MSP430G2553 cannot program

Other Parts Discussed in Thread: MSP430G2553

Hello All,

I am trying to program a custom board which has an msp430g2553. I am using CCS Version: 4.2.4.00033, windows 7, x86 OS.

The problem I am having is, I cannot load the program to the msp430g2553.

I am using SPY by wire to load the code.

This is what happens when I try to debug.

    There's a communication problem of some sort. maybe too much capacitance on the RST pin, or not enough supply voltage (during programming, a higher voltage is required than for operation, also the current consumption has peaks of some mA)

    Hi,

    I'm trying to program a custom board too. I have MSP430G2553 in 28 pin version. If I connect it with TI LaunchPad (rev.1.4), it shows "Device not connected or supported". I'm using CCS 5.3.0. Can be the problem I have 47k resistor and 10nF capacitor on RST pin?

    Thank you for your answers!

    MSP430G2553 is not supported by Launchpad v1.4. You must update Launchpad firmware.

    http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_Firmware_Update

    MSP430G2553 have same flash parameters like any other MSP430F2xx device, and my programmer don't have any problem with MSP430G253

    Thank you for your answer, I'll try it. If I'll have any problems with comunication between LaunchPad and MSP430, can I write to you?

    Btw., aren't you from Czech Republic?

    I updated my LaunchPad firmware, but still doesn't work. For test I tried to load few lines. I enclose a screenshot. Any ideas how to solve this problem?

    Hi Dalibor,

    Dalibor Sisak said:

    Yes. For SBW, the capacitor on RST must not exceed 2.2nF. Please see the hardware tool's user's guide diagrams in section 2: www.ti.com/lit/pdf/slau278

    For a quick test you could try simply removing the cap and see if you can now program. If you still have issues, it is a good idea to post the section of your schematic that shows your programming connections.

    Regards,

    Katie

    I tried to find and solve software problems, but forgot fix this. Thank you very much Katie, it finally works. :)

    I had the same problem, and removing the capacitor in RST solve my problem. Thanks! i will change it for a lower capacitor.
