IMX6 CAN bus developers guide. Part 2.

Continuation of previous article describing IMX6 CAN bus support implementation. We stopped at manual CAN interfaces configuration and sent test packet between two interfaces. Now is time to automate interfaces configuration process at boot up. Also we want to implement separate OpenWrt config. Let’s call it flexcan_ethernet. Add new config…

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)…

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-flexcan_wifi-squashfs.mtd-sysupgrade.bin /tmp root@OpenWrt:/# sysupgrade -c /tmp/openwrt-imx6ull-cortexa7-flexcan_wifi-squashfs.mtd-sysupgrade.bin check logs first: root@OpenWrt:/# dmesg | grep eth…
