BBB Boot from uSD-Card

General Discussion
1

Hi all,

I have a BeagleBone Black from 2016 and recently decided to revisit the board to build some new projects.

My project requires both WiFi and a GUI, but the onboard 4 GB eMMC is too limited for what I need. Because of this, I would like to use a 16 GB microSD card as the main storage for the project.

Is there a reliable way to make the BeagleBone Black always boot from the microSD card without pressing the boot button and without flashing anything to the eMMC?

Any suggestions or recommended methods would be greatly appreciated.

Best regards,

Yes, remove MLO and u-boot.img from the MBR of the eMMC and remove any “uEnv.txt” file in the first eMMC partition…

Is there another method that doesn’t involve deleting files etc?
I prefer to keep the eMMC intact.

I’ve posted the least invasive method.

Good luck on your project!

Out of curiosity, I tried to flash to eMMC an older version of the OS and newer to the uSD. Now, I am booting from uSD-Card without holding the boot button. Now, I am happy camper.
