It is probably an issue with the HAL pins iocontrol.0.emc-enable-in or
motion.enable. How are they connected in HAL (if at all)

Re: [Emc-users] 7i43 load error LinuxCNC 2.7.4

[Condit Alan via Emc-users]

Brain farts and other errors! I was trying to send the firmware via a parallel 
cable that wasn’t plugged into the cpu box. Fixed that! Then I realized that I 
originally bought 2 of the D525MW boards. I upgraded the bios on one of them, 
then my house was burglarized and guess which one got taken? So the second 
error was as Andy suspected related to an EPP problem. I got the bios upgraded 
and got the various loadf's and addf's sorted. So, now linuxcnc will fire up. 
However, I am getting occasional timeout errors. I seem to recall something 
about needing to pet the watchdog occasionally on the 7i43. Could this be 
biting me?
I don’t have the limit switches, spindle encoder or steppers plugged into the 
box yet and I am getting occasional joint errors (probably related to the limit 
switch inputs not being pulled up or down??). However, I can’t get the “Axis” 
power switch to go “on” when I click it and I haven’t figured out whether I 
have the estop switch wired correctly to the 7i43 board via the 7i42TA. I can’t 
really tell whether the “power switch” problem is related to estop or some 
other kerfuffle.

Thanks in advance,
Alan

The bitfile will be in /lib/firmware/hm2

But it sounds to me more like an EPP problem. I am confused by your
mention of a Mac.

Re: [Emc-users] 7i43 load error LinuxCNC 2.7.4

[Condit Alan via Emc-users]

Thanks Andy,

I found the error. The hal source on my Mac wasn’t the same as that on my 
linuxcnc box. I got the loadf’s and addf’s setup correctly now. However, now I 
am getting the error “Epp timeout while sending firmware". 

Would the error message for timeout be the same if it failed to find the file?

Where is the firmware (bit file) that is to be loaded found? I have a 7i43p 
200K board.

Thanks in advance,
Alan

Not really. Does the HAL parse the lines in the order here? or is there a
chance that it is attempting to set the gain before the component is
loaded.
http://linuxcnc.org/docs/2.7/html/man/man9/scale.9.html

Seems to indicate that the pin name is correct.

You could put "show pin scale*" in the HAL above the troublesome line then
start LinuxCNC from the command line. You should get a pin listing.
