Programming CC430F5135

Other Parts Discussed in Thread: CC430F5135, MSP430F1612

I have a couple of questions regarding programming the CC430F5135:

1. When using the MSP430 Flasher command line utility and the MSP-FET430UIF I get the error:

Accessing Device...

Exit: 16

ERROR: Unknown Device

I believe the device is connected and powered properly. I can use Elpotronic's FET-Pro430 programming tool, and it works fine. The programmer also works fine when using it as a debugging through Code Composer Studio. This error only occurs when using the command line utility. I'm using the Spy-Bi-Wire interface. I have the latest version of MSP430 Flasher (v1.2.1). I've tried several versions of FW on the MSP-FET430UIF, and none of them work.

2. How long should it take to erase, program, and verify a 16K CC430? It currently takes around 30 seconds using the Elpotronic tool with MSP-FET430UIF. Is the GANG programmer faster? Is the 4-wire interface significantly faster than the 2-wire interface? Are there any other options that will program faster?

Thanks,

Chad C.

    Just a quick update:

    1. For no particular reason, the MSP flasher started working. I removed my 2.2nF capacitor on the nRST/SBWTDIO line, and the board programmed; then I put the capacitor back and it still programs. I have no explanation there

    2. I see that Elpotronic sells a FlashPro430 that they claim is faster (http://www.elprotronic.com/flashpro430.html). They claim it can erase, program, and verify 32KB via spy-bi-wire in 5.7 seconds. Does anyone have experience with this programmer?

    Maybe you just were at the edge between wroking/not working and you soldering changed the capacitance a bit.

    No, but it is no wonder.

    The MSP430 JTAG (4 wire) can take 6MHz, SBW even more. However, the FETS use an MSP430F1612, whose maximum CPU clock is 8MHz. So it cannot use full JTAG speed and even less run maximum SBW speed.

    However, if the Elprotronic device uses higher freuency, teh line capacitance plays an even bigger role. But if the code is smart (and I know they are smart guys), it checks what is the maximum and reduces speed as necessary.
