CCS/MSP430FR2633: i2c confusion with MSP430FR2633

MSP430FR2633: How to flash the MSP430FR2633 with batch file?

Part Number: MSP430FR2633
Other Parts Discussed in Thread: MSP430F1232, MSP430F149

Hi All,

I have MSP430Flash Emulation Tool. I programmed my MSP430FR2633 with the help of IAR 6.4 version.

I also created the HEX file from IAR  for the production department.

We are trying this command line to download the same hex file on the other MSP430FR2633. 

CLS
MSP430Flasher.exe -n MSP430FR2633 -b -u -e ERASE_ALL -w "FirstButton.HEX" -v -g
pause

We always get the error as "Unknown Device".

We use MSP430Flaser Version 1.3.18.

Please help!!

The same command lines were also used for our other products where we use MSP430F1232 and MSP430F149. Both of these micro works perfectly with same command lines.

    You have the most recent version of the MSP430Flasher so support for this device is there.

    I suspect it may have something to do with your programming setup or design on the PCB.

    Does the board that contains the MSP430FR2633 that is being programmed have a 47k pullup and 1000pF - 2200pF (10nF - 22nF) cap on the MCU Reset Line as shown here in the diagram?

    Are you using 4-wire JTAG or 2-wire Spy-by-wire?

    How long is the programming path from the MSPFET tool to the target (this includes length of wires and traces on pcb)?

    Do you power the target MCU using the JTAG connections or does the target MCU derive power from some other source?

    What is the target MCU VCC voltage during programming?

    I am using 2-wire Spy-by-wire connection. Only TEST, RST, VCC from Tool and GND pins are connected to MSP430FR2633.
    Programming path is may be 3 cm (maximum) from tool to the MSP430FR2633
    We are powering the MSP430FR2633 from the MSP430FET tool.
    We get 3 volt VCC during the programming.

    Also the board contains 47K pull up resistor and 1000pF capacitor on the RST line as mentioned in 2 wire - Spy-by wire diagram as mentioend on TI website.

    Hey i figured out!! TCK pin from Tool side was not connected via 330 Ohm resistor to TEST pin on MSP430FR2633.
    Now the reading back from MSP430FR2633 and writing to the MSP430FR2633 is working fine!!

    Excellent!
    Thanks for letting me know you have it working.
