CCS/MSP430FR2100: Error connecting to the target: Unknown device

For SBW interface (SBWTDIO, SBWTCK, VCC, GND) try lower cap value on RST - GND (1nF insead of 2.2nF). 10uF + 0.1uF is typical combination for DVCC (instead of 2.2nF).

Thank you for the answer. I changed the capacitors and im still getting error:connecting to the target: Unknown device.

Do I need to change the sequence of any pins ?

Hey Arther,

The JTAG and SBW connections are defined in the Hardware Tools users guide, Figures 2-1 and 2-3.  http://www.ti.com/lit/ug/slau278ae/slau278ae.pdf

Overall, your connections look okay.  How are you supplying voltage?  Is it from the board or the tool?  I would check your VCC Tool/VCC Target connections.  

Thanks,

JD

 Hi JD,

I'm supplying the voltage from the board, so I use VCC Target connection (VCC Tool is beeing unconnected).

MSP-FET is starting the debug session, so I assume, it's getting the supply voltage. Unfortunately I still get Error connecting to the target:  Unknown device, when I try to flash the device...

Hey Arthur,

It does seem like the issue is between the JTAG and the MSP430.  

Do you have any boards you can test on?  

Have you tested the connections for conductivity and confirmed the correct orientation of the chip when soldered down?  

Finally, do you have any other boards or EVMS you can test the JTAG programmer on just to absolutely confirm the that programmer is working as expected?  

Thanks,

JD

Hey JD,

I tested my MSP-FET on my oder designs, and it works.

I will be still looking for eventual mistakes in the board layout.

Can you please also take a look on my target configuration file ? I chose there the Processor Family and the MSP430FR2100 Model.
