Ahhhhhh sweet, thank you so much!!!! That'll make things so much easier. Geez I need to learn how those pinouts are done, haven't got to the rio-setup part much yet

Only LED atm is the FPGA "Done" pin. You told me to add one and I forgot. The art of doing stuff in a rush on display... my bad. Let's add one for Rev 1.1

Thanks, on a STEP pin, I assume it can it push enough mA to drive an opto-coupler inside the "generic" stepper driver that you get for say a NEMA34 size?

Yes of course. One pin of the 7760 can put up with up to 10mA.

My set-up, powered straight out of the board itself: 

4 relays = 120mA each
1 spindle rotary encoder = 90mA
1 MPG = 65mA
1 PROBE = 45mA
Total = 680mA

If other sensors are required (eg. several linear scales, anything power hungry) then I'd recommend them to be powered externally via 5V and common ground.

Great stuff, on the 5AX outputs, how many mA do you get at the outputs connector?

Not much I would guess, granted you only use the GND, Step and Dir pins (common drive set-up). Fwiw the 5V supply of the board is 2A. Using a MPS part (MP4560). Side note; strangely enough my datasheet rev claims MAX 60V where the MPS' revised/latest one claims 55V. Guess we can assume it's good enough up to 48Vdc psus. (Board's 5V switcher schematic attached).

Do the inputs 0,1,13 work correctly?
(as shown in halshow)

Does the encoder count in all modes?

have you set homing for any channel
(you are jogging joints which will only work until homed)

Hi,
i can not download the board-images (TOP-View), can you upload it directly in the forum ? i will start adding it to the rio-setup

EDIT: I managed to download the image

Gotta luv the folks at GOWIN SEMI, straight out of the manufacturer's jewelry box. Top silicon guys, highly recommend.
Official, we have our FPGAs secured, what will eventually power this LinuxCNC-RIO awesomeness!! We have 3 parts (for now). And I want one

Cool visuals ritual;

you may need stiffer pullup
resistors because the input sampling cause
higher leakage currents.

How to stiffer ?
I try pullup with resistor 4.7kOhm and 10kOhm not difference.

"An essential feature of DKMS is that it automatically recompiles all DKMS modules if a new kernel version is installed. This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade"

Yes, from what I have observed, the R8168-dkms driver is recompiled  as you describe. It requires the RT Linux-headers, It is quite time consuming to build. If it fails and it has a few times for me, you can end up with a system with no network. The solution is to sudo apt purge r8168-dkms. This is mentioned in the Debian package page for the driver, but its not intuitive. A couple of times, I had to boot into a different kernel (eg the non-rt one) to recover. Just in my experience it brings with it some issues so it may be better for the user to have control.

Can you post your hal and ini files?

Note that because inputs 0..3 are used for
analog inputs, you may need stiffer pullup
resistors because the input sampling cause
higher leakage currents.

Hi, PCW
Thank you for fast respond.

Before this problem I use 7i73  input for this
# The Axis select inputs
net axis-select-x <= hm2_7i96s.0.7i73.0.3.input-15-not  
net axis-select-y <= hm2_7i96s.0.7i73.0.3.input-14-not  
net axis-select-z <= hm2_7i96s.0.7i73.0.3.input-13-not  

all work correct



But now I want input 14 and input 15 for encoder 1more ,  then I try use any input .
I go to input-00 and input-01 for input select axis.
I'm use pull up on input-00  and input-01 (show picture in clip)  and try input signal for select X and Y axis

# The Axis select inputs
net axis-select-x <= hm2_7i96s.0.7i73.0.3.input-00-not  
net axis-select-y <= hm2_7i96s.0.7i73.0.3.input-01-not  
net axis-select-z <= hm2_7i96s.0.7i73.0.3.input-13-not  

I use hall show LED can change when select x-axis and y-axis (Z axis too) from my pendant but can't work for output on input-00 and input01  but input-13 work fine
have any idea ? I will try again .

It is stil Debian over the latest Pi kernel menu-config is still used as that how the image builder we forked works.
in short, we use Debian not Raspberian, but build  the official pi 6.6.4 kernel from source with the Official Linux Real Time (PREEMPT_RT) patch.

I got a black screen years ago and can't use my Pi4b at all because of it. I think it is to do with older versions, Upgrading the firmware worked for a while
