Kevin learns ZED 2: sharpening the knife without cutting the firewood

Among the seven habits of high-performance people, the last one is Sharpen the saw, which is generally translated as: constantly updated, after reading it, I don’t know what it is. In fact, the English original meaning is the person who saws wood, don’t just have to saw all day. Wood, sometimes it should stop, use a sickle to repair the serrations, and let the saw be sharply written. Obviously, it means that the knife is not mistakenly cut.

Continue to do the <embedded system software and hardware collaborative design combat guide - based on Xilinx ZYNQ> experiment 1.2.

This experiment mainly allows everyone to partition the SD card and copy the entire linux file system into it. Then run the full-featured linux.

This thing, the windows world, or quite a simple drop, nothing more than the SD card is divided into two disks, a disk installed BOOT.BIN, a file installed in the operating system. Sadly, windows does not support the ext file system, so Such a simple thing becomes troublesome.

If you must do it under Windows, there is also a way to use the ParTITIon Wizard software to create FAT and EXT4 partitions. Then, using Ext2fsd software under Windows, copy a bunch of directories and files from the linaro package on the CD to SD. In the card, I am finished. I have tossed this routine for a while, found that downloading software, installation, it is very troublesome. In the future, many experiments still have to continue running under linux, so still have to install linux.

Running Linux with a single machine is too cumbersome. I don't bother to switch back and forth between Linux and Windows. After all, the word is used. Therefore, I especially like to use Virtualbox virtual machine to run ubuntu linux under Windows. Free, this is Sun's credit. After the acquisition, I changed Oracle. This program has been used for several years, so that when the Mac Air computer can't use the China Merchants Professional Edition, it can also be used to run Windows on this virtual machine. .

Of course, every time I install it, I will repeatedly encounter some common problems. If I am not familiar with it, I will fix these small problems. If the experiment is not done, I will sweat. Considering that the rookies are against English, they are deeply hated for the command line. Installed the Chinese version of the drop ubuntu, and try not to use the command line in the book, use the graphical interface to get the experiment.

After installing ubuntu, partitioning on the security book, copying the file, and getting an SD card with boot linux, there is no big problem in doing it.

The so-called sharpening knife does not mistake the chopping power, often tossing some small tools, or is it full of useful drops.

Key points under Virtualbox:
1. When installing, the network card should choose the Bridged Adapter mode, so that the virtual machine can be connected through the host network. If you can't connect to the network, it will be very slow to install.

2. To configure an empty USB filter for the virtual machine, any USB device plugged in and virtual can be used. If it doesn't match, your SD reader will not be reflected.

3. Drag the entire linux file system directly from the package file on the CD to the ext4 partition of the SD card.
