IRC log of #cubox of Sat 08 Apr 2017. All times are in CEST < Back to index

18:48 andrewalker Hey. Is it possible to break a Cubox by using too little power? I accidentally used a 5V, 2A power supply, instead of the 3A one.
18:48 andrewalker I can't make it boot anymore, and this is one of the possible reasons. I'm having a really tough time debugging it.
18:49 vpeter I think 2A is more than enough.
18:49 andrewalker I turned it on after a couple of months, and it was outdated. I flashed the SD card, and since then I can't turn it on anymore.
18:49 andrewalker not even with Ignition from solidrun
18:50 andrewalker vpeter: I even used most of your builds of libreelec :)
18:51 andrewalker all of them just show the solid run logo and some text, and then black screen. And the red led blinks twice and pauses, then blinks twice, and goes on.
18:52 andrewalker I already tried dd'ing from linux and mac, using different installers...
18:52 andrewalker any ideas?
19:09 andrewalker huh. It managed to boot with a different sd card. Weird.
19:22 vpeter sd cards can die :)
19:27 andrewalker sure! but two laptops were able to keep reading and writing from it, just cubox couldn't boot. I guess it corrupted something that mattered for boot...
19:30 vpeter Can you try to write image with dd and then read it back under different name. And then compare md5/sha256 checksum of both files.
19:32 andrewalker yes, doing that.
19:33 vpeter On broken sd card obviously :)
19:35 andrewalker haha, yes :)
19:38 andrewalker the one I wrote to the card (sha1sum): 45e9074fea71b52de12807ed94f432f885663377 LibreELEC-imx6.arm-8.0.1.img
19:39 andrewalker the one I read back: cf2897b40906c44b75cfdc42f4c750e9fb90e1ff LibreELEC-imx6.arm-8.0.1-rb.img
19:39 andrewalker and the weirdest thing, this is the output of dd when writing: 574619648 bytes transferred in 8.536046 secs (67316840 bytes/sec)
19:39 andrewalker and this when reading: 7892631552 bytes transferred in 136.942354 secs (57634700 bytes/sec)
19:39 andrewalker it read a lot more data than it wrote
19:40 andrewalker and took a lot longer too
19:40 andrewalker it read the entire card, actually
19:42 andrewalker oh well, never mind
19:42 andrewalker I'll use the other card, it's fine
19:42 andrewalker I'm glad it's fixed
19:43 vpeter Wondering why dd didn't fail.
19:44 vpeter Can you try to write again this time like dd if=.... of=.... && echo OK || echo ERROR
19:45 vpeter Maybe I should add 'Verify' option in my USB&SD Creator app.
19:46 andrewalker it echo'ed OK :(
19:46 vpeter can you add option conv=fsync to dd ?
19:47 andrewalker yes
19:47 andrewalker dd: unknown conversion fsync
19:47 andrewalker I'm on Mac now
19:47 vpeter Unknown option there :)
19:48 andrewalker yeah, apparently :)
