How do I install a single overlay? I'm writing and building a device tree overlay for a RTC chip (a DS1307) on a cape board that we designed. I want to communicate with the chip over the I2C bus no. 2 on a beaglebone black.
I know how to build the overlay using dtc, and I know I must copy the .dtbo file to /lib/firmware. My question is, do I have to run update-initramfs as well, or is it good enough to copy the .dtbo file to /lib/firmware? Anything else I need to do to install a single .dtbo? Another question: I see there is an overlay (BB-I2C2-RTC-DS1338.dts) available on https://github.com/RobertCNelson/bb.org-overlays. Maybe this will work for me with my DS1307 chip? Or I could install all the overlays with sudo apt update; sudo apt install bb-cape-overlays. Is it safe to install all the currently available overlays from Robert Nelson's site on my system? I have an older version of Ubuntu (16.04.3 LTS from Robert Nelson).
