CAN
Connect CAN0 with CAN1 by connect Pin 33 to Pin 34, Pin 35 to Pin 36 in J9.
Test method as below:
1. Open CAN0 CAN1
root@embest:~# ip link set can0 type can bitrate 50000 triple-sampling on
root@embest:~# ip link set can1 type can bitrate 50000 triple-sampling on
root@embest:~# ip link set can0 up
flexcan 2090000.can can0: writing ctrl=0x27292085
root@embest:~# ip link set can1 up
flexcan 2094000.can can1: writing ctrl=0x27292085
2. Send and Receive
CAN1 receive data, CAN0 send data to CAN1, if the following info printed, the test passes:
root@embest:~# candump can1&
[4] 589
root@embest:~# cansend can0 123#01020304050607
can1 123 [7] 01 02 03 04 05 06 07
Use show command to check the status of CAN.
CAN0 Tx added 1 packet, 7 bytes. CAN1 Rx added 1 packet, 7 bytes.
