I'm trying to boot from a USB flash drive. I essentially copy the u-boot commands for booting from the SD card. I'm running into a problem once the kernel has loaded:
Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. Begin: Waiting for root file system ... done. Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/sda1 does not exist. Dropping to a shell! modprobe: module i8042 not found in modules.dep modprobe: module ehci-hcd not found in modules.dep modprobe: module uhci-hcd not found in modules.dep modprobe: module ohci-hcd not found in modules.dep I plugged in /dev/sda1 as a place holder, but I can't find any indication that the initramfs was able to detect a USB flash drive. For some reason it complains about ehci-hcd and ohci-hcd modules not being found. The stock kernel is able to mount flash drives without any issues using the builtin usb-storage and musb-hdrc modules. [ 1.617727] Initializing USB Mass Storage driver... [ 1.625471] usbcore: registered new interface driver usb-storage [ 1.634288] USB Mass Storage support registered. [ 1.641729] musb-hdrc: version 6.0, ?dma?, otg (peripheral+host) I'd really appreciate any advice on how to detect and mount the flash drive. Do I need to make a modification to initrd? Or do I need to rebuild the kernel with the ehci-hcd / ohci-hcd modules? Why isn't it detecting the eMMC? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
