MSP430F5152: MSP430F5152 gives Unknown device error while programming

Mahendra Rana

Part Number: MSP430F5152
Other Parts Discussed in Thread: UNIFLASH

Dear All,

I am trying to program MSP430F5152 on my own hardware but it gives Unknown device error on Uniflash tool through MSP-FET430UIF.

In hardware JTAG signal connection is in 2 wire (Spy-Bi-wire) and same as suggested in datasheet.

Even I tried to program after removing C1 2.2nF but still giving same error. Cable length of FRC to program is of 4 to 5 inch only.

Is it MSP-FET430UIF automatically switch from 4 wire to 2 wire Jtag communication or need to do some changes in hardware of MSP-FET430UIF.

Please anyone can help to resolve me this issue.

Hi Rana,

The tool MSP-FET430UIF will automatically loop trying 4-wire and 2-wire, only you need to do is hardware connection between it with F5152. From your description, I suggest you to double check its connection between the UIF tool and the F5152 board, then try again; if still failure, you can change the reset capacitor from 2.2nF to a little smaller one(ie. 2nF)
