C2000-GANG: Power supply problems when using C2000-GANG programming.

Part Number: C2000-GANG

First of all, I only provide a power supply to the C2000-GANG, there is no supply of MCU to the 3.3V power supply, so that it can not be successful to MCU programming. When I give the MCU power supply can be programmed.In other words, the use of C2000-GANG requires two power supply.(I don't know if this is the right thing to do,But only in this way can be achieved using C2000-GANG programming.)

I found that the use of JTAG online simulation must also provide additional power to the target MCU. This is the same as C2000-GANG, Do I have to use it in this way(two power)?

So I have a question that why not use the C2000-GANG or JTAG to target MCU power supply,Isn't it more convenient?

If you have any suggestions, please let me know. Thank you very much!!!

    Hi,

    The C2000-GANG programmer can supply target device with 3.3V, but the supply current is limited to 150 mA per target. If your target taking more current then you need to use your external power supply for powering your target device. See manual for details.
