The difference between the S version and AA version of MSP430F1481

Our customer produce switch. He replaced the S version with AA version. The S  worked very well before. There are some problems with AA. It failed to pass the test and can't download the program. So I wonder what difference between them that may cause the problem. How can we fix it?

Tks!

  • The AA version simply is not known to older flashing tools. You'll need to update the tools so they will recognize the processor and can properly upload the code.
    This often too includes updating of the JTAG adapter's firmware.

    There's another thread about the S vs AA in this forum. Please use the search function.

    If you're referring to a different problem, please clarify what's (not) happening. It fails to pass what test? What's the testing environment (Compiler/debugger/flashing software, what programmer/FET etc.)
