Odroid

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 libgtk2.0-dev libgdk-pixbuf2.0-dev libpango1.0-dev subversion
#build-essential may also be necessary

• Download fpcup_linux_armhf (or perhaps fpcup_linux_arm) and fpcupodroid.ini into a directory (say ~)
• Make fpcup executable:

chmod ug+rx fpcup_linux_armhf #replace filename with proper name if different

• 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

Use the same command for updating.

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. Contributions for relevant settings in fpcupodroid.ini welcome.
• (general fpcup problem) you may have to rebuild Lazarus yourself (Tools/Build Lazarus) to get all packages/controls fpcup installed for you.
• (fpc problem) Problems building LazReport package with current FPC trunk: see bug http://bugs.freepascal.org/view.php?id=25639. Workaround: disable LazReport and rebuild Lazarus manually
