XBMC CrystalHD Update #2 August 2010

To leverage crystalhd kext, library and firmware based on r156 (http://code.google.com/p/crystalhd-for-osx/updates/list), replace Step 2 in the post

http://todayguesswhat.blogspot.com/2010/08/xbmc-crystalhd-updated-instructions.html

with the following:

# Step 2: Obtain the crystalhd kext, driver, and firmware and install in to the appropriate location

# run as root (sudo -s)

cd /tmp

rm -rf crystalhd-for-osx-3.6.0*

wget http://crystalhd-for-osx.googlecode.com/files/crystalhd-for-osx-3.6.0.zip

unzip crystalhd-for-osx-3.6.0.zip crystalhd-for-osx-3.6.0/*

rm -rf /System/Library/Extensions/BroadcomCrystalHD.kext

mv crystalhd-for-osx-3.6.0/BroadcomCrystalHD.kext /System/Library/Extensions

chown -R root:wheel /System/Library/Extensions/BroadcomCrystalHD.kext

chmod -R 755 /System/Library/Extensions/BroadcomCrystalHD.kext

rm -rf /usr/lib/libcrystalhd.dylib

mv crystalhd-for-osx-3.6.0/libcrystalhd.dylib /usr/lib/

chmod 755 /usr/lib/libcrystalhd.dylib
chown root:wheel /usr/lib/libcrystalhd.dylib

rm -rf /usr/lib/bcm7001*fw.bin

mv crystalhd-for-osx-3.6.0/bcm7001*fw.bin /usr/lib/

chmod 644 /usr/lib/bcm7001*fw.bin
chown root:wheel /usr/lib/bcm7001*fw.bin

rm -rf /tmp/crystalhd-for-osx-3.6.0
rm -rf /tmp/crystalhd-for-osx-3.6.0.zip

# reboot

# check that crystalhd driver is loaded :-
kextstat | grep crystalhd

Output :-

XBMC CrystalHD Updated Instructions using 2.01 driver – August 2010

There are plenty of simpler ways to install/verify Crystal HD on the Apple TV.   Below steps should work if you like to get your hands dirty :-

(note – cut/paste blocks of colored text as a whole)

# Step 1: SSH in to the apple tv as the user frontrow using your favourite ssh client

# having successfully logged in, switch to the root user
sudo -s

# Note! - you will need to manually supply the ROOT password for the ABOVE command before proceeding ...

# Step 2: Obtain the crystalhd kext, driver, and firmware and install in to the appropriate location

(Note, see the following post for a replacement ‘Step 2’ http://todayguesswhat.blogspot.com/2010/08/xbmc-crystalhd-update-2-august-2010.html if you want to run a newer build based on r156 http://code.google.com/p/crystalhd-for-osx/updates/list)

cd /tmp

rm -rf crystalhd-for-osx-2.0.1*

wget http://crystalhd-for-osx.googlecode.com/files/crystalhd-for-osx-2.0.1.zip

unzip crystalhd-for-osx-2.0.1.zip crystalhd-for-osx-2.0.1/*

# Step 3: to load kexts, we require Turbo's ATV or Kext enabler ...

# check for presence of /sbin/turbo_atv_enabler.bin or /sbin/turbo_kext_enabler.bin

# Step 4: Ensure that the crystalhd kext is activated at boot time !!EITHER!! by adding a new startup item under /System/Library/StartupItems or adding an entry to /etc/rc.local ; If you have installed the Crystal HD driver in the past, it is worthwhile having a quick look on disk to see which mechanism is currently being used to load the driver and continue leveraging that approach.

# Use either method 1 or method 2  below ...

# Step 4 - Method 1:
# Rather than put the kextload entry in /etc/rc.local (as in method 2) - below we make use of /System/Library/StartupItems

# Step 6: From the Apple TV User Interface, Go to the launcher menu, then choose "Settings", then choose "Downloads"
# - Obtain the latest xbmc download build available


# Step 7: Reboot the Apple TV ...
sudo -s
reboot

# Step 8: After the Apple TV has rebooted, fire up XBMC from the launcher
# check that XBMC has detected the Crystal HD ...

# Check under "System -> Video -> Playback -> there is an option selected "Allow hardware acceleration (CrystalHD)"

# If no /usr/lib/libcrystalhd.dylib or no BroadcomCrystalHD.kext loaded, then CrystalHD will NOT show up above..

# Optional - Basic debugging can be done in the event the Cyrstal HD was not detected:

# switch to root
sudo -s

# check that crystal hd hardware was detected
