Dear specialist: Today I update the version of plecs as well as the version of c2000 tool, and I tried to build the plecs model, but I found out that the launchpad cannot be build as normal, the error occured as: So how to solve the problem since it indicates that my dsp controller is reset? I toggled the reset button of the DSP controller but still it doesn’t work.

Were you able to fix it? I would try the UniFlash GUI to connect to the LaunchPad. Once it works there, it will most probably work with PLECS. ---

Is your LaunchPad connected to any external hardware? What are the position of the DIP switches in S1 - are they oriented towards or away from the MCU? Can you program the device if it’s only connected to your computer? Do you have a second LaunchPad you can use for testing? TI has a debugging section on their website related to this error that describes other reasons you may see this error and potential resolutions: [https://software-dl.ti.com/ccs/esd/documents/ccs\_debugging\_jtag\_connectivity\_issues.html#device-is-held-in-reset](https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html#device-is-held-in-reset)
