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

Can't load 2nd CAN port in device
Re: Can't load 2nd CAN port in device
Hi,
please take care that we do not support "on board" CAN devices from other manufacturer with our linux driver, please read licence informations of our linux driver.
A good working solution will be to use a two channel PCAN-PC104 card IPEH-002057 to have two channels available.
I think we had a similar dicussion about your own isa based hardware some weeks ago. Please be carefull that using an own CAN hardware with our drivers could cause some problems (licence issues and hardware issues!).
best regards
Michael
