2009-10-14 01:38:20     Boot kernel from USB Flash Disk....

Hi,

      I came across the following problem, please give me some suggestion.

      The experiment platform is BF527. I plug an USB Flash disk to bf527's USB OTG port. When booting Linux uImage from the USB Flash disk, u-boot works fine, but when the kernel is booting up, it can not recognize the USB Flash disk. After that I press the reset button (only reset CPU, uImage is still in the SDRAM,), then enter command 'bootm', the kernel can boot and recognize the USB Flash disk successful.

      I think that after u-boot reads uImage from the USB Flash disk, u-boot should reset the USB host controller or some other things. Can you fix this problem? Thanks.
