If you have a couple of probes you can always flash one with the following firmware.

Hi Scott

I have two ST Link v2, flashed the CMSIS-DAP firmware to one of it.  When i plug this in either Windows or Linux PC i dont get a new drive for drag&drop operation of the Firmware ? It this working different then shown in your "Remora RT1052 DAPLink Programming" Youtube video ? Also i cannot find the firmware you have used in those video anymore, was this replaced with the FW linked above ?  I need to flash a NVem with rt1052 Chip

Log from the linux pc:

and a BIG thanks btw for your great work

edit: seems like i need to use the pyocd to flash tool

Is this what you are looking for?

There are precision levels, one brand is the Taylor Hobson Talyvel. It has a small sensor unit that is about 5" square, and can easily detect arc second changes. Slipping a human hair under one end drives it completely off scale.

I have one obtained surplus on eBay. it reads out to 0.1 arc second and after factory calibration is supposed to be accurate to 0.2 arc second. When I put it on the bed of my 3500 Lb. lathe it easily detects the change when I walk from one end of the lathe to the other. The advantage of this is it has magnetic damping so that if you pick up the sensor and place it on a surface, it settles within 2 seconds! A water level or oil bubble master precision level takes at least 30 seconds to settle.

This is doable, take a look at this thread:

forum.linuxcnc.org/38-general-linuxcnc-q...o-7i92-boards#311116

You can use mesaflash to change the EEPROM IP address
(probably to 10.10.10.11)

Hello Mates,

I can't access wiki for 15 days or so, is it out? Other than archive.org, is that another url?
 

SPAM removed.

I have translated mainly the MainWindow when I decided to test it, before putting more hours in it.
I have also tested to translate only one button "estop", the compiled .qm file had the translation inside.
 



I have also spotted difference between mine and @Franklin's .ts file. At the very beginning, the line="42" and line="43" is different. Does this means that these translations arent compatible between versions?

Hi.  Andre Fellow Norwegian here. Is it possible to talk to you on messenger or something?

When you activate too many overlays they can interfere with each other, because some pins have multiple functions. Some can also cause extra interrupts, so remove everything that you don't need and isolcpus should be placed after extraargs:​​​​​​​

That's nice, how is the latency? It might help to isolate the last 4 cores (isolcpus=2-5)if just isolating the last core is not good enough (isolcpus=5)

For spi, open /boot/armbianEnv.txt and edit the following:
overlay_prefix=rockchip-rk3399
overlays=spi-spidev
 

The latency not good actually, it's 75 us with 6*glxgears without SSH, however during this test, there was so many lags.
and with SSH it was 130 us.
and about:
overlay_prefix=rockchip-rk3399
overlays=spi-spidev
I have now this:

Do I need to change it? cause the spi is there already.

 

Thanks Peter and Tommy.
All the board jumpers are set to 5i24 settings.
There are no options in bios for pcie settings unfortunately.
They're is a 1x pcie slot on the mb but neither this, nor any other slots will allow the computer to boot with the 6i24 in situ.
As a trial, I have another (Windows) machine. That machine boots fine and the card is visible in device manager.
I think for now I'm putting it down to something to do with the computer, possibly mother board related.
One last question though, is there a minimum version of linuxcnc which needs to be used to allow the computer to recognise a 6i24?? Could it be something as simple as missing drivers?? IIRC the last time I updated was about 18 months ago.
Thanks!!

Hey Tommy,

Thanks. I actually just got a response from Peter.  He gave me the same link you gave me but told me there is a firmware that already has the modifications that I need.  It's called 7i96s_pmd.bin.  So it seems that as long as I can get this to flash I should be good to go as far as listening to the PWM from the Powercore from Rack Robo goes. 

Assss long as the Mesa board can pick up a 3.3v signal on that pin.  It seems that is what the Powercore is putting out as its PWM signal. I can also ask Peter about this and worst case I can run the input into a MOSFET or something similar to up the voltage into the Mesa...

Best,
-Dylan

Hello,
I'm getting more familiar with LinuxCNC and Mesa boards, converting a Biesse Rover 13s and have a 7I96s step and direction interface along with a 7I77 analog servo interface connected via the P1 expansion connector. I also have one 7I84 I/O board connected via the TB2 sserial and all is well, I can command the outputs etc. from halshow at all the boards but I need to connect two more 7I84s. I also have the 7I94T anything I/O Ethernet card but I'm using ethernet already on the 7I96S with 10.10.10.10. Should I reset the 7I94T IP to something other than .10 and use an ethernet switch or is there another way to use multiple sserial channels from the 7I96S?

By the way I really appreciate all the others that have gone before me and made this all possible! Thanks for the help!

I was typing up a post to ask for help getting LinuxCNC 2.9.2 running on a Raspberry Pi 4 B attached to a Raspberry Pi 7 inch Touch Display, when I finally figured out the solution. Thought I'd still make the post for helping others or possibly even future me if I have to rebuild this system one day.

The Pi Touch uses DSI for connecting to a Raspberry Pi and seems LinuxCNC doesn't have the required settings enabled in the config.txt by default. Not really a surprise as its probably an unusual pairing of hardware and OS.

The solution was adding the below text to config.txt
