EKK-LM4F programming remote device

Hello,

   Apologies if this is in the wrong place, I could not add a new post to the development tools forum because there was no relevant subgroup that allowed me to post.

I have an EKK-LM4F232 eval board, and have been using it to develop my application for a project board that has the 64 pin version of this part.  I have been able to program flash on the eval board microncontroller, but now need to program the device on my project board.

I have searched for days on the ti.com knowledge base, forums, application notes and user manuals for the eval board.  I cannot find anything that describes if and how the eval board can be used to program my project board device.

On the eval board user manual schematics, I can see a 10 pin connector called external debug, which I assume can be used for this purpose, but nowhere can I find any description of how to do this or configure either Keil or the LMFLASH utility.

Can someone tell me if this board can be used for this purpose, and if so, point me to a document that describes the process.

Thank you

Robert Morrison

  • Robert,

    While we designed most of the LM3S eval boards to act as debuggers, as well, we did not do this for the first LM4F eval board.  You will see this functionality come back in future LM4F eval boards.  The 10 pin connector that you see on the EK-LM4F232 board is intended for connection of an external debugger, in the event that you do not want to use the built-in ICDI interface.

    Sorry for the inconvenience.

    Regards,

    Bret

     

  • OK, thank you for this information.  What is the recommended way of programming and debugging the device on my project board?  I brought out the JTAG pins to a connector on that board, is there a recommended JTAG device that I can use with the Keil debugger?

  • Robert,

    You could use one of the LM3S eval boards to debug your target board.  The EKK-LM3S811 board is an inexpensive option ($49) and will work with the Keil debugger (just ran it here at my desk).  More info at:
