Re: [Emc-users] Rpi4B OS

[Sam Sokolik]

I have always used DD to create the images.  You just have to make sure you
are writing the IMG not the ZIP  Something like

sudo dd bs=4M if=~/Downloads/2020-05-01-linuxcnc-pi4.img of=/dev/mmcblk0

Re: [Emc-users] Rpi4B OS

[John Dammeyer]

Even for the initial upgrading of my STMBL AC Servo drive it wasn't possible to 
use Windows.  So I created a Raspberry Pi version that had all the tools 
including the source code for the two STM processors.  I used it to compile and 
load the firmware into the STMBL and do initial serial debugging.  That was 
several years ago now I think.   That SD card is in a little back with a few 
notes on how to do this.  So as long as I have a Pi3 around I can do things 
with the STMBL code. 

Even if you are  a Pure Linux Fan, it's handy to keep a dual boot PC around 
that has a version of Windows for those applications that aren't available for 
Linux.  This could be one of those if you are having trouble programming an 
micro SD card with the LinuxCNC image.

Re: [Emc-users] Rpi4B OS

[John Dammeyer]

Dave,
I only run Linux on Pi, Raspberry and the PC that is connected to the MESA 
7i92H.  To get LinuxCNC onto the Pi4 I have this file in the same desktop 
folder as the Balena Etcher on a WIN-10 Laptop.
 
2020-09-08-linuxcnc-2.8.0-pi4.img  came from the ZIP file I downloaded.   
 
Select the SD card location, click FLASH and when done insert into Pi4 which is 
connected to Screen, keyboard and mouse.  Boot and follow start up 
instructions.  Add or modify HAL and INI files and run LinuxCNC.  
 
This is really a brain dead installation.

So is the .img missing bits and pieces or are there steps beyond the

Confusion reigns!
The idea is to use the pi to drive a 7i90->7i33
I just tried the link John recommended .. 2.8.1 with the same result so 
it looks like I need to shift gears.
I'm lost;  I just need a version that will run linuxcnc with servos. 
Agnostic about which version.
If raspianos with uspace(?) will do that I'm happy. I just need 
something to WORK. ;-)
With some pain I can use my wife's  Mac and the rpi-tools to get an 
image on to the SD.

Re: [Emc-users] Rpi4B OS

[John Dammeyer]

Edited...
Hi Phil,
I only had issues with occasional loss of Ethernet messaging which required 
restarting LinuxCNC and homing again with the Pi4 and Mesa 7i92H.  Upgrading 
the power supply to at least 3A made a difference.   I used the same display, 
keyboard and mouse I used with the PC.  

Edit: Forgot to mention that I used the HAL and INI files from the PC version 
along with the Pi 2.8 version for LinuxCNC.  No building required.  Minor 
changes to the HAL and INI.

I'm back to the PC because so far I'm not changing away from my dual boot 
testing.  I have very randomly with no apparent reason also lost Ethernet with 
the Mesa on the PC.  But nothing that indicates why it might happen.  It's very 
rare and usually only when I've been mucking around with things.

Andy,

Have you experienced crashes in lcnc on a pi4b? I've had the software bomb
out on me a bunch of times, mainly when tapping the touchscreen too
quickly. Do you have any recommended settings for the best speed and
reliability?

Which Buster image, from where? The LinuxCNC one works for me, on a
variety of Pis.

I would suggest using the RPi imager app from Raspberry Pi, that seems
to be the most reliable way of writing the SD card.

[Emc-users] Rpi4B OS

[dave engvall]

Hi,
After much fuss due to a bad assumption I made I finally managed to 
flash the 7i90 for spi. Easy when you do it right.


However, loading an OS isn't going well:
Download a buster image as a .zip. Unpack to get an .img.
dd .img to 32G SD, stick in slot and power up.
I get 4 blinks ( no elf ) and messages on screen that complain about no 
bootxx.txt and elf and elf4 missing.
So I asking for help. I think I need a 7l kernel and uspace. 
Instructions styled for a dummy (I don't seem to be
getting any smarter with age) should move this along.  That is what to 
download and then move it to a 32G SD.

I've  spent way too much time spinning my wheels in the mud.
TIA.

Dave
