Tiva C on "device mode" not debug

Other Parts Discussed in Thread: EK-TM4C123GXL

Hell Community.

I have been playing around with a EK-TM4C123gXL I can get my code running and debug nicely in Keil or CCS.

But now I want to take it a step further. I want to run the code in "Device Mode" without Debug. Hopefully then I can power up the board from a powerbank and do something fun with it.
Do I need to generate a release version of the code and load it via the Device USB or do I from the Debug mode and then in CCS for example go to:  Run, Load, Load Code?

And will it make any deference?


Thank you in advance.

    Hello Ruslan

    The code that you have running can work as is. The difference between using the Device USB v/s Debug USB is that Debug USB uses JTAG allowing to the download the code N times (N is the flash endurance). The Device USB side requires a flash based boot loader or some mechanism to invoke the USB DFU so that code may be loaded again.

    Hello Amit,

    Thank you for your answer. Do I write a bootloader myself. I have seen some user guides from TI. Or is there a boot loader that supports your products (a programmer)?

    Regards

    Hello Ruslan,

    When the flash is in erased the ROM boot loader is automatically invoked. If you want to write a flash based boot loader then you may refer to the dk-tm4c123g boot example in TivaWare. The next TivaWare will have the example for EK-TM4C123GXL as well.
