How to run QNX OS on qemu

#61
Hello,Edgar and Asif, Your discussion is very interesting, I am also trying to build a QNX os on qemu recently, I tried Asif's method, as shown below:

qemu-system-aarch64 -M xlnx-zcu102 -m 8G -serial mon:stdio -device loader,file=/root/xlinxbsp/images/QNX-IFS,cpu-num=0 -nographic -global xlnx,zynqmp-boot.cpu-num=0 -global `xlnx,zynqmp-boot.use-pmufw=true

The QNX-IFS file is the xlnx-zcu102 BSP package I downloaded from the QNX software center.When I run the above command, nothing is displayed, and the command cannot be terminated, only the kill command can be used to end the process.

I'm guessing that there may be a problem with my QNX-IFS file, but I'm not sure what the specific problem is? So I would like to ask how to solve this problem, and how did you get the QNX-IFS file?

Hi Shizhuang.li
you have to add the QNX-IFS startaddress:
qemu-system-aarch64 -M xlnx-zcu102 -m 8G -serial mon:stdio -device loader,file=/root/xlinxbsp/images/QNX-IFS,addr=0x00100000,cpu-num=0 -nographic -global xlnx,zynqmp-boot.cpu-num=0 -global `xlnx,zynqmp-boot.use-pmufw=true

This works for me.

Hi, I found this post helpful for creating the QNX VM, as I am struggling to create VM for QNX using Qemu.
after creating the VM using this way, I found that the VM do not have complete directory structure like /mnt/app folder and some other folder also missing.
while I also tried -device loader,file=rootfs.cpio.gz.u-boot,addr=0x04000000,force-raw=on but the result is same.
I wanted to know that am I missing some setting?

Second, what is the difference between M arm-generic-fdt and xlnx-zcu102 machine type in Qemu?

@tsi-345 could you please have a look

Thanks :)

Hi @FaiqueAli,

Find the start address in the .build file and pass it in the command.
I used below command and able to boot the os
qemu-system-aarch64 -M xlnx-zcu102 -m 8G -serial mon:stdio -device loader,file=QNX-IFS,addr=0x100000,cpu-num=0 -nographic -global xlnx,zynqmp-boot.cpu-num=1 -global xlnx,zynqmp-boot.use-pmufw=true

Thank for the rep
for which build file are you talking about?
I only have QNX-IFS file at hand..

@FaiqueAli
you should specify the start addr like this
qemu-system-aarch64 -M xlnx-zcu102 -m 8G -serial mon:stdio -device loader,file=QNX-IFS,addr=0x100000,cpu-num=0 -nographic -global xlnx,zynqmp-boot.cpu-num=0

the build file is the part of the BSP you will have to download from qnx software center (BSP for zcu102)
Try the mentioned address.

Thanks!

@charantejaabbavathini thank you for more information.
I am able to create the VM and mounted the diskimage, but now I can not execute mkdir inorder to create directory structure.
any idea about that ?
