Introduction
Bootloaders are a common part of MCU system design. A bootloader makes it possible for a product's firmware to be updated in the field. At the factory, initial programming of firmware into a product is typically done through the MCU’s Joint Test Action Group (JTAG) or Serial Wire Debugger (SWD) interface. However, these interfaces are usually not available in the field.
This is where bootloading comes in. Bootloading is a process that allows you to upgrade your system firmware over a standard communication interface such as USB or I2C. A bootloader communicates with a host to get new application code or data, and writes it into the device’s flash memory.
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 I2C Bootloader for PSoC 3 and PSoC 5LP, AN60317 - PSoC® 3/PSoC 5LP I2C Bootloader should get you going.
Since the projects involve the use of USB component, in case of PSoC 5LP it is mandatory to use an external 24 MHz crystal.
The Bootloader GUI provided with this App Note has been tested to work on full-fledged Windows operating system only.
The GUI is not tested and not guaranteed to work on Virtual machines.
