6.3 Developing Applications for PSoC 5LP
The PSoC 4 Pioneer Kit has an onboard PSoC 5LP whose primary function is that of a programmer
and a bridge. You can build either a normal project or a bootloadable project using the PSoC 5LP.
The PSoC 5LP connections in the Pioneer board are summarized in Figure 6-30. J8 is the I/O con-
nector (see section 4.3.7 PSoC 5LP GPIO Header (J8)). The USB (J10) is connected and used as
the PC interface. But you can still use this USB connection to create customized USB designs.
The programming header (J7) is meant for standalone programming. This header needs to be
populated. See the 'No Load Components' section in A.6 Bill of Materials (BOM) on page 108.

6.3.1 Building a Bootloadable Project for PSoC 5LP
All bootloadable applications developed for the PSoC 5LP should be based on the bootloader hex
file, which is programmed onto the kit. The bootloader hex file is available in the kit files or can be
downloaded from the kit web page.
The hex files are included in the following kit installer directory:
<Install Path>\CY8CKIT-042 PSoC 4 Pioneer Kit\
<version>\Firmware\Programmer\KitProg_Bootloader
