Virtual Embedded Linux Board Course. Virtual Embedded Linux Board Training Course Build your own virtual board using QEMU that has a complete boot flow from U-Boot to RootFS. This comprehensive course takes you step by step through engaging video tutorials and teaches you all the essential concepts and topics you need to develop your virtual board. What will you learn in this course?
- Introducing QEMU
- Use crosstool-ng to create your own toolchain
- Check your toolchain by writing a simple “Hello World” program
- Build the latest version of U-Boot
- Running the latest version of U-Boot in QEMU
- Setting up an SD card to store the U-Boot environment
- Build the latest version of the Linux kernel
- Running the latest version of the Linux kernel in QEMU
- Generate a simple initramfs and use it in QEMU
- Build the latest version of Busybox
- Generate initramfs from the busybox image and load it into QEMU
- Boot Rootfs from a virtual SD card
- Create a virtual SD card with three partitions and complete the MMC boot by updating the U-Boot environment
- Specifying the environment for running NFS Boot
- And…
