Hello everyone,
I am trying to install Xenomai with Soc based on ARM64 and
running it on qemu-system-aarch64 ipipe/xenomai.
I am facing problem while trying to boot it with smp support(multi core)
and using following ipipe and kernel version:
- ipipe: ipipe-3.18-arm64
- Kernel: 3.18
And when trying to launch qemu with the following command:
qemu-system-aarch64 -M virt -cpu cortex-a57 -kernel -smp 4 Image -initrd
rootfs.img.gz -nographic -append "console=ttyAMA0 root=/dev/ram
rootfstype=ramfs init=/bin/sh" -snapshot
I am getting the below Kernel Panic:
...
