I changed the permissions of the modules directory. Now only a 'touch' error. Doesn't say me something...

corne@linuxcnc:~/CNC/Mesa/mod$ modcompile mb25ioc32.mod
/tmp/tmp40_g_2ol/mesa_modbus.c
touch: cannot touch 'mesa_modbus.c': Permission denied
Compiling realtime mesa_modbus.c
Linking mb25ioc32.so
cp mb25ioc32.so /usr/lib/linuxcnc/modules/

yeah so before I tried also to get CubeProgrammer to reinstall the bootloader but it failed, and now wonderfully it succeeded.
also:
firmware.bin => firmware.cur
my further drilling the setup led to understanding that the estop is tied to:

net user-enable-out <= iocontrol.0.user-enable-out => remora.SPI-enable
net user-request-enable <= iocontrol.0.user-request-enable => remora.SPI-reset
net remora-status <= remora.SPI-status => iocontrol.0.emc-enable-in

I do not fully understand, but remora.spi-enable is TRUE, status is FALSE and reset = FALSE, they are connected to a signal which is probably a physical signal on the octopus, but I dont know where. I accidentally made a short by connecting 3.3v to GND on DIAG0....

Anyway getting closer

p.s. I believe nothing was damaged!

With a fress install (from image) - without sudo i get this;

corne@linuxcnc:~/CNC/Mesa/mod$ modcompile mb25ioc32.mod
/tmp/tmpqf_2s56r/mesa_modbus.c
touch: cannot touch 'mesa_modbus.c': Permission denied
Compiling realtime mesa_modbus.c
Linking mb25ioc32.so
cp mb25ioc32.so /usr/lib/linuxcnc/modules/
cp: cannot create regular file '/usr/lib/linuxcnc/modules/mb25ioc32.so': Permission denied
make: *** [/usr/share/linuxcnc/Makefile.modinc:107: install] Error 1

I will try to do this: "Unless you have setup sshd to listen on port 5007 that is the the expected behavior."

it should be:

modcompile xxxx.mod

not

sudo modcompile xxxx.mod

at least that's what I have always done

 

sudo modcompile works, but again the same error.

Thanks you both. Yes I know that the security of the WAN is the most important security thing I must take care, but SSH, will at least secure part of the system. But anyway it is a very good advise. Thanks a lot.

I get an access denied error if I modcompile without sudo. Can that be the issue?

Sorry, apparently I didn't read your complete post. I'll try again

Gents,

mancave conditions: several cnc machines but will use one at the time. Plan to use lenovo T470 touch laptor with LinuxCNC on it. Each cnc machine will have Mesa on board (some ethernet model). One thing is bothering me: each machine Mesa card will have specific bit file. How about LinuxCNC on laptop? Is it possible to have several "profiles" so i can simply switch one machine off, disconnect ethernet cable, go to the next one with my laptop, plug eth in and just start machine specific profile and just use it? What if i want to use this nice black/yellow high contrast GUI 
on plasma, but then regular AXIC on the router then lathe specific one.

Can it be done?
 

Now it's obvious i'm a newby. I don't know where to find your example. It doesn't looks to be on my machine.

Strange that the example I mentioned above does not work. I just did a complete fresh install of 2.9.4 and it compiled ok, but same error at loadrt.

i found a bug in the avg call (wrong place)

if you use an avg filter and have problems with strange spikes, you should update


fixed in master and dev

That does not seem to compile

Can you try an example file from the modbus directory, say relayboard.mod

or alternatively here's a  simple .mod file I am running right now (linuxCNC 2.9.4)
that works with the common 32in 32 out modbus modules from Eletechsup:


 

Needs to be renamed to mb25ioc32.mod before compiling with

modcompile mb25ioc32.mod
