Hi Glenson,

does it happen immediately at that line, or did you add any debug
output?

As soon as GD_FLG_DEVINIT is set, the output functions (puts, printf,
...) will search for the output device in a lookup table, which
unfortunately has not yet been initialized at that point (the lookup
table is initialized in console_init_r() which is called *after*
devices_init() has completed).

Perhaps the line "gd->flags |= GD_FLG_DEVINIT;" should better be
moved to console_init_r() ?

Cheers
