Looking at the /etc/rc0.d > directory might give you hints about the startup scripts to use. In fact, reboot was occured by the "lifeguard" protection. I use the flasher option "?-set-rd-flags=no-lifeguard-reset" to solve this. Now, I can boot without GUI and run my program. Nevertheless, when I run my frame buffer program, nothing is displayed. But, if I wait the screen shutdown and waik up the N770, the display is correct, but fix. Is there a solution to force the fb refresh ? I use to test this the "evas_fb_test" provide by the Enlightenment E17 library : it is ok on other devices or PC in FB or X11 mode (evas test on X11 in maemo is ok too).
