Heat Sink ? I remember lots of discussions and trials on the now-defunct slice forum and in this forum
as chewitt says it needs a bit of work and the CM3+ will need a slightly thinner heatsink (fatter CPU because of the silver top). The easy solution is as chewitt suggests, get a stick-on one. I found that it still did not really remove enough heat, especially when playing video, so I adopted the DIY approach. While the measurement of the sink needs to be fairly accurate, there is a slight bit of "give" if you press on the CPU so there is a small amount of lattitude when making one.
There were a lot of different designs using bits of copper, I recall one was using buss-bar from a consumer distribution unit.
I used a copper core from an old PC CPU cooler and while not the best at heat transfer, using an aluminium plate, fixing it to the case with epoxy resin glue and letting it sit on the CPU with some heatsink compound works fine. The combination of Cu and Al gave "just the right" size to bridge the gap. The plate is fixed so it prevents the sink being dislodged and doing damage inside.
I attach a picture of the parts. The kaptan tape was used to position the sink and the heatsink compound was used to check contact with the CPU before finalising the design. You can use heatsink compound to help measure the gap, when it transfers to the case or CPU you have it "just right".
I hope that gives you an idea of how to do it.
(LE9 Beta 3) 8.95.003 builds (Kodi18 RC5.2) are ready for testing, could you pls test if it starts/works (we are sadly low at slice hw so we can't properly test it)
CvH : I tested CM3, it still works fine. Also confirm the updating / changing of the password works fine and is remembered across updates Music (mostly flac) only Slice
Is it worth upgrading to CM3 for audio only use?
I used the CM1 for audio and it worked fine.
I upgraded to CM3 and the GUI interface and general responsiveness is much better. Worth the effort, I think, as the user experience is much smoother and faster, with less jerky screen / pointer movement. However the CM3 really needs a bit of cooling and a number of folks have "stuck a lump of copper"*** between the CM3 CPU and the case which keeps it running much cooler. Less of an issue for audio, almost mandatory for video.
If the sluggish user interface (compared with a CM3) is not an issue, I agree with chewitt If it is not broken, don't fix it.
*** Technical term, the actual solution was, in most cases, a little more refined (pun intended)
LE9 Beta 2) 8.95.002 builds (Kodi18 RC4) are ready for testing, could you pls test if it starts/works (we are sadly low at slice hw so we can't properly test it)
Index of /test/slice/
Loaded fine on my slice and seems to work fine on the headless music player using VNC as the remote screen.
Also loaded on the main media player Slice with HDMI screen, video and music play as expected.
On Beta 8.95.001 I am using the Confluence skin. I went back to Estuary to test colour change. It works fine and survives a reboot. I selected green first, then rebooted and selected another, having seen the green come back OK. All seems to be fine on my Slice.
Maybe, just maybe it is just you, however, my test on its own, is a statistically insignificant sample
(LE9 Beta 1) 8.95.001 builds (Kodi18 RC3) are ready for testing, could you pls test if it starts/works (we are sadly low at slice hw so we can't properly test it)
Tested 8.95.001 on the Slice
I use it head-less with VNC for music. That works fine (after I updated the add-on Turned auto update for the add-on on!)
Downloaded Confluence skin, both that and Estuary seem to work fine in a short test.
I will use this build now for more extensive testing on the Slice
Thanks for all the hard work
I did an update with a PI3+ and IQAudio board.
Then I could select IQ audio output and it all "just works" on the 8.95.001 beta.
BTW I regression tested the VNC issue I reported a while ago, and that still works too
Looking good so far
Thanks for the fix, I confirm it works fine on a Pi3+. When there is a build for Slice CM3 I can test that too.
Meanwhile I will give the Pi3+ a longer test
updates and boots fine.
Mouse and keyboard work fine with multimedia kbd/mouse
I use UltraVNC as the GUI as the Slice is headless. My computer keyboard works fine. The mouse does not work. The pointer appears at the last place it was left using the multimedia keyboard / mouse. The ultraVNC mouse pointer appears when mouse button clicked and then goes away after a short while.
If no mouse has been connected to the Slice since boot, the mouse pointer is at top left. It appears on mouse click and goes after a short while.
removing the dongle for the MM keyboard and rebooting Slice and the bug is still there.
Reverted to previous release version.
Slice using CM3
The same problem exists on V8.9.008 and V8.9.009 on a Pi 3+ with IQ audio.
VNC mouse pointer is not working but mouse works fine when direct attached.
8.90.009 boots fine and plays an internet stream fine.
I use UltraVNC as the screen GUI interface. The mouse does not work via VNC. Moving mouse sometimes makes a big pointer appear in the top left corner
Thanks chewitt, happy to remain on 8.2.3, just wondered why there was a difference in release number between Pi and Slice. Thanks also for the heads-up on new builds .
Is there an update from 8.2.3 to 8.2.5 for the Slice after the problems with 8.2.4 and 8.2.5 were reported? The download page still offers 8.2.3 for Slice but my Pi boxes have 8.2.5 on them.
Do you get anything at all for Fast Rewind? I don't.
Happy to help, bit too wet in the garden at present, and this is a pleasant diversion from what I should be doing inside
I confirm I do not see a Fast Rewind either, function OK no LED pattern on both my Slice3 units. I wonder if the pattern file has the wrong name? Chewitt??
After a power off reset on my main box, everything seems to work as it should (fast rewind excepted).
chewitt : I notice that the power off sequence on the other Slice3 (main box) is a little different, it only does the sequence once quite fast and never gets to the end before the power drops. They have different HDDs in them, the main box (a full fat Slice, gunmetal) has a standard issue HDD (Toshiba, I think). The Slice Lite has a Western Digital HDD. Maybe this is the reason for the different pattern?
On my Slice, I occasionally get a whitish flash of the LEDs at shutdown, not long red/Orange like it should be.
bleep42 we kind of "crossed in the post"
I will go and test on my main box, and see if the problem exists without doing the clean install... I would rather the upgrade process worked. I cannot recall if I have done a power off reset on that box as I just did the update remotely dumping the .tar with SCP and rebooting.
Let you know....
DownloadedSlice3.arm-8.1.0.image.gz from downloads page (rather than using the image from last time)
reloaded to eMMC, booted and re-scanned music files. I have enabled SSH and am running PuTTY and TOP to see what is going on, as in the previous test.
Try playing audio with default interface (HDMI) plays OK according to the screens but not tested audio.
Set audio to ALSA. Play music and LEDs seem OK during play, pause and stop. Once the single green LED came on after the end of the play sequence and then went out a second or so later.
REBOOT: the LED sequence stops at the end of the lines and restarts.
During the power up sequence (and I thought I saw it before in the previous test) there are random red / green white flashes, while the expected blues etc are being displayed.
Rebooted and tested again, same thing with the startup LEDS, random not normal colours.
POWER OFF and remove power plug (this is important, I think......)
..... and everything seems to work as it should.... I am assuming that the power off LED sequence works but restarts some way through is a "bug" as the shutdown.png is a single decreasing line of red / yellow LEDS, but it really does not matter. The important thing is that it shows the pattern as an indicator of power off state.
The moral is: load a new version and then do a power off reset of the box and all will be OK.... possibly.
Be interesting to see if bleep42 finds the same.
Any thoughts / observations / other tests you would like done?
For kicks (and if you don't mind) .. make a backup and move off-box; then clean install to the eMMC again
I did not mind and I have done a reflash of eMMC and reloaded 8.1.0. I used the Libreelec USB SD creator for windows to download the SLICE3 image and then copy it to the Slice. Added music library (000's of FLAC files)
All appeared OK at first, default sound was HDMI (did not test sound output) but asked it to play, pause and stop. LEDs seemed correct. asked it to power off and the red/yellow sequence was kind of OK but stopped and restarted several times and the power on again was fine (blue leds).
Changed audio to Pi analog LEDS nearest power socket came on (two one blue and one green): unexpected!! No audio (expected).
Changed to ALSA Default(snd_slice Analogue) and got sound (expected) .
play music, green leds flash at start of track, all go out and a short while later the LED nearest the power socket comes on and remains on (green). Next track starts and green LED sequence is normal, all go out and a short time later the single LED (green) comes back on again.
Reboot, the red / yellow LEDs have several attempts at the sequence (get to the corner) pause, restart sequence and proceed to end.
Play music, LED green sequence plays at start of track.... no green LED on after. Next track starts and sequence of green OK and no green LED on after.
reboot and the power off sequence is OK but for the half sequence and then the whole sequence on power down
power off and remove power then restart. The sequence at power off is slightly different from reboot in behaviour: it pauses for a little longer just before the corner is reached then restarts and completes normally. At this time the hard disk is making a noise (powering off, perhaps?)
Reboot and it is fine, all seems to work normally.
What is different: no TV headend42, VNC, openweathermap and no playlists.
All a bit strange!
I will "rinse and repeat" and report back
