TMS570LC43 Hercules Dev Kit Newbie issue

Other Parts Discussed in Thread: HALCOGEN

I'm experimenting with the TMS570LC43 Dev Kit, and I'm having problems getting off the ground. Here is where I stand:

1) Latest CCS6 and the debugger/USB serial drivers install fine.

2) With the target configuration to the XDS100v2 emulator configured the "test connection" works.

3) I created a debug hello world demo project, and it compiles fine.

4) From the context menu for the project, select the binary, and start a debug session.

5) I get messages about writing to the flash, and then it just sits there. 

I was expecting it go to the first line of main, and wait for me to step. Instead, I see in the debug window that it's "running" but there is only the stop and pause buttons available.

I'm looking for help to get me started.

    Hi Timothy,

      I will suggest you to start with the built-in examples from HalcoGen. The Hello world example may not be the best example as it does not properly initialize the microcontroller. HalcoGen will automatically generate the initialization, drivers, api for you.

    Timothy,

    Also what messages are you getting when you try to write to flash?  Screenshot would help or copy/paste from the console window...

    There is a new flag that has to be checked to make flashing work reliably on the LC4357 - it is under the debug node of the project properties.  There is a choice for 'Flash Settings" and if you pick this it displays a checkbox "System Reset On Connect".  You should have this box checked for the LC4357.

    Also you should probably have "Auto ECC Generation" checked while you are at it unless you took some extra steps to create linker generated ECC.  If you have a doubt about this you can check the linker.cmd file and see if there are ecc sections in it.  If not then you need Auto ECC Generation checked because ECC is always enabled on the LC4357.

    Thanks for the tip. I followed the blinky example, and generated code. Is the TI Way to copy it to a CC6 project?

    Hi Timothy,

      Once you generate the code in HalcoGen, you just need to create the same project name in CCS and you will immediately see all the files in the CCS Project Explorer under the created project name. Before you compile the code, make sure you have the proper include path setup.

    Okay, got the example working. Thanks...

    Interestingly, there is a misprint in the HALCoGen blinky example that sidetracked me for a bit.

    The text for step 3 says to "Map VIM Channel 2 to IRQ", but the image in the help shows it connected to FIQ. I followed the picture, and got no blinking. Once I switched to IRQ, it worked.

    Hi Tim,

      Yes,it is a mistake in the text section of the example. It should map to IRQ.

    It's actually in the image. The text is right.
