Table 2. Flash Loader Code Layers
Metrics
The Flash Boot Loader requires about 4 KB of Flash
and program space and under 1 KB of RAM. The
code is written in C for easy maintenance and
portability, or for integration into another method of
Flash programming.
Flash Loader Code Features
The program (Flash) and data (RAM) sizes for each
layer are computed based on the following ZDS II
settings:

layers.
As shown in
standard libraries occupy most of the code space.
However, this code space can be reduced if the user
chooses to write a slimmed-down version of the
standard libraries.
When excluding the standard libraries and the user
interface, the Flash Loader requires around 4 KB of
Flash and 1 KB of RAM. This reduction can be
further optimized by observing the small memory

Testing
The Flash Loader program discussed in this
application note was tested successfully with the Z8
Encore! XP Z8F642 MCU Development Kit
(Z8F64200100KIT). ZDS II for Z8 Encore! family of
microcontrollers is used to build the Flash Loader.
With this setup, IHX file downloads can be
efficiently executed.
