Hi there,
so far I have been booting my BBB from SD card.
Now I would like to copy the whole content of the SD card to eMMC, and let the board boot and run from there.
I don’t want to flash a new image, I just want to use the same data I used before from SD card, because I installed a lot of programs additionally to the clean image.
How can I achieve that?
Also, I have a Python app that starts automatically with boot and stores a log file.
How can achieve that the log file will be written onto SD card instead of eMMC?
Thanks in advance.
Hi @Steve12 it’s really the same flashing tool, which helps move between microSD and eMMC…
What image are you currently using?
Please report:
cat /etc/dogtag
Newer images have easier tools to do it…
For you python app, configure it use a directory mounted where the new microSD would be mounted…
Regards,
@RobertCNelson , thanky for the info.
Can you please elaborate what exactly should I do to flash the data to eMMC?
Dogtag returns:
BeagleBoard.org Debian Bullseye Minimal Image 2023-03-10
@Steve12 okay, that has all the new stuff…
First make sure bb-beagle-flasher is up to date…
sudo apt update
sudo apt install --only-upgrade bb-beagle-flasher
Next, configure it for microSD → eMMC via:
sudo cp -v /etc/beagle-flasher/beaglebone-black-microsd-to-emmc /etc/default/beagle-flasher
Now, run the ‘flasher’ copy script:
sudo beagle-flasher
it’ll format the eMMC and copy the microSD via rsync logging all data to the console.
Once it completes, just shutdown and verify by removing the microSD… On first-boot-up the ssh keys will be regenerated, so ssh will take a moment…
Regards,
Hi @RobertCNelson ,
I did everything you listed.
Then, after starting beagle-flasher, this is what I got:

I admit I have deleted first blocks from eMMC in order to run the system always from SD card, without the need to press boot button at each boot.
What should I do now?
So it’s only seeing one drive… Are you running from the eMMC right now with the microSD NOT plugged in?
Regards,
No, currently I’m running from SD card, at least I think so 
If I remove the SD card from slot, the LEDs do not light up at all.
What does the output of [sudo beagle-version] report? wondering if eMMC is disabled for some reason…
Regards,
This is beagle-version output:

well that explains where you eMMC went…
Regards,
Ah, your right, I disabled eMMC because I needed the GPIOs from P8_20 to 25 for my project.
So if I want to use eMMC, then I should comment out the line
disable_uboot_overlay_emmc = 1
in uEnv.txt and do not use pins P8_20 to 25, right?
Correct, so eMMC is out… I guess we are left with usb storage for secondary media.
