got it - line 330 in arch/powerpc/cpu/mpc83xx/cpu_init.c does some EHCI configs masked by #ifndef CONFIG_MPC834x Removing this makes the board work again. It still hangs during "usb start" but this is most propably due to missing initialization. Will have a look and send a proper patch. After all I do like mondays ;-) Cheers, André MATRIX VISION GmbH, Talstrasse 16, DE-71570 Oppenweiler Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschaeftsfuehrer: Gerhard Thullner, Werner Armingeon, Uwe Furtner _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
