U-Boot-Console on BBlue

Hello,
which console is used by default when booting the Beaglebone-Blue?
Thanks a lot for your help,
have a nice day,
Bernd

uart0 on those jst connectors… Note, make sure you have power (or battery) applied on the Blue… Any random noise on uart0/jst, when no power is applied will destroy the board… (personal experience…)

Regards,
