Hi there Simon...I realize it has been almost 3years since you posted this, but are you still using 3.8.13?
For Simon or anyone else comfortable with compiling machine kit on BBB from source...it would be very helpful to those new to machinekit if you could 1. Indicate the source of the starting image. 2. output a history of your work on the BBB from that image installation (for instance 'history -w history.txt') I see the instructions on the development portion of the website here, but it's the early steps that I'm struggling with. I'm hoping for a more 'dumbed down' set of instructions. Thanks so much, Alan On Sunday, August 11, 2019 at 7:42:29 AM UTC-4 [email protected] wrote: > I successfully compiled the 3.8.13 kernel with xenomai on debian stretch. > I am using the same xenomai userspace libs as on jessie (2.6.3) > and i compiled the latest machinekit from source directly on the BBB. > (Note: you will need a swap device during compilation, I used a swap file > on the SD) > > Interestingly I get the same speed and a really responsive GUI with this > kernel. > The same file that loads within 4 minutes on the exact same hardware and > the same SD card using the 4.19.37 kernel does load now within 20s! > The same performance as my old jessie box. > > So my recommendation is kernel 3.8.13 ;) > > I do not know why I see such a massive performance issue when using the > 4.19 kernel but for now I will stay with the 3.8.13 kernel. > If anyone has an idea what might cause the performance issue I would be > happy to learn about it :) > > Regards, > Simon > -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
