with these dip-switch settings:
Dip-switches on modules:

xS50 #1 = 1 0 0 = EXTENSION_1, address = 1
xS50 #2 = 0 1 0 = EXTENSION_2, address = 2
xS50 #3 = 1 1 0 = EXTENSION_3, address = 3

Please note they are al on the first UART: 1.1 - RS485. Does that make a difference?

p.s. I used a default Raspbian stretch image (so not one of you're images), and used your install scripts like so:

sudo su
wget https://github.com/UniPiTechnology/evok/archive/v.2.0.7.zip
unzip v.2.0.7.zip
cd evok-v.2.0.7
bash install-evok.sh

Is that any problem?

Martin Kudláček

Let's investigate:

Did you restart the Neuron after changing the settings (or at least the evok service)?
what Raspbian image do you use ? Please, paste the output of the uname -a.
~~We are probably (not confirmed, working on it) experiencing an issue with running the EVOK on the up-to-date Raspbian~~

@martin-kudláček

Yes; I'm very neurotic on that, I rebooted the L513, and made the extensions powerless also.
As for the version, I'm using the latest Debian, (downloaded it from the website last week?):

Linux raspberrypi 4.14.50-v7+ #1122 SMP Tue Jun 19 12:26:26 BST 2018 armv7l GNU/Linux

Martin Kudláček

That seems to be OK. I will have to reproduce your setup, but I'm not sure, if I will be able to make it today. Tommorow morning for sure.

Martin Kudláček

OK, I partially reproduced your setup. I have:

Neuron L503 with latest, up-to-date Raspbian (Linux raspberrypi 4.14.52-v7+ #1123 SMP Wed Jun 27 17:35:49 BST 2018 armv7l GNU/Linux), and EVOK 2.0.7. Serial line 1.1 configured with 19200bps, 8N1:

One extension xS40 with address 3 (DIPs 3 and 4 are down):

Another extension xS50 with address 2 (DIP 2 is up):

Can you check your setup against mine above? Try simplifying the extension's configuration as I did.

salorob

I wil have to check in a minute.
As far as I can remember from testing yesterday; even if I connect just 1 module, which I give a fixed address with the dipswitch (say; dip 1 = up, makes address = 1 (right?)), and configure the evok.conf accordingly, it won't work.

So in my opinion, setting an address manually by dip-switch, causes something to go wrong. Either I don't understand how the dip's represent an address, or something else goes haywire...

however; I didn't check with the ;neuron_uart_circuit = 1_01 commented like in your example, wil check that in a minute.

What does this option do anyway ?

salorob

So; another quick test:

If I connect just 1 xS50, which I give a fixed address with the dipswitch (dip 1 = up, makes address = 1 (right?)), and configure the evok.conf accordingly, and configure the serial speed, it won't work.
All dip's down, on evok address 15, it works.

Martin Kudláček

Hi,
this really seems to be an issue on our part, probably related to the firmware of the extensions. You are not the only one having the exactly same problem (see https://forum.unipi.technology/topic/652/how-to-add-xs40-to-neuron-l203-using-custom-software/42). We will investigate it a bit more and let you know as soon as possible.

Thank you for your patience,
Martin

salorob

Ah.. okay. Well, at least I'm not crazy.
Please let me know, I need to get this setup running asap.

Thanks!

Martin Kudláček

Hi,
ok, to get your setup running ASAP - would it be possible to use Teamviewer or direct SSH to the controller so we can check what's happening? We will check the extension's firmware version and do the FW update if neccessary.

The best time would be between 12:00 and 20:00 CEST.

Thanks,
Martin

salorob

I can give you ssh access ? please mail me at robert at ropesolutions.nl, I will supply you the details.

Martin Kudláček

@salorob I just sent you the mail.

bsc101

@martin-kudláček Just a quick question, since I also do have this problem with my xS50: Will there be some easy way to upgrade the firmware of the extension? What is the procedure of updating the firmware? Thanks for your answer!
Regards,
Boris

Martin Kudláček

@bsc101 The way to check and update the firmware is fairly easy - just connect the extension via RS485 to the controller, ssh into the controller and run a program. I will write down a tutorial how to do so. We just want to be extra sure, that this problem is tied down to the extension's firmware. I do apologize for this incovenience.

bsc101

@martin-kudláček Sounds good, thanks for your efforts!

Martin Kudláček

Ok, the issue is definitely with the extension firmware 5.6. The current version is 5.18 and for some reason, both of you received extension units with the old firmware... We do apologize for this, if it is even possible.

The @salorob was able to flash the firmware by his own via our Windows application tool. Unfortunately, the tool is also long time waiting for the update, so the firmware version in this tool is only 5.9, instead of 5.18.

So the official hacker's tutorial is:

SSH into your controller, the user "pi", the password (if not changed) is "raspberry". If your image is Raspbian, you need to install additional packages:

pi@raspberrypi:~ $ sudo bash
root@raspberrypi:/home/pi# echo "deb https://files.unipi.technology/debian stretch main" > /etc/apt/sources.list.d/unipi.list
root@raspberrypi:/home/pi# wget -O - https://files.unipi.technology/debian/unipi_pub.gpg | apt-key add
root@raspberrypi:/home/pi# apt update
root@raspberrypi:/home/pi# apt install -y neuron-firmware neuron-modbus-tools

Connect the extension to the controller over RS485. If you have multiple extensions, connect only one at a time. Right now, all of them thinks they have address 15, so you need to avoid collisions.
Confirm, you have a connection to extension

root@L503-sn101:/home/pi# /opt/neuron-bin/fwserial -p /dev/extcomm/0/0 
Boardset:     5 E-14Ro_P-11DiR485              (v1.0)
Baseboard:    2 E-14Ro                         (v1.0)
Firmware: v5.6
Modbus timeout set

Flash the firmware

Page written OK.

Programming page 01 ...Finished programming chunk 0, ret: 64 err: 0
..........

Verify the firmware. Since the flashed firmware now accepts address set by DIP switches, you need to specify the address in the parameter -u. My extension has address 3

root@L503-sn101:/opt/fw# /opt/neuron-bin/fwserial -p /dev/extcomm/0/0 -u 3
Boardset:     5 E-14Ro_P-11DiR485              (v1.0)
Baseboard:    2 E-14Ro                         (v1.0)
Firmware: v5.18
Modbus timeout set

Repeat the process for all of the extensions

Let me know, how it worked. If you don't want to flash the firmware yourself, let me know and we can arrange some remote session with you.

Thanks,
Martin

bsc101

@martin-kudláček Thanks a lot, it works now :) I can set another address than default now!
Firmware is now 5.9 (it was 5.6 as you said), is there any need to upgrade to 5.18?

Martin Kudláček

@bsc101 So I guess you used the Windows firmware update tool as @salorob. There are definitely a bugfixes from version 5.9 with some new functionality as well. You have the tutorial above, so you can update it, if you find out you need it.

@martin-kudláček My fault, did not do step 1 in your decsription above since fwserial and firmware files were already present. It's 5.18 now, thank you!
