It may be caused by bad connections on the flying lead from the SD Card Board to the main Plug Board.
Take it apart and give them a 'wiggle', you have nothing to loose. :)

No, it is not.

It's an u-boot timing issue, just verified it with the manufacturer.

The resolution for it is to flash a fixed u-boot.

That may be your issue, but it certainly wasn't mine :)

You cannot accertain that it was not you issue, UNLESS it was happening repeatedly on EVERY reboot UNTIL you cleaned the leads (that, however was not mentioned in your previous post).

Please bear with me for a while:

- the log output you provided is EXACTLY the output of the timing issue the manufacturer confirmed,
- the issue occurs randomly (nondeterministically, if you will) every tens/hundreds of reboots, so your opening of the dreamplug and cleaning the leads was, IMO, the same workaround of the problem as I employed: disconnecting the mains and repowering the plug. Then you're good for another XX or XXX reboots.

I would simply prefer finding a piece of information about a faulty uboot before I had read your post. "You have nothing to loose" and "wiggle them a bit" did not provide useful for over a thousand of dreamplug units my organization purchased, that's all.

Cheers.

That's good to hear, I look forward to reading more of your posts sharing the wealth of experience that you have surely gained.

Listen, as far as I am concerned, it's perfectly fine if you find this particular u-boot error description boring and/or funny/generally uninteresting. Why the sarcasm though?

I did not find information about this particular uboot issue on the forum, the only mention that, in my opinion, was connected with it - was your post. I do think that, given how similar your log was compared to mine - it is highly unlikely that it was dirty leads or need of 'wiggling' them and not this particular uboot error.

Why would you try to discredit something that was admitted by the manufacturer? I am merely giving you and forum readers facts.

I do apologize if you felt somehow threatened by my posts, it was never my intention.
Cheers.

That's EOT from me, will provide further info when the patch from the manufacturer will prove itself.

Sarcasm ? I am serious (or I never would have bothered starting this thread), it is through 'sharing' that strong 'community's are built.

I take it apart to make a backup of the sd card. Same thing happened. Card was not found, controller was. I reopened it and replaced the card a few times and voila! It was working again.
Thanks Confusticated
