[Gem5] Full system Simulation with Official Kernel

I follow the youtube provided by Gem5 to get the inspiration.
(http://gem5.org/Running_gem5#Full_System_.28FS.29_Mode)

I download the file here:
http://www.gem5.org/dist/current/arm/
with
http://www.gem5.org/dist/current/arm/aarch-system-20170616.tar.xz

Then Set up M5_PATH as the place I extract the files:
"/home/khchen/full_system_images/"

If the setting is correct, assigning the disk-image will finish the rest of setting for dtb and kernel specifications.

So far I can only use this img (aarch32-ubuntu-natty-headless.img) as my disk-image to run up to the login interface of the ubuntu:

build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/khchen/full_system_images/disks/aarch32-ubuntu-natty-headless.img

With the other imgs, for example like "aarch64-ubuntu-trusty-headless.img", I think the kernel and the dtb should be given manually, because it will automatically load something with aarch32 prefix which doesn't make sense:

info: kernel located at: /home/khchen/full_system_images/binaries/vmlinux.aarch32.ll_20131205.0-gem5


info: Loading DTB file: /home/khchen/full_system_images/binaries/vexpress.aarch32.ll_20131205.0-gem5.1cpu.dtb at address 0x88000000

RSB+RTEMS 5/6 with QEMU-SMP (ARM realview_pbx_a9_qemu as example)

Since I got a request regarding this blog  written in 2016, summarizing again the complete flow with the latest version of RTEMS could be a good idea. Prepare a suitable workspace according to the adopted operating system on your host ( https://docs.rtems.org/branches/master/user/hosts/index.html ):  sudo apt-get build-dep build-essential gcc-defaults g++ gdb git unzip pax bison flex texinfo unzip python3-dev libpython-dev libncurses5-dev zlib1g-dev Checkout RSB and build: git clone git://git.rtems.org/rtems-source-builder.git rsb change directory to rsb/rtems/ and type ../source-builder/sb-set-builder --prefix=<the path you like to store the built toolchains> <the name of bsp> For example, to use QEMU, I need toolchains for ARM, so: ../source-builder/sb-set-builder --prefix=/home/kh.chen/respository/build/. 6/rtems-arm This will take a while. Please ensure your connection is reliable. Add the built folder into your PATH. For example, you can add one line in ~/.bas...

[ubuntu] Removing the instance/package which is not fully installed from apt-get

When I'm installing g77-3.4 for pgplot, I trivially use dkpg to install it. However, g77-3.4-doc is not able to fully installed. And I stuck for this kind of error due to the broken packages (refer to here ): dpkg: error processing realplayer (--configure/--purge/--remove): (Whatever messages) Errors were encountered while processing: g77-3.4-doc cd /var/lib/dpkg/info sudo rm g77-3.4-doc* sudo dpkg --remove --force-remove-reinstreq g77-3.4-doc Hmm, now apt-get works well again. https://www.youtube.com/watch?v=S9HJ-iAzf3k
