#Overview
Raptor is a full SoC reference design for IoT applications based on the Arm Cortex M0 CPU core targeted on the X-FAB XH018 process (180nm). Raptor provides means to interface with analog and digital sensors as well as external RF radio (WIFI, Cellular, Bluetooth, etc.,) modules needed for IoT applications.
The reference design is based on an SoC design template and can be modified, compiled and simulated through the SoC Editor tool with CloudV on the Efabless platform. The reference design comes with basic device drivers for all on-chip peripherals as well as set of applications to test and demonstrate Raptor capabilities.
Instances of the Raptor Design Template can be configured through the Design Request Form. A configuration file is generated upon saving the form and can be used as a starting point for generating a reference design or to request a turn-key delivery of a custom SoC through design partners on the Efabless platform.
Below is the block diagram for a Demo Chip configuration taped-out for Raptor. The design files for project include an instance of Raptor based on the configuration shown below.
##Project Contents This project contains the design files for Raptor EVB, an evaluation board with a fully implemented SoC based on the Raptor template. The pcba design files are based on Kicad.
The project also contains firmware example code using the Raptor EVB board.
#Hardware
#Firmware
The firmware examples can be built from their respective directories through the makefile. The building the image files requires install the gcc arm compiler. Download install packages for the compiler can be found on the Arm Developer Web Site.
###To program the SPI flash chip:
- Install the pyftdi python library
pip3 install pyftdi
- Configure the board for flash programming.
Install jumpers on across pins 2 & 3 on the four 3-pin headers
next to the USB connector.
Ensure the jumper for usb to Raptor uart are not installed
(two 2-pin headers next to USB)
- Change to the directory for the target firmware
make clean hex flash
- Configure the board for processor operation
Move jumpers on across pins 1 & 2 on the four 3-pin headers
next to the USB connector.
