Introduction
SPI-DirectC is designed to support an embedded In-System Programming for Microchip devices. In-System Programming refers to an external processor on-board programming one of the IGLOO®2, SmartFusion®2, PolarFire® or PolarFire SoC devices using a SPI peripheral interface.
SPI-DirectC supports systems with direct and indirect access to the memory space containing the data file image. With paging support, it is possible to implement the embedded ISP using SPI-DirectC on systems with no direct access to the entire memory space containing the data. Paging support is accomplished by making modifications to the data communication functions defined in dpuser.h, dpcom.c, and dpcom.h.
To use SPI-DirectC v2021.1, you must make some minor modifications to the source code, add the necessary API, and compile the source code and the API together to create a binary executable. The binary executable is downloaded to the system along with the programming data file. The programming data file is a binary file that can be generated by Libero® SoC Design Suite version 11.2 or later. For more information on detailed specification of the programming file, see Data File Format.
