Lcdproc with Sure Electronics LCD

stephenw10

Reading through the source code for the Sure Elec driver it expects to see a serial port not a usb device.

Surprising that the uslcom driver does not generate a new serial device. ???

You should ask in the lcdproc-dev package thread. The new maintainer, mdima, is using a SureElec LCD.

It looks like the device should appear as ucom0.
You need to have the ucom(4) driver loaded. Is it in the kernel?
The uslcom driver has been updated quite a bit since 8.1 was released, though it seems to recognise your device.

You could try adding the ucom driver from here:
http://files.pfsense.org/jimp/ko-8.1/i386/ucom.ko
Add it to /boot/modules.
Load it from the command line:

kld_load ucom.ko

Or add ucom_load="YES" to /boot/loader.conf.local and reboot.

How to upload ko file to my router? is it allowed?

stephenw10

Yes you can upload it. I usually use WinSCP uploading from windows.
Alternatively you can fetch it directly from the machine:


[2.0.1-RELEASE][root@pfsense.fire.box]/root(1): cd /boot/modules
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(2): /etc/rc.conf_mount_rw
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(3): fetch http://files.pfsense.org/jimp/ko-8.1/i386/ucom.ko
ucom.ko                                       100% of   20 kB  429 kBps
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(4): kldload ucom
kldload: can't load ucom: File exists
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(5): /etc/rc.conf_mount_ro

However as you can see on my machine ucom is already present in the kernel.

The only other thing is to check that the USB product and vendor IDs are in the source code correctly.
Enter: usbconfig dump_device_desc
Paste the output here.

This what i have now:

NOTE: This LCD works properly under FreeBSD 9-STABLE but not under pfSense 2.0.1-RELEASE (i386)

stephenw10

In that case it's almost certainly due to the usb ids not in the source.
Have you tried one of the pfSense 2.1 snapshots? Based on FreeBSD 8.3.

Under FreeBSD 9 does it generate a new serial port?

Looking at the 8.1 source it is in the usbdevs file.
The ucom functionality has been changed from 8.2 up so it's hard to see how to update.

Steve

ezyclie

It generates ugen1.2

I will try 2.1 tonight and will let you know asap.

ezyclie

It worse now, even my ntpd won't start with 2.1

stephenw10

Well 2.1 is a work in progress so some things may not work. I take it LCDd won't start then? The lcdproc-dev package won't work because it's compiled for 8.1 you have to use the FreeBSD pkg.

Steve

ezyclie

Yeap. i just re-installed 2.0.1 and finding new LCD that compatible with my Alix board and pfSense 2.0.1. Do you have any recommendation?

Thanks.

stephenw10

All my experience is with the Firebox LCD which is built into the appliance so not much use to you.
Probably best to ask in the lcdproc-dev thread. Although I note that the only reference to the LCD you have is in reply to a similar suggestion. ::)
