MSP430F2001: MSP430F2001

Part Number: MSP430F2001


Hi

New to this forum....

Have a MSP430F2001 connected as a 2-Wire JTAG Communication (Spy-Bi-Wire)  to a MSP-FET430UIF and using the CCS  Version: 11.2.0.00007.

From CCS get the error :

Error connecting to the target:
Unknown device

The debugger Power LED on and the Mode LED flickers until the error appears then is solid until cancel is pressed.

Have cheked the wiring - all OK

MSP430F2001is know to be good as programmed using windoows XP and Flash programmer.

Running CCS  Version: 11.2.0.00007 on Windows 10 - can see the Debuger in device drivers -

Is their a particular driver which need to be intalled ?

Any recommdations on getting this Debug I/F working ?

Thanks

    Just to add...

    MSP-FET430UIF and using the CCS  Version: 11.2.0.00007  works O/K as a 4 wire connection to a MSP-FET430UIF.

    So is it to do with it been a 2 wire for MSP430F2001 ?

    Hi John,

    I don't think it's a driver issue since you are able to get it to work with 4 wire. 

    How are you powering the device? Does you system match the reference schematic from the MSP430 HW Tools document (shown below)?

    Regards,

    Hi Evan,

    Have checked the wiring as in the sechmatic and it as expected.

    Have tried it with both PCB power and Bebugger power - both are 3v3 and unfortunately both give the same error message.

    Just to note Iam using the simples of program to test this setup - LED blink

    P1.0 on our PCb has a LED connected to ground - so should blink ?

    Thanks

    When using FET power: How much current does your system require. MSPFET can only supply 100mA.

    When using target power: did you connect VCC_TARGET to you systems 3v3 rail?

    Do you have a launchpad? If so, try connecting the MSPFET to the launchpad to see if your FET works with that. More details in MSP Debuggers document:

    Thank Evan,

    Great idea but, unfortunately I don't have a Lauchpad I can use, Also looks like they are all out of stock :(

    Have progresed a bit further but are coming to the conclusion that the MSP-FET430UIF debugger is the route of my problem.

    Using windows XP can connect to the see the device and flash program new code - all OK.

    After this was completed, move over to Windows 10 PC with the MSP-FET430UIF  connected as a 4wire JTAG and external 3v3 power as below:-

    Can see the MSP430 using both the Flash and CCS

    But unfortunatelly as soon as I reprogram the device I can nolonger regain connection to the device.

    Basically believe that the version of MSP-FET430UIF debugger I have is not supported by Windows10 ?

    Is it possible to update the F/W in the MSP-FET430UIF debugger to support windows 10 ?

    Thanks

    Hi John, 

    Can you make sure that the cable is 20cm or less and you have a 1nF (1000pF) cap on the target reset line? Having a longer cable can sometimes cause an issue. 

    Also the MSP-FET430UIF is not really recommended anymore, therefore there may be issues with the fact that you are using a newer CCS. Any chance you can try on older CCS version?

    regards, 

    Henok
