h2sammo Wrote:is there a way to select what crystalhd driver or xbmc revision i use? from reading in the xbmc forums and from reading http://code.google.com/p/crystalhd-for-osx/updates/list it seems as if the latest crystalhd driver revision uses 16 DMA when it has been shown that 8 DMA works best for the low mem atv has.

also, i read in the forums davilla advises crystalhd revision 156 for xbmc 10.1 when using the first generation BCM video decoder (like I am).

fodos Wrote:You are right Sam, but not that is the problem. I have 24 (23,976) FPS and 25 FPS videos. The best setting to playback smoothly all would be the "automatic refresh rate change to the video fps", I think that is what you said. But in that setting, when the system tries change the refresh rate, the system crashes often (not all time). The effect is the same when I try to change the refresh rate manualy.
Do you think it is a configuration problem?

bass63 Wrote:It is a known bug of HDMI handshake with ancient nVidia drivers used in the image. You can update them, but you will loose HDMI audio (not working in other versions). I got this bug WITH EVERY TV I OWN (Sharp, Samsung and Panasonic)

I use this command to update drivers and can confirm they're working fine (though it's not latest version)

ps aux|grep -v grep|grep -i xbmc.bin|awk '{print $2}'|xargs kill -9
sudo wget http://us.download.nvidia.com/XFree86/Linux-x86/256.25/NVIDIA-Linux-x86-256.25.run
sudo sh NVIDIA-Linux-x86-256.25.run

People also suggest changing modes in xorg.conf, but I couldn't figure it out.

But there's a quick and dirty temporary solution to a problem - just turn your TV off and on, or replug HDMI cable every time you got that black screen. Changing inputs works too on some TVs. System is not crashing, just freezing when changing refresh rates.

bass63 Wrote:OK, just tried a new image.
First thing - exit and restart DO NOT WORK. System hangs or shutting down. Can I somehow fix it myself, Sam? Thanks!

ajayrockrock Wrote:I just hacked up the /home/atv/scripts/crystalUpdater.sh script and made "downgradeCrystal.sh". All it does is checkout revision 170 from the trunk instead of the release version. You should also disable the updates so it the driver doesn't get upgraded the next time you reboot.

NOTE: I just did this and ran it in the hopes that it solves my crashing issues. (it didn't, the search goes on...)

Code:

#!/bin/bash
#get current SVN tag if updating
CurrTag=trunk
echo Checking out latest tag
mkdir chd
cd chd
svn checkout -r 170 http://crystalhd-for-osx.googlecode.com/svn/"$CurrTag"
echo Compiling lib
cd "$CurrTag"/crystalhd/linux_lib/libcrystalhd
make
sudo make install
echo Compiling driver
cd ../../driver/linux
autoconf
./configure
make
sudo make install
sudo modprobe crystalhd
cd /home/atv
echo Cleaning up directory
sudo rm -rf /home/atv/scripts/chd

pmcd Wrote:Hmm... this doesn't seem to be working out. I have tried several times with different media. I plug the usb hd (sdc) in a hub along with the bootable flash drive (sdb) created by the script. The ATV boots, updates happen on the sdb flash drive but the sdc drive (the hard drive I eventually want to boot the ATV) isn't touched. The flash drive boots the ATV just fine and XBMC has been updated and everything works great. But it doesn't seem to be restoring to the sdc drive.

For me this fixed the problem.

Sam.Nazarko Wrote:Not sure updating drivers will fix the problem.

bass63 Wrote:It does. I have 2 AppleTVs and 3 TV-sets - all the last year models from different vendors. That refresh rate change bug exists on EVERY installation with EVERY image (even first one) on EVERY TV i own. Updating drivers fixes the bug.

I'm really curious, Sam what kind of TV or connection you're using?

And by the way - you keep refering to the "manual" in your posts, but it is almost impossible to find it - you doesn't include it in readme.txt, you have no links to it in your blog and I had to google really hard to find it using your quotes as references Just post the link to it somewhere, it may reduce volume of questions that already has been answered.

Sam.Nazarko Wrote:No. That won't work, sorry. You need to make sure that /dev/sda is the device you want to image and /dev/sdb is source. But why you are doing it this way I don't know? Just restore to the USB HDD within the Installer directly rather than going Installer > Flash Drive > USB HDD

Hope this clears stuff up

pmcd Wrote:Sorry to be picky here, but if you do Installer--> USB HDD you end up with a 4 gig hard drive which does not occupy the whole drive ( unless one manually uses parted, etc... and that does work fine). What I am saying is that installer-->USB HDD processes a 4 gig hard drive which works perfectly well but the expansion to the whole drive doesn't happen automatically.
