4.1 LFU Bootloader and Application Projects

In this application note, three projects are used as described in Table 4-1.

Table 4-1 Projects Needed in This Demo
CCS Projects Description
LFU Bootloader This is a FreeRTOS based bootloader software and is around 16 KB in size, it is allocated to the starting address of main Flash memory.
On a new device, this bootloader needs to be programmed via SWD interface first before starting firmware upgrade process.
Application code 1 This is application code 1 for firmware upgrade demo, it uses application space 1 (0x04000 - 0x11FFF) for function.
Application code 2 This is application code 2 for firmware upgrade demo, it uses application space 2 (0x12000 - 0x1FFFF) for function.
