Have you checked whether you have its dependencies enabled?
It seems like you have STAGING, I2C and GPIOLIB, but not ARCH_TEGRA.
Is your kernel configured for the right architecture? Are you using
ARCH=arm environment variable? You can do this by running the command:
$ ARCH=arm make menuconfig
In my .config file there is no string "NVEC" at all.
If it's generated by `make menuconfig` and you don't have the
dependencies, as far as I can recall it's not supposed to have this
string at all.
How to config this driver to be compiled?
I haven't worked much with kernel for ARM-based SoCs, but I think as
soon as you have your kernel properly configured for the correct
architecture and having all dependencies met you'll see it there. I
just tested and it shows up for me
Hi,
thanks for the hints. Here the steps I took on my x86_64:
saved my .config file.
sudo apt install gcc-aarch64-linux-gnu
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
make defconfig
make menuconfig
used / NVEC to find driver(s) and set them all to modules
make scripts prepare modules_prepare
make -j6
make -C . M=drivers/staging/nvec
Thanks for your support.
Bye Philipp
