Communication Error - MSP430-TS430PN80USB

Other Parts Discussed in Thread: MSP430F5529, MSP-TS430PN80USB

Hi,

I'm having the following problem:

 

Communication error.

Check if hardware is connected.

Check if debug protocol (SBW or 4-wire) is correct.

 

This error appears when Download and debug in IAR Embedded Workbench. In CCS v4, the archive msp430f5529.ccxml  has invalid character.

I checked all jumpers and are configured for 4-wire JTAG. Jumpers JP5, JP6, JP7, JP8, JP9, JP10 are connect  to pins 2 and 3. The board is supplied for MSP-FET430UIF. JP3 is connect to pins 1 and 2, and JP4 is not connect. 

 

Regards,

JFK

    Hi JFK,

    First, let me suggest using the example projects provided on the MSP430 website: http://focus.ti.com/docs/prod/folders/print/msp430f5529.html  Look for 'MSP430F5529 USB Sample Kit - Getting Started and Support Files'.  From there you should get a USB CDC project working.  That's a good foundation.

    For your specific IAR issue above, this communication error happens when the IAR communication settings don't match the hardware.  Look in 'Project>Options>FET Debugger'.  Make sure 'Texas Instruments USB-IF' is selected.  Verify that 'Debug Protocol' is set to '4-wire JTAG'.  If that is set correctly, then something isn't good.  You could have a bad USB FET tool, or the chip could be oriented incorrectly in the socket.  Communication with the chip is basic.  No complicated set up is necessary so look for something simple that might have been overlooked.

    Cheers,

    I just connected to my MSP-TS430PN80USB Board using the same jumper settings you have with both IAR and CCSv4.  Few comments to check below.  If not, maybe you do have a HW problem

    >>This error appears when Download and debug in IAR Embedded Workbench.

    I did the same and it connected fine.  Please make sure Project->Options->Debugger is set to FET Debugger, TI USB IF, etc.

    >>In CCS v4, the archive msp430f5529.ccxml  has invalid character.

    I connected here no problem. Using  TI MSP430 USB1 and checkmark MSP430F5529 for .ccxml file,  Not sure why you are getting an invalid character.  Is the driver actually installed (Source tab says drivers\msp430_emu.xml)? Also you might want to drill down in Windows->Preferences->Debugger Options to make sure something is not set the wrong way.

    >>I checked all jumpers and are configured for 4-wire JTAG. Jumpers JP5, JP6, JP7, JP8, JP9, JP10 are connect  to pins 2 and 3. The board is supplied for MSP-FET430UIF. >>JP3 is connect to pins 1 and 2, and JP4 is not connect.

    Only difference is that I have JP2 connected for LED.  And I do have JP4 connected so that I can run the CDC LED demo bus-powered.  When I do this this of course, JP3 is set to EXT.
