flash code in custom board of tm4c123gh6pm using tiva launchpad

Other Parts Discussed in Thread: TM4C123GH6PM

Hello,

I developed my prototype using Tiva Tm4c123gh6pm launchpad. Now I want to make my custom board by deleting debugging side part.

I had gone through "Graduating from Tiva Launchpad to a custom design - How do I program it?" thread also the following wiki link

http://processors.wiki.ti.com/index.php/Stellaris_LM4F120_LaunchPad_Debug_How_To

they have suggested to connecting  JTAG pin of launch pad with custom board headers. but by doing so my 2 controllers will get connected with single boot-loader, However that connection with 2 tm4c123gh6pm chip simultaneously will create problem in flashing code in my custom board?? 

connecting  JTAG pin of launch pad with custom board through header link will solve issue??

thank you

    Hello Harshal,

    If you go through the description in the wiki page for "DEBUG OUT", the intent is to disable the Main MCU and be able to get the JTAG and UART signals from the ICDI MCU to the custom board. So this way the device will jot interfere with the custom board that you have.

    Regards
