I thought it would be cool to see how long it takes to make a boot-able Raspberry Pi disk using ELLCC. This is a timed experiment. In the end we’ll have an SD card that can be booted on the Pi. First, get a binary ELLCC release:
[~/ellcc-release] dev% mkdir test [~/ellcc-release] dev% cd test [~/test] dev% wget http://ellcc.org/releases/ellcc-x86_64-linux-eng-0.1.27.tgz --2016-01-12 22:00:19-- http://ellcc.org/releases/ellcc-x86_64-linux-eng-0.1.27.tgz Resolving ellcc.org (ellcc.org)... 184.108.40.206 Connecting to ellcc.org (ellcc.org)|220.127.116.11|:80... connected.

Second, check what the options are:
[~/test] dev% cd ellcc/libecc/ecclinux/ [~/test/ellcc/libecc/ecclinux] dev% ./build usage: ./build [options] target options: -packages 'packag1 package2 ...' Specific packages to build -exclude 'packag1 package2 ...' Specific packages to exclude -extras Include additional packages -clean Clean up a previous build targets: help This message bcmrpi Raspberry Pi (ARMv6) bcm2709 Raspberry Pi 2 (ARMv7) available packages: kernel sinit sbase ubase smdev nldev nlmon svc sdhcp loksh ntfs3g iproute2 e2fsprogs vim dropbear extra packages: ellcc packages not buildable on the Mac: uboot iproute2 e2fsprogs vim
Third, build an image for the Pi 2 that includes the ELLCC tool chain (-extras):
[~/test/ellcc/libecc/ecclinux] dev% ./build -extras bcm2709j ...
Fourth, insert an SD card and install:
[~/test/ellcc/libecc/ecclinux] dev% su Password: [root@dev ecclinux]# ./install Warning! This command will destroy all data on /dev/sdc. Continue? [yes/no] yes ...
Put the SD in the Pi and boot. Voila!This entry was posted in ELLCC and tagged ARM, Cross Compiling, Linux, Raspberry Pi on January 13, 2016 by rich.
