JTAG Error connecting to the target: Unknown device

Other Parts Discussed in Thread: MSP430F5438A

Code composer can download the debug with the MSP5438 exp board just fine with the PC.

The EXP board has an M430F5438 part.

I move the JTAG connection to my custom board with the MSP430F5438A part.

USing the o'scope I am seeing activity on all the JTAG pins TDI, TDO, TRST, TCK, TMS...

 

The chip on our customer board is the BGA part marked ”X430F5438A”

We are using Code Composer v3.1 with SR1 and we get the following error when connecting to our board”

MSP430: Error connecting to the target: Unknown device

 

I checked the MSP430 forum website and did not get a direct hit.

Is there any way we can get code composer to output/display low level JTAG communication info?

Is this specific part supported by the v3.1 tools?

    Danimal, 

     

    I am pretty sure that CCS3.1 does not support the MSP430.  You need CCS 4.0 or CCS Essentials 

     

    Are you using the exact same CCS tool chain with the EXP board that works and your target that does not work?

     

    Are you using the same FET tool in both cases?

    You are correct.

    To download to the newer rev. of the part, we need to use CCS4.0

    Yes, we were using the same v3.1 toolchain with the EXP board. 

    Yes, we are using the same FET tool. When we used the 4.0 version of the tools, there was an upgrade request for the FET.

     

    Thanks,
    Dan
