Re: [Ltib] how to build a kernel module using ltib? (docu)

[Arun Kumar]

Hi ,
I am configuring TouchScreen(egalax touchscreen) drivers using USB Support for MPC5200B processor.

Configured the kernel using ./ltib --configure for USB support as shown below.
Omitting the options which are not set.
#
#USB Support
#
CONFIG_USB=y

#
#Miscellaneous USB options
#
CONFIG_USB_DEVICEFS=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y

#
# USB Host Controller Drivers
#
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_OHCI_HCD=y
CONFIG_USB_OHCI_HCD_OCP=y
CONFIG_USB_OHCI_HCD_PCI=y
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_UHCI_HCD=y

#
#USB Input Devices
#
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_EGALAX=m

My Problem here is the touchscreen drivers are working, but on touching the screen
the XY Coordinates are pointing exactly opposite to the touched point.

Can you please help me out in correcting XY Coordinates for the driver,
so that it exactly points to the position where i touched.

Thanks & Regards,
Arun.

Note: When you are in the kernel configuration menus, you can type /USB to search for USB related config options and how to find them in the menu tree.

For the USB config:

USB_FILE_STORAGE [=n]
Prompt: File-backed Storage Gadget

Here is a complete list of USB setting that I have used successfully to do the gadget file operation on the MPC8349E-mITX platform (I have omitted many options that are not set).
