Peripheral CAN[edit | edit source]
CAN is routed through the PL using the TCL scripts for the Vivado project example here below:
recreate_prj_bora_BASE.tclrecreate_prj_boralite_BASE.tclrecreate_prj_boralite_NAND.tclrecreate_prj_borax_BASE.tcl
Accessing the peripheral[edit | edit source]
Linux messages at boot time[edit | edit source]
root@bora:~# dmesg | grep -i can [ 0.545770] CAN device driver interface [ 0.752012] can: controller area network core [ 0.761010] can: raw protocol [ 0.763989] can: broadcast manager protocol [ 0.768236] can: netlink gateway - max_hops=1
Enable the interface and check status[edit | edit source]
The following commands can be issued from command line in order to send and receive CAN frames:
root@bora:~# canconfig can0 stop can0 state: STOPPED root@bora:~# canconfig can0 bitrate 500000 can0 bitrate: 500000, sample-point: 0.875 root@bora:~# canconfig can0 start can0 state: ERROR-ACTIVE root@bora:~# candump can0 & [1] 298 root@bora:~# interface = can0, family = 29, type = 3, proto = 1
Usage with can-utils[edit | edit source]
