HM-MOD-RPI-PCB and OCCU with Pi3

Beitrag von bosschaert » 31.01.2017, 22:32

Hi all,

I have the HM-MOD-RPI-PCB with OCCU working fine with my Pi2 (I posted the steps for that a while back here: http://homematic-forum.de/forum/viewtop ... 64#p278958 )

Now I wanted to set up another Pi with another HM-MOD-RPI-PCB and OCCU. This time I got a Pi3. I have installed HM-MOD-RPI-PCB with OCCU exactly the same way but it does not get recognized by the Pi3. When I look at the startup log I see the following messages:

Code: Alles auswählen

Jan 31 21:57:16 top rfd: No BidCoS-Interface available
Is there anything that I should do differently for the pi3 or is there anything else that I might need to do to get the Pi3 to talk to my HM-MOD-RPI-PCB?

(PS I tried the HM-MOD-RPI-PCB board on my Pi2 and it works there)
(PS2 replies in German is fine :)

Hmmm, it seems like this forum is not as vibrant as it was before, but I think I got past the issue described above. It seems like the Bluetooth functionality that comes with the Pi3 by default got in the way. I added the following to the config.txt to fix this. This is basically what is in the config.txt that comes with RaspberryMatic:

Code: Alles auswählen

dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=spi=on

# enable the UART
enable_uart=1

# make sure the uart is running at 48MHz
init_uart_clock=48000000

# disable the bluetooth UART use and
# disable the uart1 alltogether
dtoverlay=pi3-disable-bt
dtparam=uart1=off

# disable the splash screen
disable_splash=1

# activating the hardware watchdog
dtparam=watchdog=on
I also changed cmdline.txt to the following (not sure if this was necessary):

Code: Alles auswählen

dwc_otg.lpm_enable=0 console=tty2 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
