Connection problem

Hello,

I'm using CrossStudio for MSP430 Release 2.0.9.2010033104.7366.

After replacing target (to an identical card with same version of firmware), I get the following error when I try to connect: "Can't identify target device. No error".

I connect through JTAG MSP-FET430UIF.

What could get wrong? How do I fix this?

Thanks!
