Hello everybody ,
I use the DM6467 and I want to install a webcam in my board, I use this link for help : http://wiki.davincidsp.com/index.php/USB_Webcam.
So when I plug the webcam to the board this message is displayed:
usb 1-1: new full speed USB device using musb_hdrc and address 4
When I execute this command:
root@10.1.1.104 lsusb | grep -i logitech
The kernel answer is:
Bus 001 Device 004: ID 046d:0870 Logitech, Inc. QuickCam Express
After that I wanted to verify if the webcam is register with any driver or not. And I use this command:
root@10.1.1.104:~# cat /proc/bus/usb/devices
The answer is:
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 1
B: Alloc= 0/800 us ( 0%), #Int= 0, #Iso= 0
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=04d6 ProdID=0000 Rev= 0.00
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=256ms
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 4 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=ff Prot=ff MxPS= 8 #Cfgs= 1

C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr= 90mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=01(Isoc) MxPS= 0 Ivl=1ms
E: Ad=82(I) Atr=03(Int.) MxPS= 1 Ivl=16ms
I: If#= 0 Alt= 1 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=01(Isoc) MxPS=1023 Ivl=1ms
E: Ad=82(I) Atr=03(Int.) MxPS= 1 Ivl=16ms
That’s why I download spca5xx driver to corss-compile it.
I modify the makefile :
KERNEL_VERSION = 2.6.10_mvl401-davinci_evm
KERNELDIR := /home/anis1/workdir/filesys/lib/modules/$(KERNEL_VERSION)/build
PWD := $(shell pwd)
MODULE_INSTALLDIR = /home/anis1/workdir/filesys/lib/modules/$(KERNEL_VERSION)/kernel/drivers/usb/media/
I execute this function:
CC=arm_v5t_le-gcc make
The answer is :
[root@localhost spca5xx-v4l1goodbye]# CC=arm_v5t_le-gcc make
Building SPCA5XX driver for 2.5/2.6 kernel.
Remember: you must have read/write access to your kernel source tree.
make -C /home/anis1/workdir/filesys/lib/modules/2.6.10_mvl401-davinci_evm/build SUBDIRS=/home/anis1/driver/spca5xx-v4l1goodbye CC=arm_v5t_le-gcc modules
make: *** /home/anis1/workdir/filesys/lib/modules/2.6.10_mvl401-davinci_evm/build: the file or directory is not found. Stop.
make: *** [default] Error 2
the build directory is not found and I have no idea how to change this line.
I need your help if you have any proposition or any comments please tell me as well.
Best regards
Anis Monser
