PfSense on a Celestix S-X MSA 4000
-
Thanks, I will follow your advice and try some USB LCD drivers.
Regarding Cavium encryption chips, I’ve found the drivers for Windows 2003 server and they match the ones installed on my device.
Check out the ftp site below and you see a Linux folder, I’ve extracted the contents and found some reference to BSD and FreeBSD but I don’t know what I’m looking at, it’s beyond my knowledge. :-[

I don't see any reference to FreeBSD drivers there. :(
It's possible though: https://plus.google.com/104092656004159577193/posts/f7y8btzZBbW

Sorry my bad.
Celestix S-X MSA 4000 Windows LCD driver info:
Celestix S-X MSA 4000 example LCD messages under Window OS:
Celestix S-X MSA 4000 display module:
Manufacturer: Varitronix
Model: MDLS-40263-LV-B-LED
Product: LCD Character Display Modules
Character Count x Line: 40 x 2 -
The LCD module looks pretty standard, the board it's mounted on looks more custom. It has the LEDs and the jog dial connected to it? The chip seems to be this:
http://www.simkits.com/downloads/documents/CY7C63743.pdf
If the USB to the LCD is just passed through then getting that going with lcdproc may not be too tricky.
The fact that the device is detected as a USB device with Vendor ID 0cb6 is not good as that's Celestix themselves.What is the state of support for the Varitronix display in lcdproc?

What is the state of support for the Varitronix display in lcdproc?
I think that’s part of the problem in that I don’t see any support for Varitronix display in lcdproc. :'(
In LCDproc file what would be the settings for:
ugen1.2: <vendor 0x0cb6="">at usbus1
ukbd0: <vendor 0="" 2="" 0x0cb6="" keyboard="" +="" lcd,="" class="" 0,="" rev="" 1.10="" 1.00,="" addr="">on usbus1Device=/dev/ugen1.2
I hope i've this correct?
Here is all the USB info i can find ;)

Hmm tricky. The datasheet for the Varitronix MDLS40263, PDF, appears to show that the onbaord controller chip requires some custom 8bit data protocol. May be less custom than I think, most LCDs seem to use something like this. I think it will all depend on how much custom code Celestix have put on the chip on their board. If it's all passed through and done in the driver then there is always a chance. If it's custom code in the chip then we have no idea how to talk to it.
Edit: The LCDproc HD44780 driver appears to support the NT3881D IC in that display:
@http://lcdproc.omnipotent.net/hardware.php3:hd44780 All displays using HD44780 and compatible controllers (like KS0066, KS0070, KS0076, LC7985, NT3881, SED1278, ST7066)
It's likely a matter of figuring how the chip on the Celestix board separates the various devices, control knob, LEDs, lcd data lines.
It seems other manufacturers have used that microcontroller for similar purposes. Google throws up some interesting results.
Steve
Edit: This looks promising:
http://www.freebsd.org/cgi/man.cgi?query=ucycom&apropos=0&sektion=4&manpath=FreeBSD+8.3-RELEASE&arch=default&format=html
It would require some mods to make it recognise the USB IDs. -
Hello, just bought a couple of celestix appliances on an auction. I just spend a few minutes to start one of them with a VGA monitor connected. I noticed That the system is booting up by first going into a GRUB bootloader. In this boot menu one can choose an recovery option. Choosing the recovery option the system boots into linux, with on the screen just a USB device driver. The lcd with jog dial shows a menu for the last good configuration or a restore of a Windows server 2003.
So to me it Seems there should be a linux driver for the LCD/jog module on the hard disk.
Good luck
Marc

Interesting. The Linux driver's probably not much good to us in freebsd but if they're using lcdproc it will give some good clues.
Steve

I think LCDProc i's not needed. it looks if they are only using shell scripts for the whole IO communication with the display.
These scripts in /etc/init.d are calling a function "lcd_functions" in /etc/hardware/current where current is a variable ScorpioII Scorpio X ( al versions of the celestix appliances. And as a big suprise the function itself is not a compiled programm but a sh script!!!
Ok this scripts calls a program in the Bin directory (Scorpio_readkey) that is communicating to a /dev/ttyX and has been compiled in GCC: (GNU) 3.2.2 20030109 (Debian prerelease)

Ah, nice investigative work. :)
Its a shame they're not using lcdproc. That way we would know exactly how the driver has to work.
Interesting that they have separated the lcd and led drivers.Interesting that the keydriver appears to be using a serial port. The chip they are using seems to be commonly used as a USB-serial converter so that could make sense. It is recognised as a keyboard by freebsd already though.
ukbd0: <vendor 0="" 2="" 0x0cb6="" keyboard="" +="" lcd,="" class="" 0,="" rev="" 1.10="" 1.00,="" addr=""> on usbus1</vendor>I guess a good test would be to just read ukbd0 while operating the knob and see what happens.

Excellent work guys,
I almost had given up on getting the LCD to work, but there could be light at the end of the tunnel. :)just read ukbd0 while operating the knob and see what happens.
Could you suggest how to go about that and I’ll give it ago?
Another good feature of these devices is the speed of the fans are controlled by the CPU temperature, unlike some WatchGuard Firebox boxes. ;)
On another note, does anybody know how to remap the network interface ports so they match the front panel?

You can just rename the interfaces in the webgui.
You can't use normal FreeBSD conf files in pfSense. All the configuration is stored in a single file, config.xml. At boot scripts use that information to write out the various config files, if you manually modify then they will be overwritten the next make you make a change. You can edit the config.xml file directly to make a series of changes but it's open to errors which could cause you all sorts of problems. ;)The keyboard is an interesting question, I've never tried. You appear to have three keyboards detected on that box. In /dev you have kbd0-2. My boxes here have no keyboards. Do you actually have a real keyboard attached? It appears you can get some info from each using the kbdcontrol command:
kbdcontrol -i < /dev/kbd1Some useful tests here: http://people.freebsd.org/~yokota/ukbd-howto.txt

Have just got my hands on a MSA3000 and I'm also interested in getting the LCD/jog wheel running with pfSense. Sadly my unit arrived without HDD so I don't have a working Windows system to drive the LCD otherwise I could have hooked up a logic analyser to see what messages the driver receives from the PC.
nanobot do you still have access to the executables and kernel modules? I wonder if we might be able to decompile the scorpioLCD and led kernel modules and get a bit of information as to how the PC talks to the LCD driver…?
-
It's very unlikely that the Celestix engineers designed a completely new custom protocol and display for their box. It's probably using common protocols and likely off the shelf components. It may have some custom firmware to drive the control wheel and leds.
At least some of the hardware appears to be using standard USB-serial converters so the first thing I would try would be to recompile the USB-Serial driver to recognise the USB IDs of the hardware in the box and see if you can talk to it from a terminal or read anything it's sending.Steve

I agree it's probably nothing too complicated or proprietary. It enumerates as a USB HID device, the jog wheel sends out key codes when it's rotated or clicked - that's the easy bit! This is what Ubuntu makes of the device:

I guess that would have been too easy!
So I'm at a little bit of a loss at the moment, I haven't done any USB driver development before. I can't imagine the driver is that complex, but at the same time I don't know how to send character / raw data to a USB HID device. I've started looking at pyusb but it's very low level stuff…

What I would do I were trying to design this…..
Use a standard keyboard controller IC for the jog wheel and LEDs (num,caps and scroll lock).
Use a standard USB-serial converter and connect that to a serial LCD.You have two USB devices there yes? One is detected as a keyboard already. There are programs in existence that use keyboard LEDs as indicators, it must be possible to try setting them manually. That should be an easy enough test.
The other USB device seen as ugen1.2 in the first posts here is probably the serial converter. I would try to recompile the cypress driver to recognise the USB vendor and product IDs used by it. If that works then try various LCDproc settings to talk to the LCD across it.Steve
Edit: I can't find a FreeBSD equivalent but in Ubuntu you can try using the setleds command.

Actually it's just a single USB device (combined keyboard and LCD). The problem is there doesn't seem to be any standard way to interface with displays over HID, so without a working system to sniff it is next to impossible to reverse engineer the protocol they have used on the cypress microprocessor.
Probably the easiest solution, certainly time wise, would be to replace the microprocessor with something LCDproc does support, such as an FTDI FT232 chip. This would probably mean losing the jog wheel, though there should be a pin spare for the activity LED at least…

On another subject I've been tinkering with different CPUs as the P4 3GHz mine came with by standard isn't the most energy efficient chip, and I know that some of the higher spec MSA boxes come with core 2 duo chips (E6420 I believe). I've tested the following:
Core2duo E6420 SLA4T (2.13GHz, 1066 FSB, 4M) - boots but unstable
Core2duo E6320 SLA4U (1.86MHz, 1066 FSB, 4M) - boots but unstable
Core2duo E4400 SLA98 (2.00GHz, 800 FSB, 2M) - boots, stable, BIOS reports incorrect speed?The E4400 gets reported at the BIOS as 50x10 = 500MHz! This is also reported in the OS I'm using to test (Ubuntu) but performance suggests it's actually running at the 2GHz. Doesn't look like it will be possible to run powerd in this sort of state however. You can set the FSB in the BIOS but this seems to get divided down by 4 for some reason with the E4400.
Not quite sure why the E6x20 1066 FSB chips aren't stable. It does take a lot to make them crash, I've been running memtest, mprime torture tests but the 'stress' command seems to reliably kill them given a few cycles. When they crash the system just halts, no input or output but the display remains frozen, very odd. The E4400 has been running with both mprime and the odd stress command for several hours now stable and has topped out at a core temp of 66c. All were tested with known good 2x 1Gb and 2x512Mb PC5300.
The stress command I have been using is
stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10sAll these oddities suggest to me a BIOS issue, though I cannot find an update for it (perhaps unsurprisingly, it being a custom motherboard). If time permits I may try to extract the existing BIOS and see if there is anything that can be unlocked settings wise.

I found the datasheets for the display they indicates that the module is using a "NT3881 or equivalent" display driver chip. on the LCDproc hardware page it indicates that that controller is compatible and supported under the hd44780.

Controlling the LCD itself is probably not a problem, there are drivers already in LCDproc for various hd44780 modes. The problem is controlling whatever it is connected to. It appears as a single USB device that does the leds and control wheel as well as the LCD.
