One additional note: That git has the *bonegreen* dts file in it already. So git cloning that git, and running dtc in the src/arm/ directory for that file should just work. On Tue, Dec 15, 2015 at 3:58 AM, William Hermans wrote: > Your problem is very likely that you do not have the files > > #i

Doh, I just realized you're working with a 3.8.x kernel . . . These instructions above I believe will only work with 4.x, as that's what the sourced in this repo are meant for. However, I bet the device tree source files are exactly the same. But unsure if dt-bindings are different or not. On Tue,

Hi, I'm developing a system that uses PRU 1 to send a PWM to a switched mode power converter. When I first turn the system on, I want the PWM signal to be low. If the pin is high, I will pretty much surely blow my mosfets as current surges through my circuit. For some reason, when I first tu

The datasheet tells you the default for all the pins on power up. Some are high and some are low. Until the SW changes that, they stay and the preset levels. http://www.ti.com/product/am3358 Gerald On Tue, Dec 15, 2015 at 12:04 PM, Bill Gray wrote: > Hi, > > I'm developing a system that uses

Both will work, however you have to answer this question for yourself. Would you prefer to use systemd, or init as an init daemon ? Debian 8.x is Jessie, and will have newer packages. 7.x is Wheezy, and will have older packages, but also has been "proven". On Tue, Dec 15, 2015 at 1:45 PM, Bit Push

What I personally use, and this is not for a production system per se is Wheezy 7.8. Once that image is installed, I then upgrade to a newer 4.1.x kernel, and that's where I've been happy lately. I do a lot of personal testing of various hardware modules, etc, and have found this setup mostly solid

When measuring with an oscilloscope, keep the probe as short as possible. For example, short the ground to the probe tip and place the probe near the switcher. If you still see the switching spikes, then your probe ia too long. A ground wire of 3 or 4 inches is too long. As I said before, electr
