For example, you can configure the CAN device by setting the bit-timing parameters via the netlink interface using the program ip from the iproute2 utility suite. The following changes are needed for the device tree: Let us know in the comments, or contact us to talk more about how Opal-6 could help you take the hassle out of your new product development. Setting the bitrate Before you can start the CAN network device, you must configure the bitrate at which it will communicate, for example: Use the latest kernel sources as we had to backport the following commits:

Flexcan net device driver
Fflexcan example, you can configure the CAN flexca by setting the bit-timing parameters via the netlink interface using the program ip from the iproute2 utility suite. Eric evenchick is an embedded systems developer with a focus on security and automotive systems. See also the CAN integration commit on git. The syntax of the cansend command is different between the two. Hello, im running the neo end of october beta image, which has nwt arduino ide that programs the blink example of the cortexm nicely, and i see that the flexcan kernel module is built and included so i gave it a shot.
For more information, see the Linux kernel documentation: The most important configuration is the bitrate. The best new feature is support for a splash screen on boot.
Hi, this patch adds support for the freescale flexcan can controller. This is very simple to use — just pick an image and download using the updated Topaz Flasher.
Meanwhile, the official linux repository has device drivers for all major. 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. Before you can start the CAN network device, you must deivce the bitrate at which it will communicate, for example:.
Kernel versions prior to 4. If your products interface to other devices using RS, then getting everything talking with Opal-6 will be easy.
het Hello, sorry for the confusion about the last minute problem with the driver, it was false alarm. Syntax To display the application syntax: When it comes to software, the Linux driver takes care of managing the transmit enable line. Note that the canutils come in two flavours, one provided by Pengutronix and a fork thereof, currently hosted at https: The following shows the bring-up of a Colibri EvalBoard V2. Refer to this hardware related dsvice. Support for coldfire is missing though at the moment as they have an older revision of the core which does not have rx fifo support.
The following changes are needed for the device tree: Change the status of the mcpcan node to okay and add a status property to the spidev1 node which is disabled. The maximum message buffer is In the following example, X is the index of the CAN node you want to bring up or flexccan.
Flexcan on i.mx536 Infotainment Platform
RS is also supported in Windows Embedded Compact Devcie using this configurations, the platform data for the SPI resp. Socketcan the official can api of the linux kernel. In the original driver, the clock was requested without specifying the connection id, further all mainline arm archs with flexcan support imx28, imx25, imx35 register their flexcan clock without a. It has CAN transceivers on-board, and push-wire connectors so you can get developing fast.
Both can be built with openembedded, the former with devvice canutils’ and the later with ‘bitbake can-utils’. We have customers using CAN for a wide variety of applications.

The CAN interfaces are defined in the i. Once the device tree is setup to use a CAN device, the modules will get loaded automatically.
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.
