Can't load 2nd CAN port in device
Posted: Fri 19. Nov 2010, 13:48
I have an embedded system with one on board CAN port and once PCAN-PC/104 Single Channel opto-decoupled CAN port. When I try to load the linux driver I only get one port activated. I am using linux driver version 6.7. I have already verified the operation of each CAN port individually. I need them to work simulatenously. Can anyone help?
PCAN-PC/104 serial number: IPEH-002056 00932
driver load commands:
/sbin/insmod /lib/modules/2.6.17.13inc70/misc/pcan.ko type=isa io=0x340,0x300 irq=5,7
/usr/sbin/pcan_make_devices 2
results from /var/log/messages.log
