Support for Botic Linux driver

So, it appears there is no busy device or resources other than mpd. How do you think, miero?

I checked my working Botic system in the same way.

Code:

root@botic:~# lsof | grep snd
mpd       1194             mpd  mem       REG      179,2     289448       9583 /usr/lib/arm-linux-gnueabihf/libsndfile.so.1.0.25

mpd       1194 1323        mpd  mem       REG      179,2     289448       9583 /usr/lib/arm-linux-gnueabihf/libsndfile.so.1.0.25
mpd       1194 1323        mpd   15u      CHR      116,3        0t0       8415 /dev/snd/pcmC0D0p
mpd       1194 1324        mpd  mem       REG      179,2     289448       9583 /usr/lib/arm-linux-gnueabihf/libsndfile.so.1.0.25
mpd       1194 1324        mpd   15u      CHR      116,3        0t0       8415 /dev/snd/pcmC0D0p
mpd       1194 1325        mpd  mem       REG      179,2     289448       9583 /usr/lib/arm-linux-gnueabihf/libsndfile.so.1.0.25
mpd       1194 1325        mpd   15u      CHR      116,3        0t0       8415 /dev/snd/pcmC0D0p
mpd       1194 1326        mpd  mem       REG      179,2     289448       9583 /usr/lib/arm-linux-gnueabihf/libsndfile.so.1.0.25
mpd       1194 1326        mpd   15u      CHR      116,3        0t0       8415 /dev/snd/pcmC0D0p

Ignoring the rows including CHR, which is basically set for real-time attributes for the process by chrt, I don't see any difference from the ichiban's result: that means your basic setting appears almost correct.

Though I'm not sure if incidental alteration of file system permission can cause this error, ichiban, could you show your /data/remote contents by the command below?

Code:

ls -ld /data/remote/*

Also, for setting of /etc/fstab, you might try those options.

Code:

//remote_IP_address/top_dir_of_your_music_source  /data/remote cifs  username=your_name,password=your_password,uid=mpd,file_mode=0777,dir_mode=0777,iocharset=utf8,rsize=16384,wsize=4096,cache=strict,sec=ntlmv2  0 0

If things remain unchanged, I'll strongly recommend to go back to the start and try to prepare a bootable Botic SD on linux using such a live CD/USB as miero recommended somewhere before. This will be more efficient than working on Windows. I think you had wasted your time so much enough to learn linux.

I'm waiting for a response on the Hermes-BBB/Botic cape for BeagleBone Black thread regarding the J1 connector to the BBB T5-6-7-8 pins.
I when I assembled the boards I thought the four pin connector was for the battery, for which I'm waiting. But, going back and looking at some pics of other builds I see it's not for the battery. Could this be the source of my problem.

Duffy Moon · 2015-05-14 4:00 pm

It is for the battery - indirectly. I guess it conveys power to/from the battery.

Oh well, you have dirs of wrong permission. The dir /data/remote, for exampe, should be like this:

drwxrwxrwx 2 mpd root 0 Jul 6 2014 /data/remote

The owner of /data/remote should be mpd. That is to say, this Mr "root" has been occupying your music source directory, saying to Mr "mpd", "Don't come close to me." That's why Mr "mpd" could not transfer your music source to Hermes-Cronus via Botic BBB.

Well, it's time to change the owner and permission. You might try this one:

chmod 777 /data/remote
chmod 777 /data/remote/*
chown -R mpd.root /data/remote
chown -R mpd.root /data/remote/*

I hope this will work.

BTW, J1 issue is not related to your current problem. Soldering 4 pins can be done anytime later.

Permission denied on these commands. I'll delete the directory and recreate it.

Okay, it should be Windows resisting to permission change. Go to the source files on Windows and make them all accessible to guest or whatever it is.

Hope this will work.

I'm wondering how people are playing SACDs. Also, if anyone know a way to get HLS streams working, I'd love to hear it.

you do not need write access "w" for playing the file...

ichiban, you can try copying any file from remote into /tmp directory and play it there

That doesn't work. I think twluke is right --

nope, he is not.

busy is the audio device (Botic) not the file which you want to play...

and I really have no idea what could be wrong in your case ....

I'm considering option inspecting it by myself, but you would need to allow me to connect on your BBB. If you agree please write me a PM, I will send you instructions (later).

You are most kind.

But, first maybe I should see what happens by redoing the flash to basic debian then onto botic v4 ~ v5 ??? Yes?

Yes, changing owner is the first thing to do. Changing permission is next.

ichiban, please post here output of following command before deleting image:

for i in /sys/module/snd_soc_botic/parameters/*; do echo "* $i"; cat $i; done

I believe there is something misconfigured. It is not issue of permissions as twluke implies, not in this case.

I have nuked it back to basic linux. Will execute the instructions as appended below................

ichiban · 2015-05-14 9:25 pm

Got to this step and cannot recall how I upgraded kernel on SD card to botic5

========== from ieee.com =========
Flashing image on eMMC

The eMMC of BBB can be flashed with this "Botic distribution" using following

steps:
Notice: please upgrade kernel on SD card to botic5 and reboot before flashing
to eMMC

(( backup all important ))
(( boot from SD card ))

root@bbb:~# umount /boot/uboot/
root@bbb:~# /opt/scripts/tools/eMMC/generic-eMMC-flasher-12mb.sh
... (after 5 minutes of copying data)

root@bbb:~# poweroff

((wait until it powers down))
((remove SD card))
((power it on))
