Introduction
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.
