It is not me so clear.. Best regards, Stefano Babic

It is not me so clear.. The caller is in common code (see common/main.c line 76 -> 97). I think if I add CONFIG_MX25_CLK32 there whis will break a couple of boards which I don't want to. ;-) Also, we will have all this stuff cleaned up when the timer redesign comes in. Regards, Matthias
