Using 2-wire interface from CCS

Hi there,

do have the same problem, wanna program my board with spy-by-wire but it doesn't do!

I can program with JTAG, but not with SBW, CSS always  says "Error connecting to the target: Could not find device (or device not supported)".

I do have a MSP430F5528 (JTAG and SBW supported) and MSP430-UIF.

Already searched all configuration options, is there anywhere a switch to enable SBW?

BTW: With an external programm I can do a blank check and a read memory through SBW, so the connection is correct.

Hi,

I had success in programming a F2232 device using SBW and a MSP-FET430UIF (no special configuration is needed in CCS), however I never tried a F5x device.

Did you check the following references that could help you with your design?

Hope this helps,

 Hi Rafael,

thank you for your quick reply!

I checked already both references, can't find any errors. Now I have soldered down a full JTAG interface loosely to my board and then I can program the MSP430.

But that's quite bad for programming because I can't debug (JTAG lines are used for handshaking a display):

.

So using SBW is my next goal, I need it for debugging, that's terribly complicated now...

Hi,

You may have better luck in the MSP430 Device forums, as they are a lot more knowledgeable about the device itself and may have some other ideas from an electrical standpoint.

My connection was also very "flaky" (wires hanging away from a breadboard) but I was using a different device and therefore other details may be at stake.

Regards,

Rafael

Hi,

obviously all my connections are correct (JTAG is running).

 My question, whether there's a dedicated switch for enabling SBW in CCSv4 was already answered with no.

I'll open a new post in Microcontroller forum, probably there's a problem with the die.

Best regards,

Florian

Olá, Rafael

Tentei realizar a operação de fazer meu fet430uif trabalhar como Spy bi-wire mas não consegui.... o erro que aparece é: Device not found.

Estou usando a launchpad do msp (msp430g2553) + fet430uif, no CCS.

Minhas conexões estão de acordo com http://processors.wiki.ti.com/index.php/JTAG_(MSP430).

Obrigado

Hello, Rafael

i've tried to do the operation of making my fet430uif works in spy bi-wire mode but i could not get it working... the error that debbuger returns me is: Device not found.

i'm using msp's launchpad (msp430g2553) + fet430uif, in CCS.

My connections are just like those in here http://processors.wiki.ti.com/index.php/JTAG_(MSP430).

Thanks

Hello!

Just got it working.

Do this connections

http://processors.wiki.ti.com/index.php/JTAG_(MSP430).

And take care when adding that capacitor... that's were i've made my mistake.

Cheers

Fávero,

Obrigado por reportar o sucesso da conexão. Tive a oportunidade de testar SBW em outras plataformas desde a época da discussão original e não tive muitos problemas. O circuito e o roteamento certamente são detalhes um pouco críticos.

Um detalhe: no futuro por favor faça uma nova postagem e insira a URL da discussão original ao invés de reabrir uma discussão antiga, pois a chance de a sua pergunta passar despercebida é grande.

Saudações,

Rafael
