[beagleboard] Meassuring CPU load on BeagleBone Black
Hey there, Using the BeagleBone Black running 3.8.13-bone47, and I'm searching for a method for measuring the CPU load. This may be a standart Linux command, but i havn't been albe to find any. Somebody know of a effective method for this?

Hi! I use libpruio http://beagleboard.org/project/libpruio/ for PWM output (available on 14 header pins). It supports full control over the PWMSS registers: - Up to 8 PWM signals (6 x ePWM, 2 x eCAP). - Up to 6 of them can get synchonized (3 x 2 x ePWM) or - up to 5 of them can be independant signals (3 x ePWM, 2 x eCAP).

Re: [beagleboard] Wl12xx
Hi, As a follow up I agree with the previous statement that wl127x drivers have no device tree support. So you'll need to merge device tree support from wl18xx drivers. As far as I can remember there are no major changes to parameters passed by device tree to WiFi driver from wl127x to wl18xx. As long as you successfully pass the wl12xx probe function without an error you should be ok. Caveat is that I've not done this exercise. Iain On 19 Aug 2015 15:56, drhunte...@gmail.com wrote: Hi, Which wilink device are you building for? The wl18xx family is now fully supported in 4.1 kernel. There is a device tree file for the wl1835 cape in the kernel that is best place to look. If you are looking at wl127x or wl128x then device tree will be similar but you'll need to build the Wi-Fi drivers out of tree. For the wl1835 cape look at the ti processor wiki for a page to describe full build and configuration on 4.1 kernel.

Re: [beagleboard] RAM 1GB option
From a schematic and PCB standpoint we can go up to 128GB, after the first of the year. Assuming we have enough powernobody gripes about ti not working on USB...and people are willing to pay.and the SW can support it, it should be doable.

How much eMMC storage do you need? I have yet to select the DAC/CODEC. Some TI part, most likely. I need to drive small speakers, so it'll probably be one without an integrated amp. I also only need mono, but to make the cape a little more capable (lulz), I'm going to try to make it stereo with an amp bridging option. As to how much, it's an open-ended question that would depend on cost. 16 GB? 32 GB? 64 GB? More is always better, but cost is a limiting factor. I do know the current 4GB isn't enough, but 8GB would be enough to store the library of content that inspired my project. -- Rick Mann rm...@latencyzero.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] autonomous boat project
We are hoping to use the beaglebone black on a project with 10 small autonomous boats with about 1 Watt-hour lot of onboard battery power (mostly used for propulsion). We need to stream audio data up to 30 kHz from each boat via local wifi and also send instructions to the propulsion units on the boat. If anyone has ideas, experience, or references on how to get started or the suitability of the beaglebone black for this project, we would be most grateful. We have funding and would love to collaborate with anyone on this project.

[beagleboard] Re: BeagleBoard.org Approved accessories
Only other feedback I got from this on IRC was to not approve any hardware that required closed source to function properly. Sounds like a pretty reasonable request. Seems like this is a go.

[beagleboard] Re: Where are the PWM Overlays stored?
Thanks for the offer. Since I wrote, In addition to Robert's response, I also found a good article at https://briancode.wordpress.com/2015/01/06/working-with-pwm-on-a-beaglebone-black/ and, after disabling the HDMI cape in uEnv.txt, was able to get P8.36 working as PWM. My ultimate goal is to be able to write stuff in C to run under the auspices of the OS and use it's utilities for various things while still trying to write as close to the hardware as the OS will let me (since I have a lot more experience writing bare metal). Thanks again! On Tuesday, August 18, 2015 at 3:15:11 PM UTC-4, tobst...@gmail.com wrote: No idea where they have gone. That is the only location I know about.

[beagleboard] Re: BeagleBoard.org Approved accessories
Approving accessories is a little tricky. No revision control and no source control. We see this all the time on Wifi modules. Different revision silicon and different silicon all together. You would need this to be a direct relationship with the supplier of the accessories. And we woudl need to find a away to test hem and stay in step with the suppliers on any changes. We also have the case where the Linux kerenl gets updated every now and then which can lead in some cases to an accessory no longer working. This will take some hard resources to do this correctly.

Re: [beagleboard] RAM 1GB option

I need to drive small speakers, so it'll probably be one without an integrated amp. I also only need mono, but to make the cape a little more capable (lulz), I'm going to try to make it stereo with an amp bridging option. As to how much, it's an open-ended question that would depend on cost. 16 GB? 32 GB? 64 GB? More is always better, but cost is a limiting factor. I do know the current 4GB isn't enough, but 8GB would be enough to store the library of content that inspired my project. -- Rick Mann rm...@latencyzero.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
