Yes,

I even can’t finish LAB1,because the EVM no responded.

I have question: when turn the power, what is display on EVM?

Xiao,

The LED display on the board shows the output voltage from one of the two buck stages (selected by a switch). The display is un-powered until a +9V supply is connected to the input jack and the DC Bus power is switched on (see the top slide on p.9 in the manual), so it will not display anything.

You do not apply power in lab 1 so it is normal for the display to be blank then. Power is not needed until step 18 of lab 2. How far did you get in the lab instructions?

Regards,

Richard

Lab1 can't connected EVM. See previous attachment.

Xiao,

The screen capture in your post shows the board has connected, the project loaded, and the program counter is at the start of main waiting for you to run or step through the program. This is what you should see after step 28 in Lab 1.

"(Suspended - SW Breakpoint)" indicates the debugger is connected and halted.

Can you elaborate on what's wrong please?

Regards,

Richard

I'm concerned about this line . Please explain what it means: "Texas Insruments XDSv1 USB Debug Probe/CIA_0 (Disconnected : Unknown)"

Xiao,

The device you are using contains two cores: a C28x CPU, and a Control Law Accelerator (CLA). Each is an independent computer core which can be connected separately from the other. In Lab 1, we only use the C28x core: the CLA is not needed so it remains disconnected.

In Lab 5 you will learn how to connect and load code onto the CLA.

Regards,

Richard
