Incomplete list of what works and what not

Unread post by joerg » Tue Mar 12, 2019 11:19 pm

V28 from Mar/08/2019
Works:
- Play audio files via 3.5mm connector. Sounds nice, no disturbances.

- Update via Odroid settings from official server yes. From mirror server not, but I am not sure if I waited long enough.

- /dev/gpiomem is there and works with wiringPi


Don't work / missing:
- SuperSu app missing. Need to install Magisk to have root app.

- Adb shell always disconnect:

Code: Select all

- No cifs support, mount -t cifs ...: No such device. Would be nice to have, if you want to mount a music folder from your NAS ... Can confirm after compiling cifs.ko, md4.ko and nls_utf8.ko I can mount: busybox mount -r -o noperm,rw,file_mode=777,dir_mode=777,uid=1023,gid=1023,username=xxxxxx,password=xxxxxx -t cifs //192.168.1.15/RnB /data/media/0/cifs/RnB and have access to it with PowerAmp.

- Add account: Email keeps stopping. Some apps loke PowerAmp need for verification.

- VU7 touch functional only with otg port, not with usb3 ports

- no iec958 audio signal at J7. But I am prepared...

What update about following?
a) Any ghost CPU load issue as reported in linux?
b) USB Webcam functionality?
c) HDMI CEC support?

@joerg, thank you for the detail and appreciate all your contributions.

1. SuperSu is not working on Pi yet, so it's not included in the image. And we are looking into another app or workaround to replace SuperSu.
2. We have not figured out the problem of ADB problem why USB is not stable.
3. I think MTP should be working, but let us check it again.
4. CIFS is not enabled in the kernel, that will be included in the next release.
5. Account - not sure what's the problem, would need to investigate if it's Android problem or GApps problem.
6. VU7 would work on USB3 ports, but let us try it out again.

@kafan1986,
1. We have not looked into this yet, could you share the reference link what you are considering of?
2. Looking into USB webcam support, a preview is working but capture is not supporting yet.
3. CEC has been tested with Samsung/LG TVs.

@tobetter, my VU7+ is one from the first release. It has the problem that the cable must be reconnected to make touch work. I have another from the second release, but I can't try it, it is in production.

Oh, I see. Let us check it again. USB ports are on at the power cycle and never off through a full boot cycle. One thing what I am guessing is that USB port can be controlled to turn on and off by a command line so that you don't need to reconnect the cable. I would try this soon.

Tapatalk wishes you to have fun with ODROID.

@joerg, our VU7+ (recent version) is working and no chance to test the first release, we do not have it. :)

Hi, joerg.
Turn off USB debugging in developer options for MTP.

-> I tried to add account by the Email and I did it. But to add account, I should check less secure app access on my google account. :)
