Re: [seL4] x86 Bootable USB install

Hi, Above steps given by Peter Chubb worked fine. I was able to get the output through serial port. But it executes the test suite and then stops. How can I get a shell prompt so that I can test the kernel for virtualization? My question may be completely wrong here but I'm new to this field. How can one use seL4 kernel to install virtual OS on top of it on x86 architecture? On Fri, Sep 5, 2014 at 5:10 AM, Peter Chubb wrote:

If you have built a seL4-based systemaccording to the instructions, the kernel and root server are in .../images/ They have different names according to what you've built.

For example, sel4test names the root server sel4test-driver-image-ia32-pc99 and the kernel kernel-ia32-pc99

I generally use syslinux to create a bootable USB stick, as the grub on my system wants to use EFI.

Like this, assuming your flash drive is at /dev/sdb with a FAT partition at /dev/sdb1:

install-mbr /dev/sdb syslinux --install /dev/sdb1 mount /dev/sdb1 /mnt cp images/sel4test-driver-image-ia32-pc99 /mnt/rootserver cp images/kernel-ia32-pc99 /mnt/sel4kernel cat > /mnt/syslinux.cfg <

use fdisk to make sure the first partition is bootable.

And you're done. Output will come on the serial port
