I have based this on the 5120 sample config files found on EMC2 CD.
Kirk Wallace sent me some directions, and:
1) i have no "man hm2_7i43" on my linux (no manual found answers my
console), and i have downloaded it as an Ubuntu complete CD image from
LinuxCNC website.
You have m7i43_hm2 but not hm2_7i43; that probably means you're running
EMC2 2.2.5. Support for the 7i43 is still evolving rapidly, I'd suggest
at the very least running the most recent version, 2.2.6, which is also
available from linuxcnc.org.
There are several known bugs in the 7i43 driver in 2.2.6, you'd be much
better off checking out and compiling the CVS TRUNK version.
Instructions for doing that are here:
<http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2>, if you
installed EMC2 from one of the live CDs on linuxcnc.org, you can
probably skip to step 2.2.
There are two drivers that talk to the 7i43: m7i43_hm2 and hm2_7i43.
m7i43_hm2 was introduced in 2.2.5, it is sort of an early prototype of
the hm2_7i43 driver. m7i43_hm2 is deprecated and should not be used.
hm2_7i43 (and its companion driver, hostmot2) were introduced in 2.2.6.
This is where all current development and bugfixing is happening. All
new configs should use hm2_7i43 and hostmot2.
*Test 1*
# Install driver.
loadrt hostmot2
loadrt m7i43_hm2 config="firmware=SV8B.BIT num_encoders=1 num_pwmgens=1
num_stepgens=0"
*Error 1*
Debug file information:
7i43_motion.hal:3: Can't find module 'hostmot2' in
/usr/realtime-2.6.24-16-rtai/modules/emc2
4913
The error message is saying that the 'hostmot2' driver module cannot be
found, presumably because you're running emc2 2.2.5 which does not
include it.
This Test1 configuration is what you should be trying to get working,
preferably by installing EMC2 from CVS.
*Test 2*
# Install driver.
#loadrt hostmot2
loadrt m7i43_hm2 config="firmware=SV8B.BIT num_encoders=1 num_pwmgens=1
num_stepgens=0"
*Error 2*
Debug file information:
insmod: error inserting
'/usr/realtime-2.6.24-16-rtai/modules/emc2/m7i43_hm2.ko': -1 Unknown
symbol in module

7i43_motion.hal:4: insmod failed, returned -1

This error message is a bit more cryptic. First of all, as i said
above, m7i43_hm2 is deprecated and should not be used. The error is
because that old driver took in its configuration in a different way
than the new one. You're using the command-line syntax for the hm2_7i43
driver, but passing it to the m7i43_hm2 driver, and it's saying that it
doesnt expect the "config" argument.

This is the only one that makes lights on the card to flash
--------------------------------------------------------------------
*Test 3
*# Install driver.
loadrt m7i43_hm2
loadrt m7i43_hm2 config="firmware=SV8B.BIT num_encoders=1 num_pwmgens=1
num_stepgens=0"
*Error 3*
Debug file information:
insmod: error inserting

Here you're loading the m7i43_hm2 driver twice, which is twice as wrong
as loading it once ;-)
It works the first time and flashes the LEDs on the board because you
didnt give it any incorrect load-time arguments. Then it fails the
second time and emits that error message because the first instance is
already loaded and it prevents the second one from loading.
Compile emc2 from CVS, use hostmot2 and hm2_7i43 with the config=...
argument from Test 1, and let's see how it goes.
