IMX6 CAN bus developers guide. Part 1.
IMX6 can bus development guide. CAN bus is popular interface in industrial applications especially in automotive. Schematic inspection and DTS modification. Adding each new hardware interface to image might be started from DTS. Before this you need check what GPIO used by CAN bus in schematic of IMX6ULL SoM (NetSoM) development board.
OpenWrt configuration. Users guide. Part 1. How to configure wifi in STA+AP mode.
Openwrt configuration in wi-fi STA+AP mode to connect to upstream wireless network explained. Based on NetSom and NetSom Development board but might be useful for another devices as common OpenWrt’s LuCi interface used. Main disadvantage of this setup is speed drop twice to end client connected to our AP wireless virtual interfa
openwrt configuration. Users guide. Part 1. How to configure network.
Short topic explaining openwrt configuration to get IP address via DHCP. Explained on example of NetSom development board but suitable for all another OpenWrt driven devices. Initially, fresh built and flashed image won’t get IP address as it configured as DHCP server itself: # ifconfig eth0 eth0 Link encap:Ethe
OpenWrt SoM. Developers guide. Part 1.
Once you decided to use OpenWrt driven NetSoM development board as starting point of development your own custom hardware first of all you should choose one of the available image configuration that feets your needs closely. Full list of available configurations can be found here. Here is simple selection algorithm: All configurations
imx6 som for Network solutions released
After 1.5 years of development process we are glad to inform you that IMX6 SoM for network solutions released. First Openwrt driven industrial grade SoM based on IMX6ULL. Originally developed for internal usage as core processing unit in LoRaWAN gateways we are developing later we desided that SoM we got looks like mature viable stand
IMX6 Ethernet. Development process to add second ethernet PHY IC support. part 3.
In previous chapter we modified DTS to add support for second PHY IC on our IMX6 Ethernet equipped SoM. Time to test it. After compilation of image: $ ./compile.sh flexcan_wifi and updating device firmware: root@OpenWrt:/# scp user@host_address:/path_to_project/lorawan-imx6ull/bin/targets/imx6ull/cortexa7/openwrt-imx6ull-cortexa7-fl
IMX6 Ethernet. Development process to add second ethernet PHY IC support. part 2.
IMX6 Ethernet development process continuation. So after getting working single PHY IC on new revision of OpenWrt driven SoM we continue development process to get working two PHY IC on same PCB. First of all we soldered second testbench that provides access to core functionality (JTAG, both ethernet interfaces and UART console) of So
IMX6 Ethernet. Development process to add second ethernet PHY IC support. part 1.
In last (I hope) revision of OpenWrt driven SoM module we added second ethernet PHY IC to increase functionality of module. Here described IMX6 Ethernet support development process. Support for second ethernet PHY IC to be more precise. Changes made in hardware: shared MDIO interface between two PHY IC (KSZ8081RNAIA); RESET pin routed
SOM based architecture
Two years ago when we started development of LoRaWAN gateway the only starting point that was not in doubt was the decision to use OpenWrt OS. Another requirement was the need to use and industrial grade processor. After many hours of searching we were unable to find such processor we can buy as is and design our […]
Ways to reduce cost of deploying LoRaWAN network
While deploying a LoRaWAN network, an operator is faced with the critical task of breaking the network’s self-sustainability point as soon as possible, when the revenue from providing service by connected end nodes begins to exceed the cost of maintaining the network. Unfortunately, many operators are faced with the fact that te
