Hello dear members, I have built complete mainkernel on orange pi zero. I compiled u-boot, busybox, mainline kernel, and obtained dtb file. So, my pure system is running now. But, I do not how should I continue? For example, how can use wi-fi, how can use gpio drivers and how can import some libs like wiring pi to my pure system. What is next for development? Best Regards.
