in need: Dev board with trace-ability

Hi,

I´m unable to find a real sticky problem... I´m using a TMS 570LS20216ASPGE which cannot be traced.

The project should be working without additional hardware - so all i need (for christmas) is a working toolchain with trace-ability. Is there a ready-to run board including a TMS570 BGA ?

 

all the best

Dominik

    Dominik,

    Sorry for the late reply.

    You can order an TMS570 MDK from Keil. It supports connections to ETM tracing.You can order ETM tracing tools from Lauterbach.

    Before you getting the tracing tools, I would suggest the following to make debugging a little easier.

    (1) Replace instruction at address 0x0 with "b #-8". With this change, CPU is "locked" to address 0x0 after reset. When connect debugger to CPU, everything on the device is held to the default states. In TI CCS, you can use restart button to move PC to c_int00. This make your debugging sessions repeatable.

    (2) Insert I/O pin toggling in your application at the important processing locations. You can use a scope to check the timing and occurrence of these signals to narrow down the problem. Even with a tracing tool, you still need some other indicators to locate the instructions and timing when the problem occurred.

    Thanks and regards,

    Thanks very much for the great reply !

    Just one more question: i can´t find the lauterbach tools to be supported within CCS ("=>Porperties=>General=>Connection" does not list this device).

     

    Thanks very much

    Dominik,

    have a look at this forum thread http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/109516.aspx

    However, if you purchase Lauterbach emulator, you will also get quite user-friendly IDE alhough not based on Eclipse AFAIK.

    Cheers, Jiri
