From your symptoms, it sounds like your eMMC may be confused or borked, probably with a bad sector or two somewhere. The on-chip controller is supposed to deal with this gracefully, but in my experience error cases are generally not well dealt with across the industry. Try wiping the entire eMMC, specifically by discarding all blocks (this tells the embedded eMMC controller it doesn't have to save the contents of any blocks. Use the blkdiscard command (from Jessie) or format the block device with ext4 (which performs a discard on all blocks) if you're using wheezy. Then try to dd to the entire device. If this fails, I suspect your eMMC is bad. Anyone else got a suggestion for testing/verifying the eMMC? -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Kernel Panic with eMMC flasher
On Mon, Nov 17, 2014 at 1:47 PM, Joe Spanier prcdsln...@gmail.com I am properly ejecting the card from my laptop after completing dd. Is that what you mean by sync? Here are the steps Im using: 1.

The sdcard shouldn't even be mounted on the desktop while you dd it. At least with unity it will still dd properly but the desktop is not aware and shows it mounted in it's previous state. A desktop unmount at this point is potentially harmful. I wish there was a simple way to verify the image after you've flashed it to the card -- does anyone know how to do this?

Re: [beagleboard] Kernel Panic with eMMC flasher
First of all, as far as the sdcard is concerned. sync has nothing to do with it, UNLESS, you are trying to remount the same exact sdcard. sync is not infallible, and as such will not always do what you think it may do. sync can take a considerable amount of time to achieve what you think it should achieve. What does a UI(Unity ) have to do with DD ? An application that has been around for YEARS longer than Unity ? All you can do is: write data remove media. sync. If the OS you're using screws this up, then it does not deserve to be used. Otherwise, it is user error.

Re: [beagleboard] Kernel Panic with eMMC flasher
I dont have a serial cable. Probably need to pick one up. I am properly ejecting the card from my laptop after completing dd. Is that what you mean by sync?

If you forgot to do this and yanked your card out after dd finished you cannot trust that you have an accurate and functional image. spread the word.

If you have the serial log from the flashing procedure this would confirm that.

How then do you know your getting a kernel panic? While flashing all debug info gets directed over the serial. I still haven't mirrored any of the progress back to hdmi output..

Re: [beagleboard] Kernel Panic with eMMC flasher
There is definitely a text output from the HDMI That is where Im seeing the kernel panic. I am trying to flash a new uSD now to try it. If it happens again Ill just take a picture of the screen.
