I agree, this happens. Which controller and driver do you use on the Sunxi hardware? btw you can check if this is a cache issue by disabling dcache (set CONFIG_CMD_CACHE in the config and use 'dcache off' before 'usb start'). You can also patch the arch/arm/lib/cache-cp15.c functions to do additional alignment checks (always a good idea) , just like I did that in arch/arm/cpu/arm926ejs/cache.c Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
