My BBB does not boot anymore.

Hi,

I have a big problem with my BB Black, it doesn’t boot anymore.

It boots, but the PC connection(SSH, storage mass, webserver …) doesn’t work(I do not even have the notification sound).
USR0 is bleaking(as usual).
USR2 is bleaking but very quickly.

My problem occured, when I tried to disable the HDMI Cape.
So I uncommented the line with the HDMI/eMMC cape in uEnv.txt.

And since it does not work.

I tried to flash my BB with the latest Debian Image, and it looks to have worked. But the result is the same.

Can you help me ? :frowning:

Thx (and sorry for my English)

Hi,

Hopefully I did understand you correctly (I am no native english
speaker...sorry...)

I think the problem is:
You have disabled the emmc, from which the beagle bone boots...

To get out of it:
Flash an image to a sdcard, insert the sdcard and boot it.

Best regards,
mcc

I already tried that, via USB and MicroSD, But it does not change anything :frowning:

I made a video to be more explicit https://www.youtube.com/watch?v=-bgwH99-PDI

Hi,

I saw that video...thanks for makeing it.

What did the debug console say, if you connect the serial output
header via an serial-to-usb adaptor (be careful with the voltage specs
of that adaptor!) to your pc?

May be your are able to intercept the boot process and setup up the
parameters - which normally are given via uEnv.txt - to correct values
and boot into sdcard.

How did you setup the sdcard?
Where did you diable emmc?

Best regards,
mcc

It looks like it is running, just the HDMI is turned off.
You should be able to ssh into it through the USB cable and modify the uEnv.txt to re-enable the HDMI.
Or, plug the SD card into a computer, modify the uEnv.txt on the computer.
It may be bypassing the SD card when it boots. Are you pressing the "boot to SD" button at power up?

I don’t have a serial adapter (I ordered this one http://www.ebay.com/itm/USB-To-RS232-TTL-UART-PL2303HX-Auto-Converter-USB-to-COM-Cable-Adapter-Module-/310676792112?pt=LH_DefaultDomain_0&hash=item4855c7a330)

I have setup the SDCard with Win32DiskImager.
I disabled the eMMC with uEnv.txt.

Good news, with a stand alone image it’s boot fine :slight_smile:

I am not able to ssh it, the partition is not mounted.

Apparently, I fix the problem !
I don’t know really why, because I just reflash it with a old debian image(like as did 10 times)

Apparently latest Debian Image (2014-10-08) are broken.

Really? Well i see no patch “fixing” it attached to this thread. Works for Me.

Regards,

Which board and debian version ?

"all"...

Regards,

I tried the lxde one, and it works great :slight_smile:
But I have a question, are they “full images” or just updates ? Because I started with 2014-05-14, then 2014-09-08 and then 2014-10-08 and now it works.
Another question, by “Console” it’s mean, cli only(SSH), or via Serial port ?

Thx

They are full updates, designed to flash any board with either blank
eeprom or an older image. The only issue the cropps up everyonce in
awhile, is just a really old bootloader or a bad power supply..

Another question, by "Console" it's mean, cli only(SSH), or via Serial port
?

Console just meas x11/lxde is not installed, otherwise it's exactly
the same underneath.
