Yes, it is possible. Exec Format Error: it seems that your module is not built using the headers of your goldfish kernel. Try this simple makefile when building your new driver (assuming hello.c as source):
obj-m := hello.o CROSS_COMPILE=arm-eabi- KERNEL_DIR ?= ~/goldfish/kernel/ all: $(MAKE) -C $(KERNEL_DIR) M=`pwd` ARCH=arm CROSS_COMPILE=$ (CROSS_COMPILE) modules clean: rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions modules.order Module.symvers Module.markers You need to take note that you need to export first CROSS_COMPILE variable to your current shell. (i.e. #export CROSS_COMPILE=~/<your- android-dir>/prebuilt/linux-x86/toolchain/arm-eabi-4.3.1/bin) Then you issue the command #make. I think this will resolve the Exec Format Error problem. As for the 'operation not permitted' problem in #insmod, it seems that the "Loadable Module Support" in your goldfish's kernel config is still not enabled. You can try this: <goldfish-kernel># ARCH=arm make goldfish_defconfig <goldfish-kernel># ARCH=arm make menuconfig [*] Enable loadable module support ---> (make sure to have this one) <goldfish-kernel># ARCH=arm ARCH=arm CROSS_COMPILE=arm-eabi- make Your final kernel will be arch/arm/boot/zImage. After booting emulator using that kernel, you can now do your #insmod in emulator shell. Hope that helps.
