OK, I have made use of the MCP23008 and MCP23017, 8 bit and 16 bit GPIO expanders that are I2C connected on Raspberry Pis. The Raspberry Pi kernels include both an overlay (Device Tree Blob) and a driver module for the MCP23008 and MCP23017 chips. I would also like to make use of these chips on my beagle boards (a BeagleBoneBlack and a PocketBeagle).
I just did some poking around on my BBB, and there are neither Device Tree Blobs nor driver modules for the MCP23008 and MCP23017 chips. So, my question is: What is involved in building the missing driver modules and Device Tree Blobs -- I have built driver modules and even rebuilt whole kernels on x86 Linux boxen, so I have passing knowledge of how that goes, what I am really wondering: is there a repo with .deb files containing the "extra" ko files? Or tarballs containing the additional sources? I realize the BBB and PB are rather slow, so maybe I should cross build this on one of my Pis? Or is there an alternitive kernel I can upgrade to that includes these modules? Right now my two Beagles are running 4.14.71-ti-r80, Debian GNU/Linux 9, BeagleBoard.org Debian Image 2018-10-07. I did do a apt-get update/apt-get dist-upgrade about a month ago (May 14). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services [email protected] -- Webhosting Services -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
