I have only one monitor, it is difficult to switch every time.

With knowing the IP address and any ssh client (windows: PuTTY) you can log in as root (press enter on password request). ;-)<br /><br />Back to the problem:<br /><br />cat /proc/cmdline<br />console=ttyO0,115200n8 video=HDMI-A-1:640x480@60 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait<br /><br />looks like this - no screen on HDMI.<br /><br />Anyway, these were my first 20 minutes touching the beaglebone, I'll keep on going.<br /><br />best & thx for postingChrishttps://www.blogger.com/profile/14410769055036624421noreply@blogger.comtag:blogger.com,1999:blog-721739666225174355.post-47740868263717021572013-06-23T21:17:26.896-05:002013-06-23T21:17:26.896-05:00You read my mind, neglected to order the serial ca...You read my mind, neglected to order the serial cable, and can't see anything on my hdmi display out.
