Waveshare 7" IPS display already support?

hondagx35 wrote:Hi all,

here are some notes to the ODROID C2 image.

- it is a first test image
- image runs in dev mode (maybe a little bit slower)
- Spotify does not work, because there is no 64 library available.
- the filesystem is read only (ro)*
- support for IR remote is implemented**
- native DSD via USB is implemented
- local browser optimized for ODROID VU7 (7inch 800x480 HDMI display) is implemented (MENU->Settings->Local browser)
- lyrics by hovering over album art (can be disabled in database "redis-cli set lyric 0")
- mpd-watchdog is enabled by default, this can be especially useful when playing internet streams.
- I2S support for ODROID HiFi shield (MENU->Settings->I²S kernel modules)

*
The image runs with the filesystem mounted as read only.
Sudden power loss, unproper shutdown or pulling the plug can't damage the filesystem anymore.
This also will extend the lifetime of your sd card, because typical flash memory can only tolerate limited number of write cycles without being worn out.
The only thing you have to consider is:
All changes (add network shares, updating mpd library ....) will be discarded when cutting power without proper shutdown.

The file system can be made temporarily read write on the console:
Code: Select all
root@runeaudio(ro):/#
root@runeaudio(ro):/# set_rw
root@runeaudio(rw):/#
root@runeaudio(rw):/# set_ro
root@runeaudio(ro):/#


**
Lirc is activated by default and configured for the ODROID IR Remote Controller.
The configuration files are in "/etc/lirc" and have to be adapted for other remotes.
With the ODROID remote you can power down or reboot the device by holding the power button for more than 5 seconds.

PS: As usual, sorry for my bad english.

Downloaded again, wrote to micro SD again, played again, result as follows:

- no sound at all from HDMI when selecting in MPD "ODROID C2 HDMI"
- in MPD selected x-Core USB 2.0 (same as the case of Pi 2 played perfectly up to DSD128) sounds clicked, pop, noisy when connected to USB DAC SMSL M8

@hondagx35: the file you uploaded is the fixed bugs, latest one to date? ;)

@smallfat: have you tried it?

@hondagx35: I logged in as ROOT to run ssh 'alsamixer' command that I have following info:

It seems the Rune lack of sound out to HDMI. My M8 USB DAC is there, even the sound control (default as I saw in the case of Pi 2) is not there.

Hi All
I have tested the image and reinstalled image again but same problem in my system. The problem is playing the song around 5 second (sometime 10 or 12 second) that the system stop it and then it will repeat this song automatically again 5 second...again 5 second...again 5 second...again 5 second...so i can't listen the song completely. I am using the Audiobyte Hydra Z USB to connected the C2 (Pi 2 played perfectly) and wired network.

My English is not good I hope they understand of my issue. Thanks!

All ODROID sound driver (HDMI and HiFi shield) do not expose any mixer controls!
So your alsamixer output (HDMI) is the expected one.

I'm sorry, but don't ask me about all these USB DAC stuff.
I do not own USB DACs except 3 really cheap ones.
Please post your questions / issues on the ODROID forum.

BTW:
And no, i will not ask for the debug data again and again!

I got the same problem as Elvis Mok. The song play for few second, and then it will replay from the beginning of the song again. Tried both network and USB storage but also got the same problem.....
Same problem occurred on 44.1 / 96kHz /dsd file
Also tried to change both Audio Buffer Size and Buffer before play, but not able to solve the problem.

Hi Elvis Mok, Hi acml,

Could you please help. Thanks!

For sure i could.

But without the needed info (debug data, used hardware ...) you also can ask your grandma for help.

Re: ODROID C2 -> NFS access

Postby captainkremmen » 19 May 2016, 20:29

Hi
Sorry very new to this...but I hope this is a simple question.
When I choose NFS for the mount (a Synology drive) it does not let me enter a password / username. Only guest access?

ADDED, from systemctl:

"rpc-statd.service loaded failed failed NFS status monitor for NFSv"

Thanks
