EK-TM4C123GXL DFU Boot loader

Prodigy 50 points


Hey!

I have loaded boot_demo1 on my LaunchPad with CCS and I  can load successfully a .bin through serial or usb (DFU) with LM Flash Player.
However, the loaded program will not launch if I do not set its address at 0x0.

I have two questions. How can I make the .bin work (for example blinky) and not erase boot_demo1?
Is it possible to modify the boot loader to get and use a .bin on a plugged USB stick?


Thanks for your help!

    Hello Geoffrey,

    The boot demo is supposed to work with a Flash based boot loader. The Flash based boot loader resides at 0x0 and hence gets executed. It is this boot loader which takes the incoming application and loads it to a non 0x0 location, then does a jump to the application.

    The Flash based boot loader is by the example name of boot_serial and boot_usb in dk-tm4c123 examples directory.

    Regards
