armbian and orangepi zero plus ; I don't know programming, so I followed some tutorials on the Internet. MakeFile: ifneq ($(KERNELRELEASE),) obj-m += fb_ili9488.o else PWD=$(shell pwd) KDIR=/usr/src/linux-headers-$(shell uname -r) all: $(MAKE) -C $(KDIR) M=$(PWD) modules clean: $(MAKE) -C $(KDIR) M=$(PWD) clean endif
