Introduction

OCEOS is provided as an object library, documentation and example source code.
Setup for the use of OCEOS requires the user to prepare the development environment. At a minimum this requires the installation for compilers, debug tool, editors, …etc.

The OCEOS build and test environment requires the following:

  1. SPARC Build environment (compiler, linker, libraries, etc.) Download here.
  2. ARM Build environment Download here and Download here
  3. Debug software tool e.g. OCE’s DMON. Evaluation download.

Building the example application

OCE Technology provides sample make files that can be used by application developer. Those files are located in demo projects of Examples folder. If make is called from one of the demo projects, than user requires only to modify variable TOOLCHAIN_PATH in tools_config_arm.mk to point to toolchain folder. User can use make files to build project for one of the supported development board. User requires to modify make files to add own development board. Make file available parameters for ARM:

  • Build target: all
  • ARM_BUILD=1
  • TOOLCHAIN=armclangv6|gcc|segger|iar
  • RELEASE=0|1
  • MCPU=cortex-m3|cortex-m7
  • BOARD=ATSAM3X8E|ATSAMV71Q21
  • FPU=0|1
  • SAMV71_CONSOLE=0|1
Example:
make all FPU=1 TOOLCHAIN=gcc RELEASE=1 MCPU=cortex-m7 BOARD=ATSAMV71Q21

Make file available parameters for SPARC:

  • Build target: all
  • TOOLCHAIN=gcc|clang
  • RELEASE=0|1
  • MREX=1
  • BSP=gr716|pm698|gr712rc|gr740|agga4|at697
Example:
make all TOOLCHAIN=clang BSP=gr716
or 
make all TOOLCHAIN=clang BSP=gr716 MREX=1
