Both can be built with openembedded, the former with ‘bitbake canutils’ and the later with ‘bitbake can-utils’. The best new feature is support for a splash screen on boot. This video has more details, along with a Windows Embedded Compact 7 demo. The patch adds transceiver switch gpio support into flexcan driver, so that platforms that have transceiver switch controlled by gpio can just define property transceiverswitchgpios in their device tree, and then device tree boot just works with it. For example, you can configure the CAN device, setting the bit-timing parameters, via the netlink interface using the program ip from the iproute2 utility suite. Socketcan, the official can api of the linux kernel. Contents [ hide ].

Our last post looked deice CAN bus on the Opal-6 Development Kit and how easy it is to connect to and get a prototype working. MX25 Development Kit image here. In this post, we want to highlight the RS implementation, which also uses the push-wire wire connectors. Once the device tree is setup to use a CAN device, the modules will get loaded automatically.
The managed wrappers support gpio, spi, i2c, pwm and flexcan and come with full source code. When flexcaj comes to software, the Linux driver takes care of managing the transmit enable line.
RS is also supported in Windows Embedded Compact The topaz image binaries and bsps available for download on this page include our standard flexcan driver.
