Subject: Booting PhyTec PCM043/IMX35 from USB/SD-Card
Date: Wed, 23 May 2012 17:43:52 +0200 [thread overview]
Message-ID: <4FBD05B8.40001@crane-soft.de> (raw)
Hi all.
I am trying to setup my PCM043/IMX35 board to boot from the
USB MMC card but til now I do have have any clue how to manage.
Searching the net, did not provide any hints regard that board.
I'ld like to have barebox to allow me to use the USB/MMC card
as boot device. Is there a chance to boot from SD-Card at all?
-- barebox configuration data --
I have enabled USB support (USB_EHCI/OHCI and USB_STORAGE ) as well as
CONFIG_UBI=y
CONFIG_DISK=y
CONFIG_DISK_WRITE=y
...
CONFIG_USB=y
CONFIG_USB_EHCI=y
CONFIG_USB_OHCI=y
# CONFIG_USB_ULPI is not set
# CONFIG_USB_TWL4030 is not set
CONFIG_USB_STORAGE=y
# CONFIG_USB_GADGET is not set
# CONFIG_VIDEO is not set
CONFIG_MCI=y
...
CONFIG_MCI_STARTUP=y
CONFIG_MCI_INFO=y
CONFIG_MCI_WRITE=y
CONFIG_MCI_IMX_ESDHC=y
CONFIG_MCI_IMX_ESDHC_PIO=y
