OK.

I could do it with a do..while loop instead... this part was copied from the linux driver.
And there is a bug... instead of 'rtc->bcdsec' it should be 'sec'! Regards, José Gonçalves _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
