What keeps you from using SPI?

But I think it would be a good joice for the buildbot.
The arduino part could be used as a watchdog and controlling unit for a ups.

Yes, my reaction was a little bit hasty.

Just like x86 boards.
But saying "Move along, there is nothing to see here" is not just opinion.
In this post you have explicitly advised against using linuxcnc, raspi3 and 
7i90.
It seems the business doing too well.

As Gene mentioned, there is a hal driver for the mesa 7i90.
http://www.linuxcnc.org/docs/devel/html/man/man9/hm2_rpspi.9.html


But unfortunately there is no golden future for arm based boards in linuxcnc, 
because the core developer does not support the arm platform any more.

As I can see, your linuxcnc version is 2.8.0-pre1-2771 and my version is 
2.8.0-pre1.2762 maybe your's broken.

Gene,

please reset only the 7i90 (disconnect and reconnect from power) and then retry
the linuxcnc command.

Maybe the board hangs in an undefined state.

Hmmm...

the message

 Unknown board: HOST

is from the probe_board funktion,
and the string "HOST" should be "MESA7I90".
Perhaps Peter knows when the board returns the

 "HOST"

string.

But why does it work with the plank

halcmd loadrt hm2_rpspi ?

Ok, disable the spi_bcm2835 driver with:

  dtparam=spi=off

in /boot/config.txt.

, copy the "kernel_rt-4.4.4-rt9-v7+.img" from the other/old sdcard to the /boot 
dir of the new/current sdcard
and put/change the following line in your /boot/config.txt:

  kernel=kernel_rt-4.4.4-rt9-v7+.img

Yes, this is no rt-kernel.

If this doesn't help, please send me your configs ( .ini, .hal, and the whole

Hi Gene,

'm back again from illness.

Hack in your remote console:

sudo apt-get install gksu
gksudo

enter in the "Run:" field

synaptic

click "OK".

:)

Have fun.

There is no need of reflashing with an external interface, the 7i90 has a 
fallback included.
See page 17 in the manual.
It's just jumper fiddling.

Re: [Emc-users] X on pi-3?

[W. Martinjak]

Gene,

the symptoms point to a power supply problem.
It's the "famous" brown out problem, due to bad designed power supplies.
Sometimes it's the cable of the supply with excessive voltage drop.
Yes this is unfortunatly the price of getting cheaper and cheaper
And I assume, that the hdmi connection pulls more amps then expected because 
the hdmi2dvi conversion.
I had similar effects with a bad hdmi cable.
One further negative impact of this brownouts is a degenerating filesystem.

A 1st discharge is a active usb hub for the keyboard,
and should this not be sufficient then use a better/stronger power supply.

Hi Gene,

ok, you were faster. :)

But for a better performance,

sudo apt-get install xcompmgr libgl1-mesa-dri

and with

sudo raspi-config

in "Advanced Options" activate the "GL Driver".

sudo reboot

Hey Gene,

there is not much room for interpretation:

https://forum.linuxcnc.org/27-driver-boards/31753-raspberry-pi-and-mesa-7i90-spi-works-well#82070

this "translation table" is rather clear.

Could you please slow down?
You are much to jittery.

Gene,

I believe for testing the SPI connection ssh will do it.

The hostmot2 part of the ini file should have:

[HOSTMOT2]
DRIVER=hm2_rpspi
BOARD=7i90
CONFIG=""


but I think you know that.

Testing with halcmd:

halcmd loadrt hostmot2
halcmd loadrt hm2_rpspi

expected output:

Base:hm2_7i90.0hm2/hm2_7i90.0: 72 I/O Pins used:

Hooking into this point.
Do you have a good instruction for flashing with rs422?
Is rs422 working at delivery state of the 7i90?

Re: [Emc-users] 7i90HD programming

[W. Martinjak]

As I have written:

   The bit files are in:

7i90/configs/hostmot2/

You need one of the 7i90_spi*.bit  files.
Then you have to flash the card on your printer port with

sudo ./mesaflash --verbose --epp --device 7i90 \
--addr 0xd010 --addr_hi 0xd000 \
--write configs/hostmot2/7i90_spi_svst4_8.bit

Change the addr and the filename!
grep the addr from  lspci -v.


The addr option depends on your system.
Maybe you can omit it and using the parport defaults.

No I would not.
I hope sometime linuxcnc can provide it.

But you can add:

deb http://buildbot.linuxcnc.org/ jessie master-sim
deb-src http://buildbot.linuxcnc.org/ jessie master-sim

and then executing

Yes therefore I wrote "change OR add". :)

Yes, something likethat. ;)

Back to the raspi install.

I will send you a link to an archive with files for installing the necessary 
packages per personal mail.

Its easier.

Archive content:

pkglistfile.txt
install-script.sh

and the linuxcnc arm packages.

Put all in a install directory of your preferred name.

cd to this dir.

Then type

sudo install-script.sh pkglistfile.txt >aptget.log 2>apterr.log

@ 1st ignore the errors and warnings.

Then 

dpkg -i linuxcnc-*

Now check the errors if there are fatals. :)

And then tell me please how did it go.

I wish you fun again,

Matsche

So, some suggestions about "Start With Raspi" :

download
https://downloads.raspberrypi.org/raspbian_lite_latest

It's minimal raspian image and a good point to start.


#from now i will comment all non commands

#Copy the image to one of your sd-card with
# sudo dd if= of= 
bs=4096
#ie: (please change the device!)
# get it with dmesg after plugging the cardreader with the sd

sudo dd if=2016-09-23-raspbian-jessie-lite.img of=/dev/sdg bs=4096
sudo sync (not really necessary)

#You do not need a hdmi for the first steps if you have a dhcp-server in your 
net.
#we are klingon tinkerer. ;)

#after the raspi has booted (blinking net leds) you can optain the ip with

#sudo nmap -sn (your subnet)
#ie:

sudo nmap -sn 192.168.1.0/24 

#then connect to the raspi:

ssh -Y pi@
(passwd: raspberry)


#now on the raspi:

# and resize the fs to the size of your sd-card.
# http://elinux.org/RPi_Resize_Flash_Partitions
sudo raspi-config

#comment off



if this works further instructions are following soon.

I think you need female to female jumpers.

Alternative suppliers and versions:

http://www.allelectronics.com/category/294/jumper-wire/1.html

btw: with this command you can list the configuration/pin-settings of the 
bit-file.

sudo ./mesaflash --verbose --epp --device 7i90 --addr 0xd010 --addr_hi 0xd000 \
--info configs/hostmot2/7i90_spi_svst4_8.bit

Yes, it drove me crazy... ;)

Direct link is here:

The bit files are in:
7i90/configs/hostmot2/

You need one of the 7i90_spi*.bit  files.
Then you have to flash the card on your printer port with

sudo ./mesaflash --verbose --epp --device 7i90 --addr 0xd010 --addr_hi 0xd000 \
--write configs/hostmot2/7i90_spi_svst4_8.bit

Change the addr and the filename!
grep the addr from  lspci -v.

Hi Gene,

it depends on which performance records you want break. ;)

I suggest going to the next mall, buy a raspberry pi 3, three fast micro-sd 
cards (1st for testing, 2nd for backup and the 3rd for the running end
version)
with 16GB (space for wear leveling) and a fast sd card reader.
As I've heard the 7i90 is on the way.
Equipped with these arms you can start cnc'ing with pi sized ordinateure. :)
Then I/we can assist you to setup the whole stuff.

Hehe..., its a eternal cycle.

Again,

there is already a driver for the Raspberry Pi and the Mesa 7i90 in LinuxCNC in 
the master branch.

Could you please describe how this 2 files can break the build system.

I think integrating is a little bit ambitiously formulated.
There are no high sophisticated dependencies.

And look at the buildbot output. There are many more breacking candidates.

The odd thing is that no one is curious or interested on the source (new 
driver) itself.
It's totaly irrelevant who checks in the code.

And my 1st problem with pull request was, I have on my github account a another 
linuxcnc fork with some changes but it's behind the upstream.
And syncing with upstream repos is in some cases cumbersome:

"https://help.github.com/articles/syncing-a-fork/
@ bottom is a tip: *Tip*: Syncing your fork only updates your local copy of the 
repository. To update your fork on GitHub, you must push your changes
.
"

And the 2nd Prob was, that git does not work properly in my qemu chroot 
environment where I compiled the source tree for the arm processor.
I had to copy the whole tree around.
Because of only 2 files.
etcetc...

And this whole theatre due to just 2 fucking files.

2 weeks development and then: sorry no stamp!

:P

Yes there is.

There are just few people who being versed with hostmot2 lowlevel programming.

It's right that the off-topic stuff quietens, but if you are the "wrong one" 
not just the off-topic stuff.

Again, what you are t... ;)

It's linuxcnc not machinekit.
Here is the log:

Hi Gene,

what are you talking about?
My setup uses a Raspberry Pi 3 plus a Mesa 7i90.
The raspi and the 7i90 ar connected with just a 6-pole ribbon cable.
It provides up to 8 channels steppers and servos etc.
And it needs a case with just 1 liter capacity. The whole setup.
 
Costs:
raspi3 = 35.00$
7i90 = 59.00$
case= I dont know... ;)

Yes it works.
I've made a sd-image for the raspi2 and it works without any changes on the
