As of QEMU 3.0 the vlan parameter has been removed, so I had to change the -net option to -netdev, which has a similar functionality to vlan, ie run the device in a separate network. Signed-off-by: Sergiu Weisz <[email protected]>

We are going to move all of the asciinema recordings to this directory, and img is not an appropriate name anymore. Signed-off-by: Octavian Purdila <[email protected]>
Arguably that location is more appropriately and more importantly it fixes the issue with references when the files are included. So we can now remove the superfluous links. Signed-off-by: Octavian Purdila <[email protected]>
Arguably _images is a better place to store the .cast files. It also
fixes the following build issues:
Exception occurred:
File "/usr/lib/python3.8/shutil.py", line 261, in copyfile
with open(src, 'rb') as fsrc, open(dst, 'wb') as fdst:
FileNotFoundError: [Errno 2] No such file or directory: Documentation/output/teaching/lectures/file.cast
The issue here is that asciicast "rendering" happens before html
rendering and because of that the output lectures directory is not yet
available.

In some configurations Qemu requires rootfs image to be a size of 2. Resize the yocto rootfs to 64MB for now to fix the following error when booting ARM rootfs: qemu-system-arm: Invalid SD card size: 40 MiB SD card size has to be a power of 2, e.g. 64 MiB. You can resize disk images with 'qemu-img resize <imagefile> <new-size>' (note that this will lose data if you make the image smaller than it currently is).

This is an introduction to the ARM world. Starting with a simple overview of SoCs, will jump into how to setup a development environment by installing a crosscompiling. Then will go into how to compile the linux kernel and boot it using qemu. Finally, we will have a look at how ARM uses Device tree files to describe the hardware. Keywords: SoCs, BSP, toolchain, crosscompiler, i.MX6UL. Signed-off-by: Daniel Baluta <[email protected]>
