TIDA-010042: What tools and launchpad can i use to program MSP430F5132 MCU?
Part Number: TIDA-010042
Tool/software: Code Composer Studio
I have built the TIDA-010042 however its not setting the MPP of my solar panel to be 17V, instead it is going down to 13V. The battery voltage is 12.5V and charging slightly.
What could be the cause of this? I uploaded the code on the MSP430F5132 using Spy-Bi wire before putting the chip on the board. The programmer used was MSP-EXP430FR2433.
When I try to upload the code on the board again with the chip on the board I get this error. I connected pins 2 and 3 together on header J3 and pins 1, 2, 3, and 4 on header J4 to 3.3V, SBWTCK, SBWTDIO, and GND respectively on my MSP-EXP430FR2433.
I also need to use the GUI. I have downloaded the TIDA-00120 GUI but needed guidance on how to communicate battery voltage to display on the GUI. Pins 4 and 5 on header J1 are connected where and how?
Are you using Photovoltaic Panel or simulate it with power supply??
If the first, than maybe it is too hot or not so sunny and panel power just drops. Then you will have lower voltage. Did you compare result of directly hooked PV ?
Did you try to update programmer on launchpad as suggested in error?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I did try to update it.
In reply to Amar Brar:
I was able to reupload the code. However after doing so when attching my 20V solar panel with a Vmpp of 17.5V, the panel voltage began from 13V and went to 35V after which something burned. Not sure what. When connecting the panel with a Voc of 20V it drops to 0.6V when connected to PV input on the TIDA-010042. Also, when connecting the battery only, it blows a 15A fuse.
Found that transistors Q6 and Q8 were blown and shorting the battery to ground. After replacing them, the MSP is sending gate signals to all the mosfets but is not performing MPPT on my solar panel. The battery is also not charging? How would I verify on the MSP if it is getting the correct panel input power and battery voltage and current?
Need urgent help
Try downloading the latest firmware from TI.com. With the new feature called diode emulation mode, this should prevent increase in panel voltage due to reverse power flow. Also this code was tested by connecting it to a power supply instead of PV
Try using MSP-FET tool for uploading the code. Connections on jumper J4 are as follows:
Pin1(TDO.TDI) of MSP-FET to RST , and pin7(TCK) of MSP-FET to TEST, VCC-TOOL to VCC pin and GND pin of FET tool to GND on board.

I have downloaded the latest firmware and it does not work with a real PV panel. There is nothing wrong with my programmer, can you please test yourself with a PV panel and see for yourself. I would like the software to be fixed.
