Loading MSP430L092 with IAR

Other Parts Discussed in Thread: MSP430L092

Hello,

Simply put, I'm just trying to load some example code onto the MSP430L092 using the MSP-TS430L092 evaluation kit. It should be quite straight forward and yet I haven't been able to get it going. I'm using IAR Embedded, created a new project using the settings given in the fold out pamphlet and have set all the jumpers (JP1 both 1 & 2, JP2 on the active cable PCB as well as JP1, JP2 and JP3 on the target socket) which is all connected to my PC with the MSP-FET430UIF. When I try to download the code to the target board I get:

Clicking 'Yes' then gives me:

The MSP430L092 is in the correct orientation in the socket. LEDs blink three times during initial power up of the FET430UIF so I believe the boost circuit is operating as it should.

Can someone shed some light as to what's going wrong here? I'm by no means an expert in this realm, any help would be greatly appreciated!

Here's a photo of my setup:

Thanks

    Hmmm, I wonder where you're uploading your code to. The L092 doesn't have flash memory. It has a boot rom and fetches its firmware form external EEPROM to ram at startup.
    How did you set-up the IDE? Write directly to ram or write to eeprom? What about the jumper settings? On the target board, JP1 needs to be closed so you can write the EEPROM.

    However, the 'unknown device' seems to indicate that there is a communication problem of some sort. A possible reason is a misconfigured power supply.

    On the cupply board, you'll need to set JP1 and JP2 according to the supply type of the target board. Both jumpers must be closed if you power the target and the cable board from the FET. If you have a separate supply for the target board, open them.
    However, the development guide isn't clear here, as JP1 has two bridges, 1+2. So the description is a bit ambiguous here.

    I had both of JP1's jumpers closed. Your note about JP1-1 needing to be closed to program the EEPROM got me to inspect this further. Turns out there was some grime on the shunt that came with the board that prevented contact. Replacing this shunt  fixed the problem and I'm able to program now.

    Thanks for the help!
