To use FreePascal for bare metal programming on the Raspberry Pi we first need a FreePascal cross compiler.

  • download and install arm compiler as used in: http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/ok01.html
  • add the following bin folder on your path
    • export PATH=$PATH:$HOME/fpc-2.6.0/bin
    • export PATH=$PATH:$HOME/arm-2008q3/bin
  • in the freepascal bin folder copy pp386 to ppcppc
  • download the freepascal 2.6.0 sources
  • make the cross compiler be executing the following command
    • make crossinstall CPU_TARGET=arm OS_TARGET=linux CROSSBINDIR=/arm-2008q3/bin OPT=-dFPC_ARMEL INSTALL_PREFIX=/build NOGDB=1 BINUTILSPREFIX=arm-none-eabi-
