====== Unipi Software ====== This article includes topics related to Unipi software (repository, FW tools, etc.) ===== APT Repository ==== All tools are distributed via a Debian package repository available at https://repo.unipi.technology/debian/ The APT repository is already preconfigured in our [[files:software:os-images:00-start|official images]]. Currently, the packages are supported only for all units except Unipi 1.1 and Unipi 1.1. lite - those should be [[en:sw:02-apis:01-evok|installed as described here.]] To install the tools to a clean Debian/Raspbian system, follow the steps in the README file located in the repository https://repo.unipi.technology/debian/README.apt Developmnent & Testing versions Our tools are also distributed in testing/development versions. If you wish to install those, find the exact package at https://repo.unipi.technology/debian/pool/test/ and just put it's whole name without the suffix, e.g. _arm64.deb, in the //apt install// command. Be aware that any package in the testin pool might break things. ===== Application interfaces ===== Available APIs are described in the [[en:sw:02-apis:01-evok|SDK section]]. ===== Firmware ===== Firmware (the Software running within the Hardware) is a big part of our hardware (except Unipi 1.1) and gets updated during the time as things are getting fixed or new functionality is being added. The Firmware is a standard part of our OS images and is also distributed in our repository in the unipi-firmware package. The internal firmware is NOT automatically flashed to the latest version installed using apt. This has to be done manually. === Upgrading firmware in Patron/Neuron/Axon line units === The firmware can be manually upgraded or checked using the fwspi tool which resides in /opt/unipi-bin/ (newly in /opt/unipi/tools/). To check the firmware on the first section of IOs: /opt/unipi/tools/fwspi -i 0 To check the FW of other IO sections run /opt/unipi/tools/fwspi -i 1 alternatively /opt/unipi/tools/fwspi -i 2. Firmware upgrade can be done automatically on all sections available using command /opt/unipi/tools/fwspi -v --auto == Online firmware installation == * 1. Obtain the latest firmware version apt update apt install unipi-firmware * 2. Check the current FW version installed in the HW /opt/unipi/tools/fwspi -i 0 * 3. Update to the latest obtained FW version /opt/unipi/tools/fwspi -i 0 -P * 4. Re-check the current FW version installed in the HW /opt/unipi/tools/fwspi -i 0 == Offline firmware installation == Online installation is always preferred because the firmware package can have other packages are dependencies (such as firmware-tools, kernel driver, ...). Please always use the online installation. * 1. Download the latest version of the **unipi-firmware** package from https://repo.unipi.technology/debian/pool/ Then it is needed to get it to the unit. There are two ways to do that: * 2.a - Using SCP * Copy if from your PC to the unit using SCP (a WinSCP, Filezilla or other software can be used) to the /tmp/ folder * Install the package using dpkg, for example dpkg -i /tmp/unipi-firmware_5.50_all.deb * 2.b - Via USB flash * Copy the downloaded file from your PC to the root of the FAT32 formated USB flash and insert the USB flash to any USB port of the unit. * Switch to root user sudo su * Find out the name of the inserted flash disk (usually it is //sda1//) fdisk -l * Create a mount folder for the disk mkdir /media/usbflash * Mount the disk to the newly created folder mount /dev/sda /media/usbflash * Install the package using dpkg, for example dpkg -i /media/usbflash/unipi-firmware_5.50_all.deb * 3. Check the current FW version installed in the HW /opt/unipi/tools/fwspi -i 0 * 4. Update to the latest obtained FW version /opt/unipi/tools/fwspi -i 0 -P * 5. Re-check the current FW version installed in the HW /opt/unipi/tools/fwspi -i 0 The configuration of the section can be erased to the default state. This is done during the firmware upgrade by calling the fwspi utility also with -R parameter. E.g. /opt/unipi/tools/fwspi -i 0 -PR === Upgrading firmware in RS485 Modbus extensions === xS/xG series extensions can be upgraded similarly. Instead of **fwspi** utility, just use the alternative named **fwserial** which is also included in the //unipi-firmware-tools// package (installed automatically with //unipi-firmware//). The command-line arguments are very similar as for the fwspi, except serial port specification. Make sure that there is no other application using/communicating on the used port and do not disconnect power to the unit or Extension. Any of this will lead to bricking the extension. The -p (path) parameter must be set according to the used serial for the extension - see the [[en:hw:007-patron:portmap|]], [[en:hw:02-neuron:portmap|]] or [[en:hw:01-axon:portmap|]] to find proper serial port within your unit. For example, if extension is connected to //RS485-1/RS485-1.1//: /opt/unipi/tools/fwserial -p /dev/ttyNS0 -P . Note that the fwserial assumes that extension‘s Modbus address, baud rate and parity are in the factory-default state, ie **19200 baud 8N1 with address 15**.
