Hi,

I want to flash the MCU(LM4F232) via serial port(UART0) i.e. how to configure UART bootloader.

What does example codes boot_demo1 & boot_serial meant for?

Best Regards,

Santosh.

    The document \\docs\SW-BOOTLDR-UG-xxxx.pdf, provides the info on how this can be done.

    You can read the readme file and code comments where the example program is located, to get an idea on what these example programs are meant for.

    Hi Santosh,

    You can also find a good amount of information in the User's Guide for the EK-LM4F232 (SW-EK-LM4F232-UG-xxxx.pdf). If you look at the sections for boot_serial and boot_demo1, you can find instructions about how they work together. Essentially, boot_serial shows how to configure a UART boot_loader based in flash, and boot_demo1 is an example app that you can load with this boot loader.

    The LM4F232 also has UART boot loader capabilities in ROM that activate on a RESET event if the flash is empty. You can read about this in the ROM User's Guide: http://www.ti.com/lit/ug/spmu348/spmu348.pdf

    If you have any difficulty getting these to work, please let us know.

    Regards,

    Christian
