Other Parts Discussed in Thread: MSP430F47197

I use MSP430F47197 and load a program by MSP-FET430UIF. The red LED start to blink during the program loaded but after stays on. Is there anything wrong with FET or the board?

    Hi CaEngineer,

    Don't worry about that. You just completed download program to the microprocessor and stayed in "Debug" mode. The CCS is waiting you to press "Resume"(or F8) to run the program. So everything is fine.

    Hi Sunglin!

    I don't use Code Composer Studio, I use IAR Benchmark. In IAr we need to press F5 but after F5 even the break point is still in Disassembly area and the red LED is stay on!

    Hi CaEngineer,

    I think it's not a problem with the Programmer or IAR IDE. The red led will turn off when you terminate the debugging mode. You should try it yourself, because I use CCS not IAR.  Hope this could be helpful to you.

    Well, they are pretty much the same as I found out when I used to use CCS. But it is kind of weirdo stuff to me when I had another board and code and I could see the red LED gets off when the program is loaded!

     Hi CA, is the board where you loaded code working? Is Reset logic working and not stuck at low level?

     If another board work fine try inspect the suspect one, first measure if reset work properly, if not may be it reenter debug mode forever. Is your software ready? watchdog is disabled or correctly served?

    Hi Roberto,

    No! This is the point that has made me doubtful about either board or the FET Emulator!

    I am not sure about my code either and even for a simple code it stays Red!

    No, when for the first time it goes to "watchdog reset" I press F5 and it jumps to Disassmbler and Greenlined over! Actually I should Print Screen that message next time as I cannot access to the board now!

    Actually the board on which we worked, it is gone! (burnt already! :( )

    I use IAR Benchmark and yes I have disabled the watchdog.
