Ultibo core is an embedded run-time platform and development environment written specifically for creating applications with small single board computers. It is built around the Free Pascal compiler and the Lazarus integrated development environment. Ultibo core is an RTL written entirely in Free Pascal and designed to make embedded or bare metal development accessible to all.

Installation

Windows

A Windows installer is available and full source plus a large collection of examples is included.

macOS

 make distclean OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/
 CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH"
  • type and wait:
 make all OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/ CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH"
  • type and wait, assuming your FPC 3.1.1 is in the folder /usr/local/lib/fpc/3.1.1/ so option INSTALL_BASEDIR becomes INSTALL_BASEDIR=/usr/local/lib/fpc/3.1.1/
 sudo make crossinstall CROSSBINDIR=~/Documents/gcc-arm-none-eabi/arm-none-eabi/bin/ CROSSOPT="-CpARMV7A -CfVFPV3 -CIARM -OoFASTMATH" OS_TARGET=ultibo CPU_TARGET=arm SUBARCH=armv7a INSTALL_BASEDIR=/usr/local/lib/fpc/3.1.1/


Linux

An installation script is available for Linux, full source plus a large collection of examples is included.
