[beagleboard] Enhance U-boot to provide console over USB serial?

Is it possible to enhance U-boot such that (or does it already support) it presents as USB CDC class peripheral, so that standard OS drivers can connect, and get to the boot console that way? This has the disadvantage that you probably can't attach to the console until after boot is underway, s

Re: [beagleboard] SD card errors on hard reboot

As a matter of buffer hygiene, are you flushing the buffers to the sd card after every time you write to it? Something like the equivalent of the 'sync' command? If there is still unwritten info in the buffers when the power gets pulled, bye-bye data. In Linux, when the mounted drive is suddenly

Well we need to be able to pull the plug without damaging things. Is the best option then to have a battery system that allows BBB to listen for loss of power and gracefully shut down? Are there alternative methods? Troy Weber Mechatronics / Software Developer troywwe...@gmail.com 707-761-1644 sen

Re: [beagleboard] SD card errors on hard reboot

Well yes if you fail to unmount a file system you can have issues. On my systems i designed a battery backup system to prevent just the issues you are seeing now. It does not happen all the time but one time is unacceptable. Beaglebone is a live filesystem and you cant just pull the plug. -- For

I failed to attach it. It would not download the file (due to an io error). So the file I just attached is empty. When I cat the file on the linux system I get the following: # cat /media/sd/config/WaterfallDiceGame.json { "_id": 302, "name": "diceGamePrototype", "type": "system", "labe

Re: [beagleboard] SD card errors on hard reboot

Probably not. I should clarify that by a "hard reboot" I mean that essentially someone pulls the plug (or toggles a switch in the back). So no effort (to my knowledge) is made to unmount the micro SD card. On Monday, March 19, 2018 at 3:53:29 PM UTC-7, Wulf Man wrote: > > does it unmount properl

I will try that. I read up on *noatime*. *noatime* Do not update inode access times on this filesystem (e.g., for faster access on the news spool to speed up news servers). This works for all inode types (directories too), so implies
