MSP430 FET overcurrent error

Other Parts Discussed in Thread: MSP430F6779A, MSP-FET, MSP430FR4133

Hi all,

I am using MSP-TS430REU128 USB board with MSP430F6779A controller. I am getting the following error on CCS Version: 6.1.3.00033 ,  "error initializing emulator: Your connected hardware  might drain too much power from the debugger. This results in an overcurrent." Tried to update the firmware(as suggested)  but it would not even do that.

I just have a crystal connected to controller, there is nothing else connected to it. I faced this problem earlier and had to restart my system and it worked. Now even after restarting the system several times it does not work. I am working on Windows 10.

Any help would be appreciated, thank you.

    Hi Ashish,

    I'm going to look into your issue.

    1. Are you using the MSP-FET430UIF (a grey box) or the MSP-FET (a black box)?

    2. Can you check the orientation of your device in the socket on the board - the dot on the device for pin 1 should be in the same corner as pin 1 is labeled on the pins on the edge of the target board.

    3. Can you tell us what position all jumpers on the target board are in?

    4. Does the device or board seem hot? That could indicate a short somewhere.

    Hi Katie,

    1. I am using MSP-FET ,black box.

    2. I checked the orientation of the chip and it is correct.

    3. The jumper positions have not been changed. JP1 has two pins and a jumper on it, JP2 no jumper, JP3 jumper is in int position, JP4 has two pins and jumper on it,JP5/6/7/8/9/10 have jumpers on position 1 and 2, JP11/12/13 have jumpers on position 1 and 2.

    4. The board and the device don't seem to be hot.

    Also I was able to use the emulator yesterday but today it is not working. I have even tried uninstalling and reinstalling CCS , still no luck.

    Thank you.

    Hi Katie,

    I swapped the MSP-FET (black box) with another one that we had and I am able to work with the micro controller. So I think MSP-FET has gone bad. Is it covered under warranty and could it be replaced?

    Thank you.

    Hi Ashish,

    I talked to the team that maintains our tools. They mentioned that if you don't have the latest tools update for CCS you might see an issue like this. Can you open CCS and go to Help > Check for updates to make sure that you aren't missing any MSP tools updates for CCS?

    Hello Katie,
    I have a similar problem. I use MSP430FR4133 launchpad and upon debugging my code, the following error message was displayed: MSP430: Error initializing emulator: Your connected hardware might drain too much power from the debugger.This results in an overcurrent.

    I have a 165 Ohm resistor connected on one end to P8.0 (A8) for analog input and GND on the other end on the launchpad. This resistor is in turn connected to GND on the Vrps and one end to multimeter.

    Kindly help me out.

    Best,

    Hi Shubhankar,

    How do you have P8.0 set in your code (or have you not been able to load code yet due to this issue)? If you remove the resistor does the issue stop? I'm thinking if your code (or whatever was previously loaded in the device from before) sets P8.0 to output high for example, then the resistor to GND could cause a lot of current since it is not very large - e.g. if you have 3.3V Vcc and a 165 Ohm resistor by Ohm's law that's 20mA of current, which is too much.

    Regards,
    Katie
