Looking for a slim (console) debian, that works well with LEDscape

[Ryan Gosler]

Hi, I've been working with the official release for some time (3.8.13-bone50) and I've got LEDscape (https://github.com/Yona-Appletree/LEDscape) working well.  However I'm running out of space on the mmc, even after aggressive efforts to flense the OS of anything 'desktop' related.  I tried updating to the latest console debian in the wiki (3.8.13-bone69) and I love it, but I can't get LEDscape working.  Instructions for LEDscape are:

git clone git://github.com/Yona-Appletree/LEDscape
cd LEDscape
cp /boot/am335x-boneblack.dtb{,.preledscape_bk}
cp am335x-boneblack.dtb /boot/
modprobe uio_pruss
reboot

I noticed the dtbs have been moved to /boot/dtbs/3.8.13-bone69/

It seems that the am335x-boneblack.dtb there is identical to the one distributed with LEDscape.  I try LEDscape and I get the error:

pru_init:44: prussdrv_open open failed

So I try replacing the dtb and reboot and try again same result.  lsmod shows the uio_pruss module loaded.  At this point I'm thinking downgrade to bone50, but 'apt-get install-linux-image-3.8.13-bone50' has no candidate.  Any ideas?  Is there a slim debian with an older kernel I should try?  Or maybe a way to downgrade the kernel?  Or am I missing something I need to get LEDscape running?

Thanks for reading, greatly appreciate it!

Well... You can grab the deb for bone50 here:

http://rcn-ee.net/deb/wheezy-armhf/v3.8.13-bone50/

BUT..

you will have to manually extract/install

http://rcn-ee.net/deb/wheezy-armhf/v3.8.13-bone50/3.8.13-bone50-dtbs.tar.gz

to:

/boot/dtbs/3.8.13-bone50/

As that old deb doesn't install the *.dtb's...

Thank you.  What exactly is the 'firmware / linux firmware images' in that dir?  Does the Sitara have update-able firmware?

Best regards,

The firmware.tar.gz is just a relic before the *.dtbo's where built
into the kernel..

The firmware.deb, is just firmware from mainline.. Nothing useful for
this target.

Success!  Thank you sir.  Thank you very much.
