CCS/MSP430F2350: msp430f2350

Part Number: MSP430F2350
Other Parts Discussed in Thread: MSP-FET

Tool/software: Code Composer Studio

Design is a small msp430f2350 design running at 2,4 volts.

Am using CCS version 8.2 and an msp-fet as an emulator. Things were working well but have crashed. Code gets lost (SP out of range or starts executing the BSL or whatever). An’t find how to set the power to mst-fet to the lower voltage (how do you do that??) and I hv4e noij iea how to track this problem down.

 

So two questions:

  1. How do I change the power to the target on the msp-fet?
  2. How do I find out what is going on this this design and code?

 

All Help will be greatly appreciated!!

  • 1) I haven't used the MSP-FET in a while, but with a Launchpad I have a text box at "[Debug Perspective]->Tools->On-Chip Flash->Target Voltage [mV]" which is settable.

    2) You haven't given us much in the way of clues. You can try stepping through the code to see how far it does get before it fails. If your code is fairly small, you can post it here and maybe someone will see something.

    [Edit: For (1), I see a similar box at "Project->Properties->Debug->MSP430 Flash Settings"]

    [Edit: What CPU (MCLK) speed are you using? Your description sounds superficially like the effects of running too fast for your supply voltage [Ref Data Sheet (SLAS518E) Fig. 1].]

  • Hi Bob,

    which IDE are you using for code generation and programming?

    When a device runs out of control I always recommend if you operate it according spec means are clock the CPU slow enough for 2.4V supply?

    Other questions is if you do not generate STACK overflows in way you write into your RAM variable space?

  • Hi Bob,

    any feedback on the questions above? If there is anything we can do for your please let us know otherwise I will close this thread by end of the week due to inactivity.
