Please see adjacent post for that reply. Here's what happens when I try:
$ halrun
halcmd: loadrt hostmot2
halcmd: loadrt hm2_pci config="/lib/firmware/hm2/5i20/SVST8_4.BIT \
num_encoders=3 num_pwmgens=3 num_stepgens=0"
$ lsmod
Module Size Used by
hm2_pci 9116 0
hostmot2 56320 1 hm2_pci
hal_lib 36248 2 hm2_pci,hostmot2
...
And in /var/log/syslog, I find:
hm2_pci: discovered 5i20 at 0000:00:08.0
Though it didn't like the SVST8_4.BIT which I offered it:
hm2/hm2_5i20.0: invalid token in config string:
"/lib/firmware/hm2/5i20/SVST8_4.BIT"
hm2_5i20.0: board fails HM2 registration
hm2_pci: probe of 0000:00:08.0 failed with error -22
However, pasting the config pathname from /var/log/syslog to the
commandline, we have:
$ ls -l /lib/firmware/hm2/5i20/SVST8_4.BIT
-rw-r--r-- 1 root root 167061 2009-07-27 00:06
/lib/firmware/hm2/5i20/SVST8_4.BIT
So the "invalid token" is quite inscrutable at this stage.
Nevertheless, it is progress, I think. (And it's more accessible than
the GUI. They don't like me, and the feeling's mutual.) In fact, I'd
be delighted to give up entirely on the Applications->CNC->EMC2 thingo
if there's a list somewhere of what needs to be done for lift-off, so I
can bang it in a script.
Any advice on whether I've stumbled across one of the better ways to
diagnose a recalcitrant meeting of emc and hardware would be much
appreciated. Once I understand a bit more, I'd like to offer a few
relevant words for the "Integrator Manual", since it doesn't seem to
expound to the extent of prolixity in that area. (And we beginners need
all the hints there are.)
