Can loopback on Ixora

[Rifo Turs]

Hello,

Following the isoblue repository, I have copied the udev rules and have successfully generated "imp" and "tra" under ifconfig.  I have connected can_H , can_L pins of Canbus 1 and canbus 2.

I tried making a loopback with cansend (via imp) and candump (on tra) but can only get 1 byte of data regardless of what I send.

Did you guys try making a loopback between tra and imp? 

thanks

seems like I used the cansend incorrectly, below combination works fine.


 cansend imp -i 0x18FF2488 0x01 0xFF 0x00 0x10
interface = imp, family = 29, type = 3, proto = 1


root@apalis-imx6:~# candump tra
interface = tra, family = 29, type = 3, proto = 1
<0x488> [4] 01 ff 00 10

Hello Rifo,

The tractor and implement bus on ISOBlue are not set up as loopback interfaces. What do you want to achieve with a loopback between tra and imp?

Hello Yang,

Sorry, I think my wording was not right. I was just trying to test the tractor and implement buses before plugging them into a tractor. So my aim was simply to send from tractor interface and receive from implement.
I am now trying to find a tractor so that I can start testing.


between, how you guys doing? Are there new developments?

Hello Yang,

One more thing, I think both tra and imp interfaces also support loopback.

I have 2 consoles

1)   cangen imp
2)   candump imp

I can see generated messages on candump interface. Is this normal?

thanks
