MSP430FR2355: MSP430FR2355 , trying to program it with SPY-BiWire through an MSP430FET, Get Fatal Error: Could not find device (or device not supported)

Hi,

I developed my code using the Launchpad (I had placed sockets on the target board and plugged the Launchpad into it).

Now I soldered the MSP430FR2355 onto my target board (the target board is the board that I designed that has my application circuitry, along with the MSP430 on it).

I have an MSP-FET programmer that I just bought and plugged the flat ribbon cable into a 14 pin socket on my target board.

In IAR Embedded Webench, I then selected Projects > Options > FET Debugger > Debug Protocol > Manual Selection > Spy-Bi-Wire.

I had used the same IAR just yesterday to develop my board on the target board, but with the Launchpad connected to my target board.

When I hit the "Download and Debug" icon (right-pointing triangle in a green background) I get the error message shown in the title block above:

"Fatal Error: Could not find device (or device not supported).

Any idea what step I have left out?

Also, I put the scope probe on the SBWTCK pin on the JTAG 14 pin connector on my board and do not see any activity on that pin when I hit the "Download and Debug" icon.

Hello Kenneth,

If you are trying to use Spy-Bi-Wire, be sure that you have the correct connections. Figure 2-3 in the users guide below shows the correct wiring.

If you have the full 4 wire JTAG connection as shown in figure 2-1, you probably just need to select 4 wire JTAG in IAR.

If you are using the MSP-TS430PT48 target board, you can also find the schematic in the users guide above, figure B-36.

HI , I pasted my schematic here. Is the 330 Ohm resistor (R4) necessary between the JTAG connector pin 7 and 8?

Problem solved. The JTAG 14 pin connector on my target board was pinned out incorrectly. To fix this, I inserted the MSPFET flat ribbon cable backwards and now it works.

Ken,

No, the 330 ohm resistor is not required for the MSP430FR2355. Your schematic seems to be based on figure 2-2 in the users guide, which is to be used for MSP430F2xx, MSP430G2xx, and MSP430Fxx devices. Your MSP430FR2355 would need to use the diagram shown in figure 2-3(no 330ohm resistor and pin 8 disconnected from JTAG header).
