AN84401 describes a SPI-based bootloader for PSoC® 3 and PSoC 5LP. In this application note you will learn how to use PSoC Creator™ to quickly and easily build SPI-based bootloader and bootloadable projects. It also shows how to build a SPI-based embedded bootloader host program.

简介

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 a SPI 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 and I2C Bootloader for PSoC 3 and PSoC 5LP, AN73503 - USB HID Bootloader for PSoC® 3 and PSoC 5LP and AN60317 – PSoC 3 and PSoC 5LP I2C Bootloader  respectively should get you going.
