MSP430 "processor reset failed: could not find device (or device not supported)"

Hi,

I'm trying to debug TI MSP430F449 with CrossStudio 2.0.9 through TI USB JTAG MSP-FET430UIF. I've successfully connected to the device, but when I try to download to it or resetting it or anything else, I get the error "processor reset failed: could not find device (or device not supported)".

I got this project (including all its configurations) from CrossStudion 1.0.3 and the project definitely worked, including fully functional debugging.

Please help.

Thanks.

  Was the board powered by the FET430UIF when using CrossStudio 1.0.3?

  I'm not sure that the previous developer used the FET430UIF. Anyway, the board has its own battery, but in project's settings a 3.3V power is set.

  Try setting the vcc target property to be zero and see what happens.

  Tried it, without any success - the same error appears.

  Do you have another board you can try?

  Unfortunately, no.

  Are you using "start debugging"?

  After connecting, I've tried several options:

  Target -> Attach debugger, reset, download %project%

  Debugger -> Go

  I'd try

  Target | Connect

  Project | Start Debugging

  Getting the same error.

  Tried to cancel the Watchdog with the relevant jumper - didn't help.

  I thought the MPS430 watchdog was software thing? Does your board have some external reset logic?

  It's hardware thing also - the board has a jumper for canceling the watchdog. It also has a jumper for resetting itself. I've tried it of course.

  A parallel question: in the output map file there's no mention for the heap and the stack positions. Neither is it mentioned in the MSP430F449.xml file.

  Where can I find the positions of the stack and the heap?

  Is the reset pin on the JTAG header connected to the reset logic of the board?

  There isn't a stack as such. The startup code sets the stack pointer to the top of RAM.

  Use the symbols browser to see where things are.

  Update from the field:

  it works again! I've canceled the watchdog with the jumper and clicked Target->download %project%. It finished the downloading and verifying and the program runs on the board.

  But when I try to debug it gets me to the same error: the studio tries to download, gets stuck at the middle and returns "download failed" error. Afterward, the previous error appears.

  I want to do hardware debug (ROM, Flash) without downloading my code to the board. How can I do this? Each debug option that I choose starts the "download" phase.

  Sorry, didn't mentioned that before downloading the project with canceled watchdog, I've also canceled the 3.3V power supply in the project, so it works from the board's battery only.

  Not sure if this is too obvious to mention, but there is a slightly different connection required for the FET dependant on wether the board is powered from the FET or if it powered from its own supply. I use an arrangement with a jumper to swap the connections, and have seen some strange results if the jumper is in the wrong position

  The debug toolbar has an "Attach" that should avoid the reset and download.

  Well. I've other questions, but they are not related to this thread.

  So I guess the thread can be closed. I've succeeded downloading the software to the board after canceling the watchdog and canceling the power supply through JTAG, leaving the board with its own power supply.

  Thanks for the help!
