[beagleboard] Re: Micro SD image ran out of space

[blues man]

Here's another tip that may help others.  For some reason that I don't 
know, my uSD cards have "shrunk" in capacity after burning images for my 
'bone - they show as a fraction of their rated storage.  This is easy to 
fix with a free download called SD Formatter 
 from the SD Association 
(recommended by Sandisk).  HERE 

 
are the instructions, and it's worked fine for me each time I've needed 
it.  I use Robert's method to expand the file system on all my Beaglebone's 
uSD cards - there's a 64 in there now.

Re: [beagleboard] How to change color bit depth

[blues man]

So the reason I could use JRMC before was that I ran headless and 
configured it via TightVNC - I never had a monitor connected to the 'bone.  
I'll go back to that approach - thanks!!

[beagleboard] How to change color bit depth

[blues man]

I followed the advice generously offered by others here, expanded the file 
system to the full 64G on my uSD card, burned a fresh Debian Jessie image 
from BB.org, and am now running nicely from the card.  So I reinstalled 
JRiver Media Center 21 (which I love and have running on multiple other 
machines - including a Pi 3 - and had running on my 'bone during their 
development & beta period for Linux on ARM), expecting everything to be 
fine - but the JRMC window is just a white rectangle.  The advice I got 
from the JRiver tech staff was that the color bit depth on my BBB is 
probably set to 16 (which turned out to be correct) and has to be set to 24 
for JRMC to display properly.  So I edited /etc/X11/xorg.conf to change the 
bit depth from 16 to 24 in the display section, and I couldn't reboot 
afterward. I got everything back to the above state again but changing the 
display section in the xorg.conf file from 16 to 24 again prevented booting 
and I had to restore the original intact image to get it running.  And I 
cannot find any other configuration file with a color bit depth setting in 
it.

This has happened to others - there are several posts on various boards 
about it.  But no one has posted a solution anywhere else.  Does any of you 
have an idea how I can get my display up to 24 bits?  Thanks!!

David

Re: [beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

Except when I'm experimenting with it for fun, my 'bone is used only to 
play music. I ran it headless when I was using MPD, but there are a lot of 
cautionary posts on the appropriate forums about having a monitor connected 
when booting JRiver Media Center - so I planned to leave an HDMI cable 
connected to one of the inputs on the nearest monitor but never use it (I 
access the program via JRemote on handhelds).  However.I've not tried 
using JRMC headless myself, and there seem to be many people doing this 
without difficulty.

 I won't access my network via WiFi because USB is the only way for the 
music to get to the DAC, and sound quality can suffer when files are being 
brought in and out via the same USB.  So I use eth0 to access my FLACs on 
NAS and leave wlan0 disabled.

I think using the card with an expanded file system sounds like the best 
bet for me - I won't suffer serious emotional trauma from having to abandon 
my quest to use the MMC. :)

Re: [beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

Thanks, Graham!  I'll just use my 64G uSD card, expand the file system, and 
go back to JRMC on Debian.  I guess the older images didn't fill the eMMC, 
so I still had room for JRMC - but the latest one tipped the scale too 
far.  I've been viewing having to run from the card as a sign of defeat, 
for some odd reason! :)

Re: [beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

Thanks, Graham. I thought that holding the boot button down until the leds 
light does flash the MMC and that the flasher image was instead of holding the 
button while powering up. I'm using 32 & 64 cards, but I didn't expand the 
memory partition on either one. I'll just do that and run from the 64.

Thanks & best regards-

David

It installs and runs fine - I just can't then install JRiver Media Center, 
apparently because of the "no more space on device" problem.

Re: [beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

That answers one big question - thanks!  Then there must be something wrong 
with my 'bone, because it's not removing everything now when I reflash. I 
didn't have this problem through multiple installations and reinstallations 
of JRiver and other similarly sized packages, so something has changed.  If 
I can't figure out what it is and fix it, I'll just have to buy a new board 
to use as a JRiver zone. 

I got over 2 years of great fun and education from this one, and I believe 
the new version has a better processor anyway - so I'll just bite the 
bullet and buyr a replacement.  Any last ditch effort tips that might help 
me fix this one are greatly appreciated - otherwise, I'll leave MPD on it 
(since it still works) and use it as a music player on the patio. It 
doesn't owe me anything, and it deserves a peaceful retirement. :)

Re: [beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

Thanks.  I'm happy with the currently released image - I don't want or need 
to go back to the original OS version. But just reflashing the eMMC doesn't 
seem to clear out all the cobwebs, as there's clearly less memory now than 
there was when I got it.  I need to restore the free space that was on the 
eMMC originally.  I was able to install JRiver Media Center on Debian and 
Ubuntu without difficulty a few times before.  But this time, I get many 
"cannot write to file - no room on device" messages, and the install 
fails.  Using clean, remove and autoremove do not seem to help.

There seem to be many files in many folders in many directories that 
weren't there when it was brand new.  If flashing the eMMC is supposed to 
delete everything, it's not - so maybe my 'bone is broken.  I've properly 
reformatted each uSD card I use before burning , so there's never anything 
on the card except the image I want to use.  Is there any way to reformat 
the entire eMMC?  I hesitate to delete things when I don't know what they 
are - is there a list of the core files I need to preserve so it will still 
reflash from a card?

Best -

David

[beagleboard] How can I bring my 'bone completely back to as-delivered status?

[blues man]

My BBB's eMMC is apparently filled with useless junk after 2+ years of 
playing around with Ubuntu, Debian, Angstrom, Daphile, RuneAudio, JRiver 
etc etc etc. I tried to go back to the latest Debian image and reinstall 
JRiver Media Center but I'm getting multiple "no more room on device" error 
messages.  I know how to restore the defaults but I can't find any info on 
a complete reset that removes all files and data except the original 
content of the eMMC. I did have JRMC running fine last year, but like an 
idiot I decided to try Ubuntu and it's never been the same. I'm running MPD
