RaZberry 7 Pro serial problem RPI4b bookworm

[p_kay_hart]

I'm running z-way-server on a Raspberry Pi 4b bookworm. My controller is a RaZberry 7 Pro. US. The serial port is set to /dev/ttyAMA0. I've checked all of my location settings on the Pi and the Time zone in the z-way server settings. All are correct there. When connected to the web interface I often must reload the page to get past the error indicating a serial port communications problem but data does get saved. Obviously there is a problem with my serial connection to the controller. I purchased another RaZberry 7 pro on the chance that I had damaged the original one but they both seem to have the same problem. In expert mode the reset API action always results in the error "Unable to update data. SerialAPISoftReset()". I have tried several power supplies on the Pi4. Same response. I have rebuilt the server a couple of times with the same end result.

Can anyone point me to a possible solution or suggest where else to look?
Thanks very much. full z-way-server.log following a re-boot is attached

What does the end of the Pi configuration look like?

/boot/config.txt

[p_kay_hart]

Hmm. Must have hit the wrong button. If this is a duplicate reply, my apologies..

# Run in 64-bit mode
arm_64bit=1

# Disable compensation for displays with overscan
disable_overscan=1

# Run as fast as firmware / board allows
arm_boost=1

[cm4]
# Enable host mode on the 2711 built-in XHCI USB controller.
# This line should be removed if the legacy DWC2 controller is required
# (e.g. for USB device mode) or if USB support is not required.

FYI - I'm not sure why the seemingly conflicting bluetooth settings but I've spent a lot of time trying to get an HDMI output that would work with a KVM I use. This Pi4 B is in an Argon One M.2 case and I boot from an internal 500 GB SATA SSD. I've checked the power and that all seems fine. I'm confident that the RaZberry 7 Pro is connected to the GPIO pins of the Argon case correctly but if I don't get anywhere with the RaZberry controller my next step will be to remove the Pi from the Argon case and attach the controller directly to the GPIOs of the Pi board and re-configure my boot drive into an external case. I have 4 other Pi4s working well that way.

Thanks for responding lanbrown

HI,

try to modify the config.txt (at f=/boot/firmware/config.txt ) :

Code: Select all

...
[all]
dtoverlay=pi3-disable-bt
enable_uart=1

If it does not help use raspi-config to disable the not needed options.

It Works!

Remove the Pi4b from its Argonone case after cloning the internal M.2 SATA drive to an external USB SATA. Uninstalled the Argone software. The Pi4b now sits on an open air enclosure with a fan and a Dual header on the GPIOs to accommodate the RaZ 7 Pro and the fan leads. External drive is powered by a USB 3.0 hub. The Pi runs cooler outside of the Argon M.2. used your config.txt suggestions although I believe I had found these entries and tried them before but they certainly work. I may have had some odd conflicts due to the Argon case. Can't recommend it for this application. It all worked fine under bullseye but with bookworm and the Wayland stuff, things seem to have changed.

Thanks Michael.

If you really want to have your Pi run cool, get a silicone thermal pad and the Geekworm for Raspberry Pi 4 Armor Case. Put the silicone pad on the top and bottom of the board (you will need to cut to fit) and your Pi will never overheat even if running at 100% CPU load. No fan needed either, all passive cooling.

I will check that out Thanks.
