    Hi Charles,

    Thanks for your email, 

    could you please share us the EVK reference schematic files for TM4C1233H6PZI for HW development,

    and how we can select the booting option through HW pins - bcz we have booting options like MMC card/external EEPROM/internal flash etc , please let us know

    We only have LaunchPad EVM for TM4C123. You can find the product page at: https://www.ti.com/tool/EK-TM4C123GXL

    At the bottom of the user's guide, you can find the schematic and BOM for the LaunchPad board. See below link.

    Please refer to the datasheet for details about the BOOTCFG register. This is a non-volatile register that can be programmed one time to configure how you want to boot through a pin activation. You can configure one of the GPIO pins for your specified polarity to force the bootloader to activate. 

    Please refer to the Bootloader user's guide for details. https://www.ti.com/lit/pdf/spmu301

    There are bootloader examples in TivaWare library. I will suggest you start with the serial bootloader. You can find this UART serial bootloader at: C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl\boot_serial. There is also a simple application that goes along with this bootloader demonstration. The application can be found in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl\boot_demo1. Basically, after the bootloader (boot_serial) is running, it will try to download the application firmware (boot_demo1) through the UART port.  I will suggest you start with boot_serial to get a feel for how it works.
