Good day ,...
I'm sure im doing something wrong .
I have Acer 5102WLMI with m5602 integrated camera
Windows Driver:
ftp://ftp.work.acer-euro.com/notebook/aspire_5100/driver/Bison_CCD_5_0_0_10f.zip
lsusb output :
Bus 003 Device 002: ID 0402:5602 ALi Corp. Video Camera Controller
I've add the next line to the Makefile :
install:
mkdir -p $(DESTDIR)/lib/modules/$(shell uname
-r)/kernel/drivers/usb/media
install -m 644 -o 0 -g 0 m5602.ko $(DESTDIR)/lib/modules/$(shell uname
-r)/kernel/drivers/usb/media
depmod -a
so my make file looks like that :
obj-m := m5602.o
m5603c-objs :=
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
VERSION = 0.5
DISTFILES = m5602.c m5602_v4l2.c m5602_bayer.c m5602_sysfs.c m5602.h
Makefile README COPYING INSTALL
DISTNAME = m5602-$(VERSION)
all:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
clean:
@rm -f *.o *.ko .*.o.d *~ *.mod.c *.symvers .*.cmd
@rm -rf $(DISTNAME) .tmp_versions
@rm -f $(DISTNAME).tar.bz2
install:
# mkdir -p $(DESTDIR)/lib/modules/$(shell uname
-r)/kernel/drivers/usb/media
# install -m 644 -o 0 -g 0 slim321c.ko $(DESTDIR)/lib/modules/$(shell
uname -r)/kernel/drivers/usb/media
# depmod -a
install:
mkdir -p $(DESTDIR)/lib/modules/$(shell uname
-r)/kernel/drivers/usb/media
install -m 644 -o 0 -g 0 m5602.ko $(DESTDIR)/lib/modules/$(shell
uname -r)/kernel/drivers/usb/media
depmod -a
dist:
[ -d $(DISTNAME) ] && rm -rf $(DISTNAME) || true
mkdir $(DISTNAME)
cp -aR $(DISTFILES) $(DISTNAME)
tar cjvf $(DISTNAME).tar.bz2 $(DISTNAME)
rm -rf $(DISTNAME)
what I did was :
