LinuxCNC + Orange Pi (allwincnc)

re video driivers and video acceleration:
:
i seem to have 'lima'
try sudo modinfo lima on your orange pi

from sunxi:
Lima is a project to develop a completely open source graphics driver which supports ARM's Mali-400 and Mali-450 GPUs.

somethng call Panfrost is similar for newer more powerful mali GPU's


also, if i view /boot/dtb5.10.34-sunxi/sunxi-h3-orangepi-pluse2e.dtb using mc
i can see any ascii text in the binary
and i see
sun8i-h3-mali.armmali400
and i see
gpu@1c40000

i am very sure i dont know what i am talking about
just seeing some related things on web

sources:
linux-sunxi.org/Mali#Lima_driver_.28Open_Source.29

tomp
I am _guessing_ that I have hardware video acceleration
note undersores

hahahah i just saw the lima driver webpage is on the wayback machine

(meaning it is so old it was put into archives for historians to look at )
its really not that old, its just so far behind whats new
( read the stepper stores by Stephen Baxter and Terry Prachett for a new take on time and a very new take on steppers)

Hi Tjtr33,

They already talk about the GPU hardware accel drivers issue in page 14.
Try to close the tool path drawing and swith to just show the DRO reading.
I can run that with the store 3A_CONFIG with no Follow issue.
But if I try to open a firefox. the Follow issue comes out.
I think is the cpu have the hard time for handle the feedback from "arisc.pwm.0.pos-fb" to "joint.0.motor-pos-fb" when it doing heavy duty work, Then it cause the Follow XX issue.

What does Archived mean?? no more development, unfinished?? I'm making a big pile of unusable LinuxCNC controllers. RPI4 with Remora got it up and running and found out it's limited to 25khz...#$%@^. ESP32.. Lossing hair over, Bought an H3 board and now the unfinished project is Archived and says don't load current as it will brick the board.. What version should I load? 

Hi Cncninja,

I was runing my pi with Armbian_21.02.3_Orangepipc_buster_current_5.10.21_xfce_desktop.img
You can find them below.

Hi forks,

Today, I do some search on net and find the method below to install OpenGL on Mali GPU to the system, and I get the better result with no error.
My speed setting is:
MAX_VELOCITY = 150.0
MAX_ACCELERATION = 200.0
SCALE = 1280.0
Even I can not get the glxgears in more then 150 FPS.

Please check the link below for reference :

SEE, as I mentioned earlier we just need some cleanups and a thorough going over of u-boot and the rt kernel. I am not impressed by the work done over at Armbian. Not sure if most of those devs have abandoned it or what the situation is over there.
