenr is not in the FETs database, it is nto recognized.
    I fthis is indeed the cause, you'll need an update of the FET firmware.

    However, the 'write failed' message rather indicates that there is some sort of communication problem between FET and MSP. (high capacitances on JTAG pins? supply voltage mismatch?), so that the FET not only cannot properly recognize the MSP, but also cannot properly access it for writing.

    Thank you for your help!!  The problem is same as you said that our FET firmware can not recognize our MSP430.

    As soon as we updated  the version of IAR, we had solve the problem . You helped  a lot .Thanks again !!
