Hello,

I'm trying to set up the CAN interface on the IMX6 Sabre AI.

I used the tutorial from here: https://community.freescale.com/docs/DOC-1437

But when i try to test the connection with this command:

canconfig can0 bitrate 125000

i get an error "command not found"

i also tried this:

ip link show can

Here "can" can't be found.

Has anyone an idea to resolve this problem??

Please refer to the Chapter 39 "FlexCAN Driver" of the attached i.MX 6 Linux Reference Manual document (this document can also be found in the L3.10.17_1.0.0-GA BSP documentation bundle) for the information on how to make the low-level CAN interface driver up and running on the i.MX6Q SABRE AI board. This is for the latest Yocto L3.10.17_1.0.0-GA BSP release.


Have a great day,
Artur

i tried to build a new image via Yocto. i build base-core-image with iproute2, i2c-tools, libsocketcan and canutils included. On Start-Up there is always a failure "pca953x 2-0032: failed writing register". But on the schematic of Sabre AI i can't se any pca953x Controller. The i2c Portexpanders are max7310!
