Overview

Odroid are ARM devices manufactured by HardKernel.

U2, U3

These devices contain a Samsung ARM chip

  • instruction set: ARMv7A
  • floating point coprocessor (FPU): VFPv3

Operating systems: Xubuntu (ARMHF; hardfloat), Android.

Installing FPC/Lazarus using fpcup

This section focuses on using Linux on the Odroids.

  • FPC 2.6.x

As the provided Linux is ARMHF, standard FPC 2.6.x is not suitable (insufficient ARMHF support0. The included Xubuntu Linux probably supplies modified FPC 2.6.x+Lazarus (much like the Raspbian distribution).

  • FPC trunk

The easiest way to install FPC trunk and Lazarus is to run fpcup which will use a 2.6.x bootstrap compiler to build a trunk ARMHF intermediate compiler. Now the regular FPC and Lazarus environments are built by fpcup.

Note that fpcup is a thin wrapper around the regular svn/make FPC/Lazarus install process, so if you're uncomfortable with this process, it may not be for you.

Instructions - to be run as a regular user:

  • Install prerequisites for Lazarus and subversion, e.g. something like:
sudo apt-get install build-essential libgtk2.0-dev libgdk-pixbuf2.0-dev libpango1.0-dev subversion
  • Download fpcup_linux_armhf (or perhaps fpcup_linux_arm) and fpcupodroid.ini into a directory (say ~)
cd ~
wget https://bitbucket.org/reiniero/fpcup/downloads/fpcup_linux_armhf
  • Make fpcup executable:
chmod ug+rx fpcup_linux_armhf #replace filename with proper name if different
  • Get the fpcupodroid.ini configuration file:
wget https://bitbucket.org/reiniero/fpcup/downloads/fpcupodroid.ini
  • Run fpcup, telling it to use the [General] profile in fpcupodroid.ini:
./fpcup_linux_armhf --inifile=fpcupodroid.ini #replace filename with proper name if different

For updating: 

./fpcup_linux_armhf --inifile=fpcupodroid.ini --inisection=update #replace filename with proper name if different

fpcup will create desktop shortcuts etc. For more details, please see the fpcup wiki page.

Notes:

  • currently fpcup will do a make distclean before installing/updating, which may stress your memory card. Experimental fix in [update] section (see above)
  • (general fpcup problem) you may have to rebuild Lazarus yourself (Tools/Build Lazarus) to get all packages/controls fpcup installed for you.
