Re: [beagleboard] Re: Ubuntu snappy 15.04 image does not boot from SD card

Quite honestly, I have no interest in Ubuntu on this platform. For me, this is a true embedded platform, unlike many other boards out there. With that said, 99% of use cases that I can think of do not require a UI running on the board it's self, per se. Which is the only place I feel Ubuntu belongs

How those are triggered however, I had not figured out. I pretty much saw that kernel 3.19.x was used, and lost interest. On Fri, Jan 1, 2016 at 11:08 PM, William Hermans wrote: > >> >> *Second, the fact that booting the image flashed your eMMC is not cool. I >> was in fact wondering whether it

Thanks much for your efforts. For one, your results were the final nudge I needed to buy a USB to TTL serial debug cable. It’s possible that I didn’t have enough patience with LEDs all dark and not being able to see any indications of it actually booting. From booting the BeagleBoard Debian Whee

for whatever reason I could not get it to boot back into the uSD and it started to go back to flashing(cylon eyes). I looked at the partitions and there were only 2. After re-imaging the uSD card, I saw 4 partitions. And while I was re-imaging I tried to boot from eMMC and it would not, the fai

I have no idea *of* this image, ubuntu is not necessarily even a low priority for me. But I would imagine one could simply omit the block size parameter entirely. Regardless, I'm downloading the image now, and will mount it as a loopback, and see what I can poke around and find out. Maybe even tem

what I got so far looks like it's booting from mmcblk0( the uSD ) but then it goes into wanting to copy all 30GB from mmcblk0p1 to mmcblk1p1 and it fails for obvious reasons. I'm switching to a 8GB uSD card just to see what happens when it is able to complete. I don't know why it would want to

If you are in Australia, the January 2016 issue of Silicon Chip (a local electronics magazine) has an excellent full description of how to do this on a RaspberryPi. It should be exactly the same on a BB. Bill On Monday, December 7, 2015 at 12:29:06 PM UTC+11, Bill Dussault wrote: > > Greetings

ok, then maybe some of the things I used to do as a tech will help. I used to use the ole finger on critical parts in the area of question and see what/if something changes. This was easier to see on/with analog systems but digital streaming or debug looping could be used for digital circuits.

Re: [beagleboard] Re: Fickle HDMI issue with Beaglebone Black

I think the TV is recognizing the BBB has disconnected - it says searching for signals when the BBB is powered off or between boots, as it always says when there is no signal on the HDMI input. I wish moving the TV to another input would resolve this - it was among the first things I tried, but

[beagleboard] Re: Ubuntu snappy 15.04 image does not boot from SD card

That's why I said the card otherwise works fine. I've used it to burn to the card and boot from the card the BBB Debian Wheezy 7.8 (March 1) and 7.9 (Nov 12) images, with everything working fine. It's specifically when I turn to the Ubuntu image that things turn awry. But perhaps that's because

[beagleboard] Re: Fickle HDMI issue with Beaglebone Black

is there any chance the TV interface is not recognizing the BBB has disconnected and is not providing EDID information? Maybe just moving the TV to another input and then back again will reset the TV HDMI input? Shouldn't the EDID output be showing more than one supported mode? That's what's l

if this is the first time running from the uSD card then how about using a known good image just to verify you've got things booting correctly? Then you'll know it's your image and not something else. -- For more options, visit http://beagleboard.org/discuss --- You received this message becau
