Bootloading is a process that allows you to upgrade your system firmware over a standard communication interface such as USB, I2C, UART or SPI. A bootloader communicates with a host to get new application code or data, and writes it into the device's flash memory.
This application note describes an I2C based bootloader for PSoC 3 and PSoC 5LP. To get introduced to basics of PSoC 3 and PSoC 5LP Bootloader please refer AN73854 - PSoC® 3 and PSoC 5LP - Introduction to Bootloaders. If you intend to learn how to develop USB Bootloader for PSoC 3 and PSoC 5LP, AN73503 - USB HID Bootloader for PSoC® 3 and PSoC 5LP should get you going.
