Re: [beagleboard] USB performance vs governor

This was with the latest debian stretch image from beaglebone.org with an updated kernel. It seems to be using ondemand by default. I need wifi support as well. :( Dan On Monday, August 6, 2018 at 8:08:26 PM UTC-4, RobertCNelson wrote: > > On Mon, Aug 6, 2018 at 6:42 PM Daniel Kulp > > wr

[beagleboard] Custom board with AM335x PHY not found

Hi All, I have a custom board using AM3358, which is very similar to beaglebone. I am having trouble with bringing up ethernet. This is what I get when I execute *dmesg | grep mdio* *[4.412295] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6 * *[4.418430] davinci_mdi

[beagleboard] USB performance vs governor

I'm been trying to track down why the USB performance on my BBB's has been abysmal. I've discovered that the default on-demand governor is definitely a major contributor to the slowdown. Basically, with the ondemand governor, I'm seeing read performance off of a USB3 thumb drive of well un

[beagleboard] BeagleBoard-X15 Temperature range

Hello community, I did quite some research now, but unfortunatelly I am unable to find environmeltal specifications for the BeagleBoard-X15, especially on operating temperature. After several hours of googling and reading (un-)related I am still stuck with the only information being the minimu

[beagleboard] Re: BeagleBoneBlack GPIO folder randomly disappearing from sys/class/gpio

I finally figured this out. The service I had created was constantly calling the export on the pin, which I assume would cause the list to "refresh" or something like that. Stopping the service while the pin was "there" would cause the pin to stay. But if I stop the service when the pin is missi

[beagleboard] Re: BeagleBoneBlack GPIO folder randomly disappearing from sys/class/gpio

I have finally been able to get back to working on this again. I have now seen the problem on 2 different BBBs (but not a third one yet) so maybe this isn't a hardware problem? Here is an example of what I see. The GPIO will randomly appear and disappear on certain BBBs. You can use the watch -n
