Hi,
What DRV boosterpack is being used with the LAUNCHXL-F28069M? Were JP1 and JP2 jumpers removed on the LaunchPad to isolate the emulation and controller power supplies / GNDs?
Best,

BOOSTXL-DRV8301 REVB motor drive Booster pack was used.
Only jumper JP6 was removed.All other jumpers were connected.
The boot switch position was UP-UP-UP
Hi,
They should follow the BOOSTXL-DRV8301 hardware guide instructions (https://www.ti.com/lit/slvu974). See below about removing 3.3V jumper between emulation and controller side. If they don't remove this then there will be contention between the different 3.3V power supplies.
The boot switch position was UP-UP-UP
I think the switch should be DOWN-UP-UP for emulation connection. Also may need to change UART jumpers based on BOOSTXL-DRV8301 hardware guide.

One clarification in the user guide it is mentioned to keep S1 in ON ON ON Position.
Also It would be helpful if you could tell what is the correct process to connect oscilloscope to view values of Va,Vb and Vc and also which are the parameter we need to look in Code composer studio to get the phase voltages and currents
Hi,
One clarification in the user guide it is mentioned to keep S1 in ON ON ON Position.
This is fine, I think just S1 switch 3 needs to be ON (TRST pin) for emulator to connect actually. What user guide is this from? I was referring to BOOSTXL-DRV8301 guide, but don't see the shared info in it.
Also It would be helpful if you could tell what is the correct process to connect oscilloscope to view values of Va,Vb and Vc and also which are the parameter we need to look in Code composer studio to get the phase voltages and currents
I think this guide should have the details on what the user should probe and see on an oscilloscope, https://www.ti.com/lit/spruhj1.

The snap I took is from the Read Me FirstInstaSPIN-FOC and InstaSPIN-MOTION LaunchPad and BoosterPack document.
Thanks for sharing the document.Will I also be able to find which parameters in Code Composer Studio to look out for the phase voltages and currents
Did you try follow the user's guide of LAUNCHXL-F28069M to run a lab or an example project without connecting the BOOSTXL-DRV830? Any issues when run an example with the LAUNCHXL-F28069M standalone?
Yes I have tried and run the temperature sensor example(both demo and example code ) and Blinking of LED example without connecting DRV8301 and I was able to run without any issues.
OK. Follow the hardware guides of LAUNCHXL-F28069M and BOOSTXL-DRV8301 to connect the BOOSTXL-DRV8301 on the right side correctly, make sure that REMOVE LAUNCHPAD 3.3V JUMPER (JP1 and JP2).
1. Run the LAUNCHXL-F28069M standalone within CCS to erase the code in the device, or load an example InstaSPIN-FOC lab.
2. Connect a DC power supply (< 25V) to the BOOSTXL-DRV8301.
3. Power on the BOOSTXL-DRV8301 first to see if the output current of the DC power supply is right. If the current is high that means
4. Connect the USB cable to the LAUNCHXL-F28069M, connect the right low voltage motor to the BOOSTXL-DRV8301.
5. Build and load the right labs to LAUNCHXL-F28069M, you may try to run the labs from lab01, and then lab01b... if you didn't work on the InstaSPIN labs for motor control before.
Thank you so much for the step by step explanation
Is it possible in any way I can be able to use the existing board(the one which is getting heated)?
Current state of my launchpad without connecting to booster pack(In standalone)
CASE 1:
Jumpers connected JP1,JP2,JP3,JP4,JP5 and JP7
Led D9 keeps on glowing and microcontroller is getting heated
CASE 2:
When either JP1 or JP2 removed Led D4 glowing and microcontroller not getting heated.
But in both cases test connection in target configuration file is getting failed.
Please advice if something can be done to make the launchpad work.

What do you mean? Which board is getting heated?
Is the LAUNCHXL-F28069M getting heated without connecting the BOOSTXL-DRV8301? if so, why did you mean below?
Yes I have tried and run the temperature sensor example(both demo and example code ) and Blinking of LED example without connecting DRV8301 and I was able to run without any issues.
I understood your question as whether it was working in standalone mode before the heating issue had happened and hence replied it as working
But as i have mentioned in the document after that heating had happened Launch pad with and without booster pack when connected with USB only LED D9 is glowing and heating of microcontroller is happening.
Sorry for the confusion
Seems like the LAUNCHXL-F28069M was damaged. As kevin mentioned, you should follow the user's guide of LAUNCHXL-F28069M and BOOSTXL-DRV8301, just use the 3.3V power supply from either LAUNCHXL-F28069M or BOOSTXL-DRV8301.
