I used the command below for settting up the sd card as described on the wiki <http://elinux.org/BeagleBoardUbuntu#Method_1:_Download_a_Complete_Pre-Configured_Image> sudo ./setup_sdcard.sh --mmc /dev/sdb --dtb omap3-beagle-xm > cheers, > -roger > > > > On Wed, Oct 7, 2015 at 3:58 PM, Roger Quadros <[email protected] <mailto: > [email protected]>> wrote: > > > > On 07/10/15 16:54, Roger Quadros wrote: > > > Sven, > > > > > > On 07/10/15 16:13, Sven Bock wrote: > > >> Hello Roger, > > >> > > >> thanks for your reply. > > >> > > >> > > >> You don't need any uEnv.
