BSLDEMO2 Error 'Synchronization Failed'

Other Parts Discussed in Thread: MSP430F2112, MSP430G2553, MSP430G2231

Hello,

When I try to download a code to MSP430 using USB-RS232 cable on BSLDEMO2 program, it gives me 'Synchronization Failed!' Error.

Currently I am using USB-RS232 connection but I also tried RS232-RS232 connection and it gives same error.


Does it have to do anything with baud rate? if so, how do I setup/change baud rate.

Please help. Thanks in advance.

Regards,

Akash

    You are not very specific about your circumstances.

    Which MSP430 are you talking about?

    Which USB-RS232 (or RS232-RS232) cable did you use?

    None of the MSP430 can be connected to none of the USB-RS232 (or RS232-RS232) cable directly. What did you do?

    The error message you got is not specific either (not your fault, but you work for TI and I do not). It simply means that program did not work. If you do not use any cable and you do not have any MSP430, you probably will get the same error.

    Here is more information, sorry if I wasnt clear before.

    I am using MSP430F2112. And, I used USB to straight serial adapter RS232 cable.

    I have a system (projector) which has RS232 connection, so instead of programming MSP430F2112 by using emulator board, I would prefer to use RS232 so I dont have to open the projector every time.

    Previously on this thread, someone recommended to use BSLDEMO.exe tool, and thats what gives me 'Synchronization Error' when I try to download a file to MSP430 using RS232. I can use the same file to download via emulator board correctly.

    Hopefully this will provide you better input to answer question.

    Hi Akash, I have a similar problem. I am using the LaunchPad with MSP430G2231 on it and my target has an MSP430G2553 on it.

    I have made the connections as suggested in SLAA535A.  I have programmed the BSL on to the MSP430G2231 on the Launchpad.

    Then i connected the Target to the launchpad and reconnected the USB. The Red LED and the GREEN LED are on indicating that

    the Target is in BSL mode. I have verified that the USB is using COM1 on the PC.

     However, when I run BSLDEMO2 with the command line BSLDEMO2.exe -cCOM1 -m1 +epvrw NewGLDTIV3_2.txt PAUSE

    the program starts up and I get the error -  Synchronization failed!

    I have tried many other scripts, but, same problem.

    Any suggestions from anybody would be welcome since TI is not of much help with such problems.

    Now I have started playing around with the BSL program itself.  Difficult to debug because the PC Tx and Rx are shared with MSP-Tx and MSP-Rx. on target.

    HELLO,

    I THINK BSLDEMO2.EXE IS BASED-MSP430. IT IS USED GENERALLY FOR USB CHIP OR RS232. YOUR HARDWARE IS NOT COMPATIBLE WITH THIS SOURCE CODE.

    YOU SHOULD MODIFY THE WAY WHICH GET SEQUENCE ENTRY BSL.
