[beagleboard] Saving content from TI Wiki
Dear Beagleboard.org overseers, The TI Processors Wiki is being shutdown. I think valuable information would be lost that cannot be found in TRMs or Datasheets. For example, the following opcodes information was crucial while porting the GNU assembler for PRU: https://processors.wiki.ti.com/index.php/Programmable_Realtime_Unit Are you willing to transfer that and similar content to beagleboard.org ? Wikimedia page sources can be mostly automatically translated to MarkDown or HTML. So content could be served as a static page, with no need to host dynamic Wiki.

You need to build and install the userspace library to match that version of Xenomai.. The version should be reported by 'dmesg' so just get that matching version..

[beagleboard] Installing Xenomai on a BeagleBone Black with kernel 4.4.91-ti-r133
I am looking into installing Xenomai with a RT kenel based on 4.4.91-ti-r133, but the Xenomai install documentation I am finding talks about building/using a 3.8 vintage kernel. Is this documentation valid for the 4.4.91-ti-r133 kernel? -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

They look rather suspicious with the 50 second duration. Have a look at what their logs say, e.g.: $ journalctl -u dev-loop0 > 24.250s snapd.service > The snap package system is a bit of a resource hog and it primarily serves as a convenience for some minority use cases. Are you sure you need it on a BBB? Final thought - maybe your SD card simply has poor performance? I doubt it'll make a significant difference, but you can try flashing your image into eMMC or using a higher-end SD card. -- Kind regards, Tarmo -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
