Open port RS485
could you please advise me how to open port RS485 (which device)?
I'm running Raspbian with evok installed on it.
While I was running original Mervis image the device was /dev/extcomm/0/0 and there isn't such device.
did you install the latest development version of evok as written in the readme? https://github.com/UniPiTechnology/evok#testing-latest-git-versions
Only that version currently support Neurons.
Yes i did

@tomas254 And what SPI devices do you see in /dev/spi*?
ls -l /dev/spi*
crw-rw---- 1 root spi 153, 2 Feb 8 15:17 /dev/spidev0.0 crw-rw---- 1 root spi 153, 3 Feb 8 15:17 /dev/spidev0.1 crw-rw---- 1 root spi 153, 1 Feb 8 15:17 /dev/spidev0.2 crw-rw---- 1 root spi 153, 0 Feb 8 15:17 /dev/spidev0.3
Try reinstalling the Modbus server as described here: https://github.com/UniPiTechnology/neuron_tcp_modbus_overlay
