R89-Hardware/Thermal/case issue feedback here

[Arbelzapf]

There are solder points for an unused USB port to the left of the microphone at the front of the board. Feel free to solder a cable on and connect a webcam. Only needs a whole in the case.

I wasn't aware this was a microphone, I assumed it to be the IR receiver. Nice!

I wondered if that USB port is active, maybe oman could tell.

Downloaded Vega S89 Profile to my Harmony Remote , IR reception is terrible !

Due to interesting design of the Top Casing IR LED blocked almost 60-70% !!!

Board should be mounted Lower if possible or a Bigger IR Window is essential...

TBH I don't like the Casing at all cos back I/O part also is very problematic , its quite hard to insert HDMI cable etc.

Harmony has the S89 in their data base? I used the learning mode to teach each button from my Tronsmart S89H remote to my Harmony remote.

Yes !

They probably get that from your profile if you've synched your remote

I can confirm that. The spdif cable is not "in" all the way too due to the design.

Yep just needed some trimming that flap surprised this was missed.

... but the kernel doesn't determine the CPU temperature... always at 2°C... a really cool device...

Yep the most thermally stable android box/chipset ive tested.

which kind of cable or which way do you use to connect to this really small tiny spots at back of the pcb?

[ATTACH=CONFIG]7726[/ATTACH]

The temperature can show by

cat /sys/class/hwmon/hwmon1/device/temp0_input

I test it running CPU Prime Benchmark,after several mins,then:

root@rk3288:/ # cat /sys/class/hwmon/hwmon1/device/temp0_input
cat /sys/class/hwmon/hwmon1/device/temp0_input
102

But still running...

Maybe it seams so, this kernel/SoC also know thermal throttling?
Because after ~15 minutes at 100% cpu usage, it begins to throttle, BUT we talk about "after ~15 minutes" and not about ~1 minute like the s802 AND not so often happens (also not after one more 10 minutes)
Unbelievable!

The case, especially at the bottom, gets really warm/hot.
At the middle of the second picture you can see what ?maybe? happens if I lift a little bit up the case: less thermal throttling
So I think you really should use more space to the surface (I place the box at a glass table)...

BTW:
At my stress tests at s802 (http://www.freaktab.com/showthread.p...-Test-Scenario) I had the problem, if I switch between the apps, they may crash (e.g. 'StabilityTest (ROOT optional)' => classic test) or reset the GUI (e.g. 'System Tuner Pro' => monitoring) so I have to know how to handle it (at which moment switch to which app)...
BUT not at the RK3288 (ok, the curves may pause BUT no crashes)...

Tom,could you do the Stress test Scenario for R89?

[oman]

For in case you are not aware of this feature. After opening the unit (only the two Philips screws at the back) I noticed the microphone in the cover. So I tested it with Ask Google, Sound recording and Skype, and it works nice and clear. Now just to populate the camera sensor that could go with it.

Just have the camera connector populated on it...but no place to hold it for the camera on the case.

I wondered if that USB port is active, maybe oman could tell.

Yes ,it's alive...but there are 3 usb ports already.

Okey,so the back IO is a little hard to insert...but if you connect to success,just leave it...We'll take care about it.THX.

It's a UART2USB device to connect to PC for debug message..

I could, but why should I?

I have done it for ~2 hour and everything is fine (instead of the s802 ) and the result is the same as my quick shot I had posted, so I have no idea what I should write instead of "Unbelievable!"

OK, I will see what I can do

Yes, of cause something like 'CP210x' or 'PL2303', but my question was "how" and "which kind of really thin cable" to solder at it
