Hi.
I made a sd card for booting your reference site
https://forum.digikey.com/t/debian-getting-started-with-the-beaglebone-black/12967
When BBB is booted with a newly created sd card, mmcblk1 (emmc) is not recognized.
Of course, when I booted from the previously created sd card, BBB recognized mmcblk1 well.
What part do you think I made a mistake?
And how can I get it to recognize mmcblk1?
Please help me
Regards,
Share your full serial boot log, thru j1…

This is where you lost eMMC support…
Here’s what i would do…
First, open /boot/uEnv.txt and temporary disable:
debug: [enable_uboot_overlays=1] ...
debug: [enable_uboot_cape_universal=1] ...
Just stick a # in front of them, and reboot…
Next while booted in a default state, install:
sudo apt update
sudo apt install bb-u-boot-am335x-evm
Then install u-boot your microSD and eMMC via:
sudo /opt/u-boot/bb-u-boot-am335x-evm/install-mmcblk0.sh
sudo /opt/u-boot/bb-u-boot-am335x-evm/install-mmcblk1.sh
Now change, /boot/uEnv.txt back and reboot…

Hi Nelson
It works.
Thank you so much.
