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.

gmoccapy@machinekit:~/linuxcnc-org$ uname -a
Linux machinekit 4.1.0-0.bpo.1-rt-amd64 #1 SMP PREEMPT RT Debian 4.1.3-1~bpo8+1 (2015-08-12) x86_64 GNU/Linux

Who can help?

I should have included what I was running:

john@mint-shop ~ $ uname -a
Linux mint-shop 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 i686 i686 GNU/Linux
john@mint-shop ~ $ halrun
.
halcmd: loadrt lcd fmt_strings="LinuxCNC"
halcmd:

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.
