Perhaps this can happen before the current patch 1? > diff --git a/board/nvidia/common/board.c b/board/nvidia/common/board.c > @@ -151,10 +152,6 @@ int board_init(void) > # endif /* CONFIG_TEGRA_PMU */ > #endif /* CONFIG_SYS_I2C_TEGRA */ > > -#ifdef CONFIG_USB_EHCI_TEGRA > - pin_mux_usb(); > - board_usb_init(gd->fdt_blob); > -#endif > +#ifdef CONFIG_USB_EHCI_TEGRA > +int board_usb_init(enum board_usb_init_type what_to_init) > +{ > + pin_mux_usb(); > + usb_process_devicetree(gd->fdt_blob); > + return 0; > +} > +#endif Moving the pinmux initialization might be dangerous; pin_mux_usb() might prevent the pins used for USB having a mux function selected that conflicts with some other pins selected mux function. We really do need to initialize all of the pinmux early, and not defer it. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
