HI!
We are trying to set up a system which uses RTLinux for collecting
data. This box needs to communicate via CAN. I found a few CAN-drivers
and tried to compile them. No luck so far!
Question 1:
Using Heinz Haeberle can driver, I get complains RTL_SPIN_LOCK (see
below). Anyone knows about this?
Question 2:
I am not sure wether I need to have SMP enabled in the kernel or not
(?) Could a wrong setting cause the above RTL_SPIN_LOCK-error
Question 3:
Can anyone recommend a driver that
- suits our system (see below)
or
- os known to be "good"
Our system:
