Banana Pi BPI-R2 Razberry board OpenHab2 - help!

Setup, Configuration and Use Installation
1

Hi all,

So I decided that the BPI-R2 would make a nice OpenHab machine.

The Razberry 2 is on the GPIO pins as you would expect.

I’m running - 2017-09-14-raspbian-stretch-preview-bpi-r2-sd-emmc.img - which is stable.

  • I’ve updated java :java -version
    java version "1.8.0_131"
    Java™ SE Runtime Environment (build 1.8.0_131-b11)
    Java HotSpot™ Client VM (build 25.131-b11, mixed mode)

  • I’ve installed Openhab2 and appears all good and stable. Use Raspberry instructions with apt-get

  • I’ve amended my /usr/share/openhab2/runtime/bin/setenv to include the -Dgnu.io.rxtx.SerialPorts entry

  • I’ve added the same to /etc/default/openhab2 EXTRA_JAVA_OPTS

  • I’ve used raspi-conf disable remote access to serial while leaving it enabled.

  • There is a setting about GPIO being accessible over the network - I’m not sure on this one, anyone?

  • Able to add the appropriate “add-ons” and Things in paper ui but the Z wave shows as offline,

  • /var/log/openhab2/openhab2.log just sits there " Connecting to serial port ‘/dev/ttyS1’" and doesn’t go any further.

  • The /boot/config.txt enable_uart=1 is there. As far as disabling wifi and bluetooth those are platform specific and I’m not sure if anything equivalent if required.

  • /boot/cmdline.txt all looks ok, I didn’t have to remove anything but please confirm:

dwc_otg.lpm_enable=0 console=tty1 console=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

  • The openhab user has been added to the appropriate tty and dialout groups.

  • The BIG question is what port device to use, /dev/ttyAMA0 or similar doesn’t exist and online i see people using /dev/ttyS1 ,2, 3 etc… I’ve tried them all. Can anyone confirm what they’ve done? or how to tell what port I should be using? a ls -l /dev/tty* confirms that ttyS1,2,3 is prob the way to go. I’ve tried them all. I’ve repeated the add-on and thing installation with a reboot after changing the setenv etc, each time,

(btw I’ve tested the Razberry on a raspberry pi with Razberry image and it works fine.)

  • Should I be using a different OS?

  • Can anyone who has had success with this confirm: the port, the raspi-config settings, anything that needed disabling and how, or the OS they used.

  • I’ve not run any of the prepare scripts as they are all raspberry centric and look for /dev/tty/AMA0 etc

This is driving me nuts and really would appreciate any advice.

Thanks

As a first thing, there should be no need to edit /usr/share/openhab2/runtime/bin/setenv, the settings in /etc/default/openhab2 should suffice.

In question of the correct tty, take a look at the output of

ls -l /dev/tty*

On a common PC platform, typically there are two serial interfaces named ttyS0 and ttyS1. On a Raspberry this would be ttyAMA0. If using an USB interface (like a zwave stick), it could be ttyUSB0 or something else, so you have to get this information.
As you can use a Raspberry headless, the serial interface is normally configured to be bound to the kernel console (this is switched off by raspi-conf, but I don’t know if this will work at the Banana Pi as well, maybe the command will differ. The /boot/cmdline.txt should not contain console=/dev/ttyAMA0 if this is the serial interface.

As I neither own a Banana Pi nor a Razberry, I searched a little bit and got this https://forum.z-wave.me/viewtopic.php?f=3422&t=21064 so it seems, the name of the razberry interface should be /dev/ttyS2. So this should belong to the dialout group (and permissions set to something like 660). This interface must be set in /etc/default/openhab2 and also in the zwave configuration of openHAB2.

Hey buddy, thanks for getting involved!

Firstly as you can see in the output (bottom of post) you can see the ttyAMA0 doesn’t exist on the Banana, permissions look ok. I have tried ttyS2 before - in fact i did see that doc before.

Can you just confirm in its entirity what the cmdline.txt should be - just to avoid confusion, do i drop the baud as well for example?

I’ll set the port in openhab2 only. Thanks,

In terms of raspi-config. I get the options:

For Serial:

Would you like a login shell to be accessible over serial? yes/no
Would you like the serial port hardware to be enabled? yes/no

Remote GPIO:

Would you like the GPIO server to be accessible over the network? yes/np

Here are all the nterface options:

P1 Camera Enable/Disable connection to the Raspberry Pi Camera
P2 SSH Enable/Disable remote command line access to your Pi using SSH
P3 VNC Enable/Disable graphical remote access to your Pi using RealVNC
P4 SPI Enable/Disable automatic loading of SPI kernel module
P5 I2C Enable/Disable automatic loading of I2C kernel module
P6 Serial Enable/Disable shell and kernel messages on the serial connection
P7 1-Wire Enable/Disable one-wire interface
P8 Remote GPIO Enable/Disable remote access to GPIO pins

What do you think they should be.

As I don’t own a Banana Pi, I don’t know what the cmdline.txt should look like, but of course the baud rate is part of the console definition.
As there are 4 serial consoles (and one for tty), let’s try another thing.
First shutdown the system and disconnect Razberry. Start the Banana Pi and list the serial consoles with

ls -l /dev/ttyS*

If the list is one console short, this should be the Razberry. Additionally, you could use

dmesg | grep -i -A1 -B1 ttys

this should throw 3 lines for each serial interface and you should see the hardware it belongs to.

No difference from ls /dev/ttyS* (with device unplugged ) :crw–w---- 1 root tty 4, 64 Dec 12 23:43 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 Dec 12 23:43 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 Dec 12 23:43 /dev/ttyS2
crw-rw---- 1 root dialout 4, 67 Dec 12 23:43 /dev/ttyS3

dmesg | grep -i -A1 -B1 ttys: again nothing interesting.(board was plugged in at this point)

Is it for sure that the /dev/ttySx device would disappear once the device is removed?

I;vr never run any driver or tool from the Razberry site : is this required? Its only serial right?

Thanks for your help again

I’m wondering a) 2A is enough power for the device and Razberry2 board or b) Proper GPIO support somehow isn’t right in this preview: 2017-09-14-raspbian-stretch-preview-bpi-r2-sd-emmc.img

If you check here: https://drive.google.com/drive/folders/0B_YnvHgh2rwjTkdwNnE2VmFoNzg

The best most stable image around is Ubuntu 16.04.

As I don’t own a Razberry, I can only guess. Maybe you have to install the zwave server:

wget -q -O - razberry.z-wave.me/install | sudo bash

but as mentioned, this is just a guess.

I got this working in the end.

Basically you need to enable the GPIO by amending the appropriate dts files in the kernel code ( https://github.com/BPI-SINOVOIP/BPI-R2-bsp ) and setting the uart entries to “status=okay”

detalled here:
http://fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:gpio

Then compile the kernel (in a VM or whereever) and ship it over to the BPI-R2 SD card.

The good news is there is two other options:

  1. frank-w has got pre compiled kernels here, I used 4.4.108. https://drive.google.com/drive/folders/15Y5Y3NAOwg_IMmN3k6hdb7pAQj9oTVTl . just copy over the BPI-BOOT and the BPI-ROOT over to the appropriate partition mounted on other machine as root!

  2. If you prefer 4.14 with uart/gpio enabled in preconfgiured debian images, frank-w has done those too: https://drive.google.com/open?id=15Y5Y3NAOwg_IMmN3k6hdb7pAQj9oTVTl

After than just follow the install. use /dev/ttyS2 . make sure setenv and openhab/default have the appropriate entries.

Make sure openhab is added to the tty group.

Sort java out etc…

Good to go - it works well.

Just to confirm in point 1 I’m using the Ubuntu 16.04 image, not the rasbian stretch preview I was using earlier.
