Hallo,

I would like to use the sd card as extended harddrive to keep data on it. But, whenever I reboot the BBB (Debian 9) it will try to boot from sd card, even if this is not marked as bootable. How to solve the problem?

Kind regards
Markus

You can hack the u-boot source code, basically detect how many mmc interfaces you have found, and choose according to your needs.
