OK, thank you very much !
It works !
sorry to bother you with my questions, now I want to set up my Asus u3100 dvb-t tuner
http://linuxtv.org/wiki/index.php/Asus_U3100_Mini_plus_DVB-T wich is supported in the kernel 3.7
there is also a git repository with a driver that works only with linux-3.2.1 and newer
what is the best way ? jump to 3.7 ? is it safe ?
or to 3.2.1 and patch it ?
is there an how-to for building and installing a kernel on nsa320 ?
do I need to upgrade uboot ?
