Tested on Debian/GNU/Linux for SJA1000 and CTU CAN FD
QEMU=/home/pi/repo/qemu/qemu-build/qemu-system-x86_64
$QEMU -enable-kvm -kernel $KERNEL \
-m 512M \
-initrd ramdisk.cpio \
-virtfs local,path=shareddir,security_model=none,mount_tag=shareddir \
-vga cirrus \
-append "console=ttyS0 \
-object can-bus,id=canbus0-bus \
-object
can-host-socketcan,if=can0,canbus=canbus0-bus,id=canbus0-socketcan \
-device kvaser_pci,canbus=canbus0-bus \
-device ctucan_pci,canbus0=canbus0-bus,canbus1=canbus0-bus \
-nographic
By the way, I would like to discuse how to update CTU CAN FD a SJA1000
IRQ handling to allow mapping on FPGA target platform buses from command
line.
I have some working prototype
https://github.com/ppisa/qemu/commits/net-can-ctucanfd-platform/
but I have some questions how to implement interrupts processing
(or logic function) correct and acceptable way. I wills tart new
thread and hope somebody responses and teaches me what is the
proper solution.
Best wishes,
Pavel
