Hi,
i am trying to install under Linux-Kernel 3.2.0 the drivers of the can - usb interface. I'm following the instruction here
http://www.peak-system.com/fileadmin/me ... ng_7.x.pdf indicated.
when i do make in the main directory i get
Code: Select all
src/pcan-settings.c:50:18: fatal error: popt.h: No such file or directory
. After some searching i found out that i have to compile in the "driver" directory.
After that, when i do
i get
.
what am i doing wrong?
thx
Matteo

Hi,
please send output of cat /proc/pcan, looks like you have compiled the driver for netdev but you use the chardev tools.

Hi,
looks ok, it is compiled for chardev. Did you use a terminated CAN cable, and does your other CAN node tranmsit at 500k?

hi,
after the pcan-usb converter i just used an adapter to solder the cables of my device (cable lenght ca. 62cm)...not sure whether it is the answer you expected
no, the device is transmitting at 1Mbps (CAN Bus 2.0B).
cheers

Ok,
than you have to call echo "i 0x0014 e">/dev/pcan32 to set the baudrate to 1Mbit and enable ext. frames, and put two 120 Ohms resistors between CAN-H and CAN-L on both ends of your CAN cable, to let things work.....is this your first application with CAN?
