We started to work with new OS release which claims to support CAN bus.
But it seems to not work.
We are trying to send something.
ip link set can0 type can bitrate 1000000 ip link set can0 up cansend can0 -i 0x1F 0x11 0x22 0x33 0x44 0x55 0x55 0x77 0x88
cansend can0 01A#DEADBEEF
And we cannot receive any data using USB-CAN adapter. Also we have tried to receive data using
This results in nothing but:
interface = can0, family = 29, type = 3, proto = 1
We have tried several bitrates (125000, 10000 etc.) with same result.
The oscilloscope shows the same picture regardless bitrate and data sent (see below). Channel 1 is CAN-L and channel 2 is CAN-H. The frequency (ca. 30 kHz) is quite strange. The pattern doesn’t change while various data is transmitted.
