Flash oops! bb green wireless

If you've written a NON-flasher image on the SD card, and it still
tries to run the flasher, you've got a strange eMMC configuration. Try
holding down the boot-select button to force the card to load u-Boot from
SD card (I believe for some years now u-Boot on eMMC is configured to
detect an SD card and then transfer to it to complete booting, but that
implies it is not using the SD card u-Boot)

If the boot-select with a non-flasher image works, you should be able
to mount the eMMC and explore it for incorrect configuration files. Or zero
it out so it can't boot from eMMC (and maybe eventually reflash it with a
known working image -- convert the working SD card to flasher).

Thanks Dennie.
I think that is getting me closer. I can now mount the SD on my Mac.
FYI to anyone reading this for similar help: If the Mac doesn’t see the ext4 partition a VirtualBox VM will not work as it doesn’t connect to the VM at all.

I can now see and edit the uEnv.txt file.
I’m not up and running yet but that gives me some more to play with.

You just need to assign the USB device to the Virtual Box VM; the native OS does not need to be able to read the filesystem. Also, you could use ext4fuse on you Mac to mount a ext filesystem. Or just Bootcamp your Mac with Linux. However, all of this is why I no longer use Mac systems.

Michael_B · October 31, 2019, 9:55pm

I know about that. It doesn’t work.
Not mine for sure at least with this version of OSX and the latest VirtualBox.

Thanks again all for help.

You could always get a Rasberry Pi to read the BB uSD.

Michael_B · October 31, 2019, 11:02pm

As it stands now I can read the SD and the env file etc.

The bbgw won’t boot so it does not show the board as a drive on a computer.

It just wants to keep flashing from the sd. Remove the sd and power up and it throws an error that the device to copy from doesn’t exist.

Using boot button does not seem to help.

I’m afraid I’m back to trying to get at the board drive in u-boot. I can’t find any examples of how to specify the interface and device.

jomoengineer · October 31, 2019, 11:53pm

Have you ensured the ‘cmdline=’ entry at the bottom of the uEnv.txt file is commented out? If not it will try to reflash the board.

Jon

Michael_B · November 1, 2019, 12:16am

It is rem’ed out on the SD card. I can’t get at any drive on the board itself since it won’t boot.
Using FTDI I can get to the board somewhat but don’t know how to LS into it when it says I am not specifying a proper interface.
All the googling about u-boot is either a generic Help dump that I can see in the terminal or talks about creating your own u-boot.

Thanks for the help.

Dennis_Bieber · November 1, 2019, 2:37am

Interesting... I don't have a Mac system, but do have Debian Buster
running in Oracle VirtualBox on a Win10 system.

Win10 will not see any Linux partitions when inserting the SD card
but... (and any attempt to access the card from Windows results in "do you
want to format?")

From VBox if I go to "Devices/USB" and select the "Generic Mass Storage
Device", I get icon(s) for the partition(s) [I'd gotten confused and
thought this was an R-Pi forum, so tried the R-Pi SD card first -- it pops
up 5 assorted partitions <G>; only one for BBB card]. The partition is not
initially mounted, I have to do that first by <right-click> the icon.

Dennis_Bieber · November 1, 2019, 2:39am

Would also need to buy a USB<>SD-card adapter, since R-Pi's don't have
an on-board (eMMC) so has to boot from its native SD card slot.

Dennis_Bieber · November 1, 2019, 2:47am

That implies a very corrupted eMMC to me -- since a normal SD card
flasher does not turn the eMMC into a "flash" mode.

We're out of my diagnostic experience -- I'd probably try using a
standard images from http://beagleboard.org/latest-images, editing the
u-Boot script to define it as a flasher (may not matter if your eMMC is
already trying to copy from the SD card), and flashing with that image.
Since normally the "flasher mode" text does not get copied to the eMMC (or
is post-flash modified).

If that didn't work -- I'd have see if JTAG is capable of erasing the
eMMC, and purchase a JTAG unit.

jomoengineer · November 1, 2019, 3:35am

Could you post the complete FTDI serial output of the board booting from the SD card and using the Boot button?

Jon

Michael_B · November 1, 2019, 1:17pm

As of now, it looks like when I power on with the Boot button pressed, literally nothing happens.
Here is what it looks like with no SD card and I boot the board.

no boot button pressed
no sd card inserted

For completeness, here is the boot hitting space to get into u-boot console.

It looks like with the uSD card installed and pressing the BOOT Button when powering on the board is forcing running the flasher from he SD card:

Begin: Running /scripts/local-bottom … done.

Begin: Running /scripts/init-bottom … done.

copying: [/dev/mmcblk1] → [/dev/mmcblk0]

When this is complete and the cylon LED pattern ends, the board should power down.

After this, it should be a matter of just powering off the board and booting it again.

If you are still seeing the panic while booting the board, I would redownload the image for the board and burn it to uSD card using something like Etcher and try again. If you can remove the “cmdline” comment at the bottom of the uEnv.txt file and then boot the board, it would be interesting to see if that makes a diff. You would have to comment it out again once the flash is complete though.

Uh... Power-off, remove [flasher mode] SD card, then boot.

jomoengineer · November 1, 2019, 5:10pm

Uh, in the second example, that is not needed since it is already commented out and the Boot Button is used:

##enable BBG: eMMC Flasher:
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3-bbgw.sh

If it were uncommented, then it would have to be commented out again before a boot. My end comment stated what was needed to use the flasher from the SD card instead of the Boot button.

RobertCNelson · November 1, 2019, 5:27pm

2016.03?

Just grab this image:

https://rcn-ee.net/rootfs/bb.org/testing/2019-10-28/stretch-iot/bone-eMMC-flasher-debian-9.11-iot-armhf-2019-10-28-4gb.img.xz

Use etcher to install it to a microSD:

https://www.balena.io/etcher/

Place the microSD card in the Beagle.

Take your finger nail and hold the "boot select" button..

Insert power..

Wait till all 4led's light up..

Remove finger..

Watch it flash the eMMC..

Run a difference utility on the two captures -- you'll see the
effect... (My comments will be within -=-=-=- markers)
