Hi everybody,
I am actually trying to launch L4Linux on Fiasco.OC+L4RE on Xilinx Zynq using QEMU but I get an error at the end of the boot of L4Linux :
*/bin/sh: can't access tty; job control turned off*
*/ #*
Even if I have a shell prompt I can’t type anything, that’s why I am sending this email.
I am aware that my problem is very similar to this one http://os.inf.tu-dresden.de/pipermail/l4-hackers/2013/005920.html but I tried every solution you suggested.
I am working under *Ubuntu 64bits 14.04* and I am compiling with *arm-linux-gnueabi-gcc 4.7.3*.
To emulate the *Xilinx Zynq*, I’m using *QEMU emulator version 2.0.50* configured this way :
*./configure --target-list="arm-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm*
To launch QEMU, here is my command line :
*qemu-system-arm -M arm-generic-fdt -dtb ~/Documents/zynq-zc706.dtb -kernel ~/Documents/gitL4/l4-hypervisor/build/l4/images/bootstrap.elf -serial mon:stdio*
Zynq is ARM so I’m using this ramdisk :
http://os.inf.tu-dresden.de/download/ramdisk-arm.rd
You can find below my serial output, my modules.list file and my l4lx.cfg file.
Thanks in advance,
Louis.
