您这个不带Kconfig和Makefile吗
可以修改 makefile
obj-$(CONFIG_XR17V35_PORT) += xr17v35x.o
KConfig
config XR17V35_PORT
tristate "XR17V35"
default m
我用dmesg看了一下， 有这个错误：
xr17v35x: no symbol version for module_layout
xr17v35x: no symbol version for module_layout
xr17v35x: no symbol version for module_layout
mxs_perfmon: no symbol version for module_layout
看来可能还是因为没有编译内核，直接make modules 导致的。这样出来的ko文件信息有问题
，看来要解决内核编译失败那个问题了

这个驱动模块只有一个makefile
Kconfig 不需要的
KERNEL_SRC = /lib/modules/`uname -r`/build
all: build
obj-m += xr17v35x.o
xrpci-objs := xr17v35x.o
EXTRA_CFLAGS +=-DDEBUG=1
build:
$(MAKE) -C $(KERNEL_SRC) SUBDIRS=$(PWD) modules
install:
cp xr17v35x.ko /lib/modules/$(shell uname -r)/kernel/drivers/char
clean:
rm -f *~ *.o
rm -f *~ *.ko
我配置内核，把网络模块去掉了，又报这个错。。。

这个驱动在内核编译成功之后，可以编译使用了，结贴，不过又出现了新的问题
