Other Parts Discussed in Thread: TMS570LS1224, HALCOGEN

Tool/software: Code Composer Studio

Hello,

I have made my own board with TMS570LS1224 micro-controller and I program the code with XDS100-v2 emulator.

When I click run and debug button in ccs, I get this error:

I made these changes: In debug mode of ccs when running the code went to Tools->On Chip Flash and selected "Entire Flash" checkbox. Then I clicked the very bottom "Erase Flash" button. Also I checked Tools->ARM Advanced Features weather the enabled checkbox is enabled.

But when I reprogram the board, nothing changed as below:

And this is disassembly if helps:

Can someone help please?

    Hello,

    I don't see any error messages, only debug messages about the memory map setup from GEL. As for more details, I will bring this thread to the attention of the device experts

    Thanks

    Hello Ki,

    My code is just the sci example of HaLCogen which it has to display some words like "HERCULES" but neither in terminal nor in variables I get nothing.

    I thought it is because of this sentence. So where am I taking a mistake in reading the data?

    The code is as below:

    6428.sci.zip

    Hello,

    Can you please use our example code of project0 to check if microcontroller works as expected? BW, does the terminal have the same baudrate setting as baudrate used in your code?

    Hello,

    I checked the terminal's details and was the same as my code design but there is a question:

    I have just connected an XDS100 emulator and not sci pin to my laptop but the example says:

    "Connect the SCI port of the micro to the COM port of the personal computer with MS Windows."

    Does it mean that I have to connect that pin or it is already connect via the emulator?

    The standalone xds100v2 emulator does not support UART. The on board xds100v2 on TI HDK supports and xds110 on TI Hercules Launchpad support JTAG signals and SCI signals. You need to connect the SCI to PC serial port through a RS232 driver.
