Subject: [PATCH 13/14] DockStar: Workaround to get the kernel loaded after a reboot.
|
|
|
|
Rebooting here always failed with:
|
|
|
|
scanning bus for devices... 3 USB Device(s) found
|
|
scanning bus for storage devices... Device NOT ready
|
|
Request Sense returned 02 04 02
|
|
|
|
But I've found a workaround using CONFIG_EHCI_HCD_INIT_AFTER_RESET
|
|
and a reset if scanning failed. After the reset scanning works.
|
|
|
|
Fixing the problem would be better, but therefor I would have to dig into
|
|
the USB-stack/USB-driver of U-Boot.
