I have to use MSP430i2030 for a project and I tried burning code on it using MSP430G2553 launchpad. I tried burning a simple code on toggling the LED, however, the CCS complained that it could not find the chip, yet I could see the LED being toggled. But no matter what changes I make to the code, it keeps on toggling (even when i commented that part of the code). Below is the way in which I connected my chip to the launchpad.

Can anyone please suggest an appropriate way to connect the chip to the launchpad? How do I setup the interface correctly? enter image description here

Also, as per Texas Instruments, this chip cannot be used with the launchpad, however, I have gone through some examples where people are able to use the unsupported micro-controllers as well.

  • \$\begingroup\$ Could you suggest any other way apart from using MSP-TS430RHB32A(as per TI). \$\endgroup\$ – user3602066 Jul 20 '16 at 15:26

    \$\begingroup\$ Without a schematic or a better picture, it's hard to tell exactly how your chip is hooked up, but if my interpretation is correct, your MSP430 has no ground connection. \$\endgroup\$ – Cheibriados Jul 20 '16 at 15:36
  • \$\begingroup\$ yes, in the current image it is not connected to ground, however, I did connect the relevant pin (AVss) to ground, yet I am getting the same error. \$\endgroup\$ – user3602066 Jul 20 '16 at 15:39
  • \$\begingroup\$ Try adding a 47k pullup to the RST line as specced by TI and see if that makes a difference. \$\endgroup\$ – Cheibriados Jul 20 '16 at 15:54

After repeated attempts to communicate with the chip using launchpad, I can finally say that it is not possible to use launchpad for programming MSP430i2030.
