Hold the boot button, the button closest to the sd card, down while
applying power until all four USER leds are on. The button is small, so
be careful.
The uEnv.txt file should be on the sd card not your BBB. You can boot
your BBB without the sd card, inster the sd card, mount the sd card,
edit the /boot/uEnv.txt on the sd card. unmount the sd card. power down
the BBB. Insert power while holding the boot button down, wait until all
4 USER leds are on (only several seconds). If you have a debug cable,
see SRM section 5.12, you can see what is going on.

Sorry if this is answered somewhere, I looked around and couldn't find
anything on it in this forum.
Someone gave me a BBB to play with, it has Debian 7.x on it, I would
like to upgrade it to the latest OS image.
I went to this page (http://beagleboard.org/getting-started#step2) and
am following the instructions.
I downloaded an image onto my macbook from this page
- https://beagleboard.org/latest-images. I chose
Debian__9.2__2017-10-10__4GB SD__IoT
<https://debian.beagleboard.org/images/bone-debian-9.2-iot-armhf-2017-10-10-4gb.img.xz> .
I used Etcher to burn the image onto a microSD card.
I inserted the card into the slot on the BBB, held down the User Boot
button, inserted the power cord, waited until the four LEDs went off,
then let go of the button.
No joy. I was only booting from the microSD card, not flashing the
image into the eMMC.
I tried to follow the directions to convert the image to a "flasher".
The file that I am supposed to modify (/boot/uEnv.txt) was not in the
specified directory. However, I did find it in the /boot/uboot folder.
However when I edited it, the line that was I was supposed to
uncomment was not there. The script that the non-existent line was
supposed to run
(cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh) also is
nowhere to be found.
The system boots just fine from the microSD card, so i think the image
on there is ok.
So... what do I try next?
