Beginning with PSoC Creator 2.1, the bootloader system has been reorganized to provide more configuration options. In previous releases, the bootloader system was part of the cy_boot component (a required component that is automatically and invisibly instantiated in all designs). From PSoC Creator 2.1 onwards the bootloader component is separated from cy_boot component and is available as a separate component in component catalogue. Please refer Chapter11.Bootloader Migration’ in System Reference Guide (Help>Documentation>System Reference) to know how to migrate your older versions of bootloader/bootloadable projects to PSoC Creator 2.1.
Bootloading is a process by which you can upgrade your system firmware over a standard communication interface such as USB or I2C. The bootloader manages the process of updating device flash memory with new application code, data, or both. It also contains an interface such as USB that communicates with the bootloader host to get the new application code and data.
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.
