Error loading lcd was created by newbynobi
Hallo,
I am trying to get my display working.
It is connected to a 7i76e and a 7i74 to a 7i73.
But that is irrelevant at this state,
I added in my hal file only one line
loadrt lcd fmt_string="LinuxCNC"
nothing else and I got:
usr/bin/rtapi_app exited without becoming ready
insmod for display failed, returned -1
This error does not help much.
I tested with 2.7.5 and master with kernel 4.1.0-0.bpo.1-rt-amd64
(Jessie with machinekit kernel)
dmesg, linuxcnc.debug and text do not contain any helpful information.
is lcd depending on aspecial kernel?

Norbert,
It's loadrt lcd fmt_strings="test"
You are missing the "s".

Same here,
lcd does not become ready, so it is a kernel question and may even be related to 64 bit.Who can help?

I should have included what I was running:
I don't run 64-bit anything so I can't test that.

Looks an issue with the Preempt RT kernel, I get the same "waiting on....." with my Preempt RT 32-bit on LinuxMint.
