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.

[RASP] VirtualBox Raspberry Pi debuging

This article is for the perspective that planning to debug Raspberry Pi connected to (Guest) Ubuntu Virtualbox with USBtoUART and Screen/terminal. There are two important issues that you may face: You cannot detect USB devices: You probably have a permission issue on your Virtual box. Add your user ID to group vboxusers with this command: sudo usermod -a -G vboxusers $USER , log off, log on and try again. http://askubuntu.com/questions/481693/virtualbox-usb-add-device-filter-does-not-work-under-14-04 You cannot listen the ttyUSB0: Your permission of (guest) account should be feasible to the ttyUSB0: sudo gedit /etc/group goto line... dialout:x:20: add your "username" dialout:x:20:username http://askubuntu.com/questions/40959/how-do-i-connect-to-tty-com-dev-ttyusb0 After that, then you can detect the plug-in usb on-the-fly or before open the virtual machine. Then, screen /dev/ttyUSB0 115200 (DON"T FORGET TO INSTALL VIRTUALBOX GUEST ADDITION PAC...
