Hello,
I am trying to add some module code in a driver, but it seems a build image did not include my change. Therefore, I tried to add a debug message to see if my change applied.
I tried to add a debug message in selinux_init in vendor/nxp-opensource/kernel_imx/security/selinux/hooks.c as following.
static __init int selinux_init(void)
{
pr_info("SELinux: test Initializing.\n");
However, every time flashed boot image showed SELinux: Initializing.
On the other hand, I have checked out/target/product/evk_8mq/obj/KERNEL_OBJ/arch/arm64/boot/Image. It included my test code. I also tried to decompress out/target/product/evk_8mq/obj/KERNEL_OBJ/arch/arm64/boot/Image.lz4 and it also included my test code.
I don't know how to check boot.img, thus I'm not sure whether boot.img included my test code or not.
My build environment is ubuntu 22.04
nxp source is imx-android-13.0.0_1.0.0.tar.gz
evb is imx8m evk8mq.
Could anyone help me how to make a correct boot image?
