I think we are getting closer, I am still seeing the same thing. HDMI monitor shows a blinking Mouse Pointer and a blinking courser in the upper right corner, Browser reports " The FabScanPi server is currently not running". I configured the PI BIOS for desktop mode and no SSH.
Any thoughts on where to go from here? Do I have bad hardware?
Thanks again and looking forward to hearing from you.

The HDMI monitor will not show more than a blinking curser :) The whole software is browser based. But you are right before you can see something in the browser, we need to get the Software running, otherwise you will see the well known message.
I need a log. Please try to attach the whole log file.
Got the SSH to work using PuTTY. Below is the contents of the fabscanpi.log file from the "/var/log/fabscanpi/" location, not much there, I hope this helps, let me know what other files you need.
I ran the “PS” command and everything looks as per the browser screen except the number after of the “root” is a lot smaller (~700). I tried to restart the fabscanpi service and I get a error the service is not found.
I hope this helps, looking forward to your thoughts!
Interesting that the fabscanpi service is named "fabscanpi-server" not just "fabscanpi" as per the default web page as per below. Also, I can start and stop the "fabscanpi-service" as you would expect.
You might also want to try if you can restart the server (if no obvious error is visible): sudo service fabscanpi restart.
Yes, the Service was always called fabscanpi-server. This is because the fabscanpi project consists of different components.
the fabscanpi-fontend
the fabscanpi-server
the FabScanPi image
the fabscanpi-firmware
By the way systemd is still not supported for starting and stopping services. There is already an issue on GitHub for introducing systemd. It is on the top of the upcoming feature list.( https://github.com/mariolukas/FabScanPi-Server/issues/138 )
Anyway you can start/stop/restart the service by running:
If it isn't, the question is why. Take a look into /var/log/fabscanpi/fabscanpi.log, there might be an error logged in there that helps to determine what's wrong.
You might also want to try if you can restart the server (if no obvious error is visible): sudo service fabscanpi restart.
If all that doesn't help to trouble shoot the issue, you can seek support on the https://fabscan.org/%2 2">FabScanPi Community Page. Please provide your Browser version and FabScanPi version as well as your fabscanpi.log and explain what you already tried and observed as detailed as possible.
The last line in the log file after the restart is;
2019-11-28 19:05:49,741 - fabscan.scanner.laserscanner.driver.FSSerial - DEBUG - Trying to connect Arduino on port: /dev/ttyAMA0
Update - New hardware, Fresh SD card Image - Nothing changes. Browser displays famous message and Log ends with "Trying to connect Arduino on port: /dev/ttyAMA0"
Not sure where to go from here - waiting to hear back from you on the next steps.
Not much to add, except that, if I connect a HDMI monitor to the HAT, once the system boots the screen goes blank except for a blinking cursor in the upper left hand corner of the monitor and a blinking mouse pointer (arrow) in the middle of the screen. Mario says this is normal because the user interface is browser based.
Are you seeing this same thing?
Otherwise we are waiting to hear back from Mario on the next troubleshooting steps.
Ok. It is time to discover what is going wrong. First we need to find out if the HAT is able to communicate with the Raspberry Pi. For this you can try the following command after you are logged in on the pi console.
When this does't work try to use 57600 instead of 115200. This command tries to communicate with the atmega ic on the FabScanPi Hat. It should return a that communication was successful. Please post the result of the command. This mostly fails when the bootloader is corrupted or the solder joints on the HAT are bad.
I did as you suggested and the results puzzle me. I attached a file with the results. This log is the results after installing a new image in the SD card and using a clean boot.
I hope this means something to you. As you can see some times the command hung and had to be exited with a control "C".

Well I dis some further testing tonight and think I found out why the "sudo avrdude-autoreset -p m328p -b 115200 -carduino -P/dev/ttyAMA0" command did work all the time. I found that if you stop the service it works fine at both baud rates, see below.
Additionally I tried both baud rates for the Flash and Serial Baud rate, nothing changes I still get the same screen and the Log file looks like this;
2019-12-12 01:34:26,113 - fabscan.server.FSScanServer - INFO - FabScanPi-Server 0.8.0+201911082051 2019-12-12 01:34:26,122 - fabscan.scanner.interfaces - DEBUG - Scanner Type is: laserscanner 2019-12-12 01:34:28,164 - fabscan.scanner.laserscanner.driver.FSSerial - DEBUG - Port in Config found 2019-12-12 01:34:28,168 - fabscan.scanner.laserscanner.driver.FSSerial - DEBUG - Latest available firmware version is: v.20190811 2019-12-12 01:34:30,412 - fabscan.lib.util.FSUtil - DEBUG - avrdude-original: Using autoreset DTR on GPIO Pin 7 2019-12-12 01:37:53,202 - fabscan.lib.util.FSUtil - DEBUG - avrdude-original: Using autoreset DTR on GPIO Pin 7 2019-12-12 01:37:53,763 - fabscan.scanner.laserscanner.driver.FSSerial - DEBUG - Trying to connect Arduino on port: /dev/ttyAMA0
I also attached some more log files for your review. Lots of errors relating to - "lightdm[2952]: Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Accounts was not provided by any .service files"
Of course. That was my fault. The serial port is blocked when the Server is running. But it is good to see that the serial connection is working. Now we can be sure that the HAT is ok so far. I think a next step would be trying to flash the firmware directly by using avrdude. But before we do that, can you provide the full FabScanPi.log file again. I just want to be sure.
OK, sounds good, attached are the files you ask for.
The log file looks strange for me. I do not have an idea what is going on there. But i also discovered that there are services running which are not contained in the ready to use fabscanpi image like
And after you installed it please try to start again. Please do not install any additional packages. We really need to have a plain state to start our investigation. I think you should also attach the fabscanpi.log again after you started the fresh installaiton for the first time.
What you say makes sense and was why I was asking about "raspi-config" and how to configure to boot selections. When I switch raspi-config to "Desktop mode with auto login" (see image attached), the pi asks me to install other software, of which lightdm is part of. If I do not do this when the PI boots it goes into SSH mode on the HDMI / Keyboard setup attached to the PI directly. If I switch to "Desktop with Autologin", the PI boots to the screen we have talked about in the past (Cursor in upper right hand corner and mouse pointer in the middle - both blinking).
Is this wrong?
If you have any input on this it would be appreciated, I will also start a fresh SD card and boot it.
In the mean time Please let me know what you think.
As per your request. The log file is quite short and is attached I also attached the output of ps -axf command. I am now in SSH mode via PuTTy and direct connection, no flashing cursor screen. I attached a photo of what the direct connect (HDMI) screen looks like also.
I have been researching this issue and have found some more information, which lead to more questions ? .
In the documentation there is a reference to using "Bonjour" for a windows PC, I am using Windows 10 and have tried Chrome, IE and Edge as the browser, do we still need Bonjour?
There is also a reference to the name of the javascript configuration file (see below), is the correct file name "default.config.javascript" or "default.config.json"?
I also found the Boot Loader test on the Wattrerott web page and they say to use the -v switch also (see below), but don't say what the expected out come should be.
I attached the output of this command with the -v switch added, the output is the same for either baud rate, just changes the rate in the report. Hope this will lead us to the answer!!! ?
I hope this isn't too many questions at once and thanks for you support.
