Latest Update: Issues with unipi_tcp_server and unipispi

knebb2

Hi,

since the latest update (unipi-kernel-modules-dkms 1.36) I am having issues with my Neuron M103.

Starting the tcp-server manually results in an error about /dev/unipispi:

root@zentrale:/heizung/src# /opt/unipi/tools/unipi_tcp_server -p 502 -l 0.0.0.0  --verbose --check-firmware
ARMINIT: Cannot open device /dev/unipispi
ARMINIT: Cannot open device /dev/unipispi
ARMINIT: Cannot open device /dev/unipispi
UniPi TCP Modbus Server: Listening Connection Established RET:3
poll timeout = -1[ms]
Starting primary loop

When trying to access through modbus I get an error:
fieldbus_get_ai error: Slave device or server failure

So looks like I can not open unipispi device. Modules seems to be loaded:

root@zentrale:/heizung/src# lsmod| grep unipi
rtc_unipi              16384  0
root@zentrale:/heizung/src# lsmod| grep spi
spidev                 20480  0
spi_bcm2835            20480  0

Anyone having a clue how to deal with this issue?

Thanks a lot!

Hi,

I fixed it by
apt install neuron-kernel

It uninstalled dmks modules- I am unsure if this is a proper solution. At least it seems to work now.
