4.2 Downloading The Correct Version
At the time of this writing OPT3001 driver is still not merged in the Mainline
1
Linux Kernel tree. Because of that we have provided git branches for all Linux
Kernel versions starting with v3.14 all the way to v3.17.
On each of those branches, you will find the same OPT3001 driver together
with Beagle Bone Black devicetree changes for easy start.
Depending on which Linux Kernel version you’re using, download the correct
branch as per table below:
Linux Version GIT URL
v3.14 git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git opt3001-v3.14
v3.15 git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git opt3001-v3.15
v3.16 git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git opt3001-v3.16
v3.17 git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git opt3001-v3.17
To download any of those branches a certain level of knowledge about the git
version control system is required but the short version is below
