Hi,

Please refer to the boot_emac_flash example. This is an ethernet bootloader example that will use uIP stack (not TCP/IP) to communicate with the TFTP server. The LM flash programmer will act as both a BOOTP as well as the TFTP server to download new code to the MCU via Ethernet. If you are using Linux then the LM flash programmer will not work as it is a Windows based application. For linux you will need to the eflash tool. The eflash tool source code can be found in <TivaWare_Installation>/tools/eflash folder and the executable for Windows is in <TivaWare_Installation>/tools/eflash/bin/eflash.exe.

Hi,

You can find under <TivaWare_Installation>/examples/boards/ek-tm4c1294xl/boot_emac_flash. Import this project into your workspace and you will find the boot_loader folder which is link to the boot_loader library. The bl_emac.c file has the functions to communicate with the TFTP server.
