r0ket

This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong.
<note important>** You //might// want to disable .DS_Store files on (network) mounts**
...otherwise Mac OS will break your r0ket file system.
**NEVER EVER access the r0ket with the finder.**
Always use only the terminal.

====== Build environment on Mac OS X ======

===== 1. Compiler =====

== Using Mac OS X: == 

<note tip>
The CodeSourcery G++ package provides a GNU cross-compiler toolchain for ARM. The Mac OS X version is not distributed by CodeSourcery in binary form, but can be built from source code, or mainline gcc for arm-none-eabi can be installed via MacPorts.
</note>

=== Solution 1 ===

  * This explains how to build the tool chain on a Mac: [[https://github.com/jsnyder/arm-eabi-toolchain|Git project: jsnyder / arm-eabi-toolchain]]
  * You will probably want to add this line to /etc/bashrc, so that the tools are always accessible when you open a new Terminal: <code>export PATH=$HOME/arm-cs-tools/bin:$PATH</code>

=== Solution 2 ===

<note tip>
This "Solution" produces slightly bigger code (with gcc 4.6.2) compared to older gcc versions. Therefore you can not compile some l0dables. This results in errors like:
<code>arm-none-eabi-ld -nostartfiles -T loadable.ld -o mp0ng.elf mp0ng.o  -lc -L/opt/local/arm-none-eabi/lib/
arm-none-eabi-ld: mp0ng.elf section `.text' will not fit in region `sram'
arm-none-eabi-ld: region `sram' overflowed by 148 bytes</code>
</note>

  * Install [[http://macports.org|MacPorts]]
  * Don't forget <code>sudo port sync</code>
  * Install the port ''arm-none-eabi-gcc'': <code>sudo port install arm-none-eabi-gcc</code>

=== Solution 3 ===
  * Currently not working (at least on Lion). Less pain: MacPorts
  * Install [[http://mxcl.github.com/homebrew|Homebrew]]
  * Import (as in copy to /usr/local/Library/Formula) the formulae for cloog-ppl and arm-none-eabi-gcc from [[https://github.com/jpc/homebrew/tree/master/Library/Formula|here]] 
  * Install the formula ''arm-none-eabi-gcc'': <code>brew install arm-none-eabi-gcc</code>


== Another option: Installing Ubuntu Linux in a VirtualBox: ==
  * [[http://www.tuaw.com/2009/09/07/how-to-set-up-ubuntu-linux-on-a-mac-its-easy-and-free/|Article: How to set up Ubuntu Linux on a Mac -- it's easy and free]]
  * Then refer to the [[build?&#compiler|main Build article]].

===== 2. Source =====
see [[build?&#source|main Build article]]

===== 3. Build =====
see [[build?&#build|main Build article]]

===== 4. Deploy =====
Bring the r0ket into ISP-Mode:
e.g. by using Method 1 (up to 30 seconds, but works always)
  * Power off r0ket
  * Press and hold button “Left”, power r0ket on
  * Connect r0ket via USB

Mac OS X will show a "CRP DISABLD" USB device. 

== Using the Mac OS X Terminal: ==

<code>cp firmware.bin /Volumes/CRP\ DISABLD/</code>

Note: Copying the firmware.bin over to the device in the Mac OS X Finder does __not__ work.

== Using the Ubunto Terminal in a VirtualBox: ==

Share the directory "CRP DISABLD" on the Mac OS X host with VirtualBox, e.g. using the name r0flash - it will be available on the Ubuntu guest at /media/sf_r0flash.

Copy the file firmware.bin to that directory:
<code>cp firmware.bin /media/sf_r0flash/</code> 


===== 9. Prepare a brand new r0ket =====
See [[build|main Build article (scoll to the bottom)]],
or:

Bring the r0ket into ISP-Mode:
e.g. by using Method 1 (up to 30 seconds, but works always)
  * Power off r0ket
  * Press and hold button “Left”, power r0ket on
  * Connect r0ket via USB

If you want to start from scratch:
<code>
rm /Volumes/CRP2\ ENABLD/*
</code>

Install the "initial" formatting firmware:
<code>
cd firmware
make APP=initial
cp firmware.bin /Volumes/CRP\ DISABLD/firmware.bin
</code>
The Data Flash will be formatted.
Now the r0ket will present a flash file system called "NO NAME" over USB. 
Install the l0dables:
<code>
cd l0dable
make
cp *.c0d /Volumes/NO\ NAME/
cp *.int /Volumes/NO\ NAME/
cp *.nik /Volumes/NO\ NAME/
cd ..
</code>
Now install the Camp firmware ("final"):
<code>
make APP=final
cp firmware.bin /Volumes/CRP2\ ENABLD/firmware.bin
</code>

=== Example commands that worked for me ===
MacOSX, Lion, Up-to-date MacPorts - DanBUK
<code>
sudo port sync
sudo port install arm-none-eabi-gcc
git clone git://github.com/r0ket/r0ket.git
cd r0ket
git checkout c583ddc7e3b6ecc2cdb94fe0a0474d52bcbb220b
cd firmware
cp SECRETS SECRETS.release
# Edit SECRETS.release
./release-all
make APP=initial
cp firmware.bin ../release/initial.bin
cd ../release/
# ISP Mode - Power on whilst holding left on Joypad
# NB. This isn't always CRP DISABLED, could be CRP2 ENABLED
mount | grep "CRP DISABLD"
# /dev/disk3      32Ki   32Ki    0Bi   100%    /Volumes/CRP DISABLD
cp initial.bin /Volumes/CRP\ DISABLD/firmware.bin
diskutil unmount "CRP DISABLD"
# power off
# power on
mount | grep "NO NAME"
# /dev/disk3 on /Volumes/NO NAME (msdos, local, nodev, nosuid, noowners)
# If you want to start completely empty:
# rm -Rf /Volumes/NO\ NAME/*
cp files/* /Volumes/NO\ NAME/
diskutil unmount "NO NAME"
# press button (joypad middle)
mount | grep "CRP2 ENABLD"
# /dev/disk3 on /Volumes/CRP2 ENABLD (msdos, local, nodev, nosuid, noowners)
cp final.bin /Volumes/CRP2\ ENABLD/firmware.bin
diskutil eject "CRP2 ENABLD"
# power off
# power on
# Enjoy!
