How to use U-boot to Update the Flash Memory via usb?

Hi,

Now we can use U-boot to Update the Flash Memory though TFTP (MMC/SD boot mode can be used). http://processors.wiki.ti.com/index.php/GSG:_AM35x_EVM_Additional_Procedures#Using_U-boot_to_Update_the_Flash_Memory

Can we use U-boot to Update the Flash Memory via usb if customer board hasn't Ethernet?  Many AM35/37 customers will not use Ethernet. 

Thanks.

    Hi Jennifer,

       To update the flash from a USB device would also require that a host PC be attached because the AM35x ROM boot does not directly support USB.

       For more information about this please see this post:
