MSP430F2618: Error connecting to the target: Unknown device

Nicholas Luong

Part Number: MSP430F2618
Other Parts Discussed in Thread: MSP-TS430PM64A, MSP-FET, MSP430F4152

Hello,

I am using the MSP430F2618 with the MSP-TS430PM64A dev board and MSP-FET. When I attempt to program the part, it gives the error: "MSP430: Error connecting to the target: Unknown device"

I know the dev board jumpers are properly configured because I am able to program the MSP430F4152 (pictured on the right). Can you please verify the part marking in the picture attached?

Not working part on the left, working part on the right. What is the significance of the first line and 3rd line on the parts?

If the part marking looks ok, what could be the cause of the error?

Thanks.

The issue is resolved. The MSP430F4152 worked in SBW mode, but the MSP430F2618 did not. Using JTAG was the solution.

I'm still curious to know about the 1st and 3rd line on the device marking, if someone has the answer though.

Thanks.

In case you haven't seen it, the Package Markings section of the following errata documents linked from the product pages explains the device marking:
