In the box provided with the development board, there is a relatively large instruction manual, which should be the steps for Get Start.

The Germans are very rigorous in their work, which can be seen in the trial of the development board. According to the steps in the manual, verify step by step

1. Virtual machine construction

First, download the file in the USB flash drive that comes with the board and unzip it to the computer. Since it is a virtual machine disk file, it takes up a lot of space, 32.6G

Since there is no virtual machine installed on the computer, I need to download it, so I choose VirtualBox to download and install it.

When creating a virtual machine, select Linux-Ubuntu 64-bit and choose to create it with an existing disk file.

Select the file SO-558v1.vmdk extracted from the USB drive

Running a virtual machine, which is modified on the Ubuntu operating system. The instructions provide the username phyvm and password, but I don't seem to use them during operation.

Set relevant options in the virtual machine control system, such as network bridging, shared folders, etc.

After opening the virtual machine, I tried the network and was able to access the Internet normally.

2. Use the serial port to connect to the virtual machine

According to the instructions in the manual, use a USB cable to connect the development board to the X1 port, then check the port in the PC host. After seeing the port, switch the USB port to the virtual machine in the virtual machine control system.

Now open Microcom_ttyusb0 on the virtual machine desktop and log in as user root without a password

You can see the files in the development board system. You cannot use / here. Ctrl-/ will shrink the screen. I haven't found out how to output / yet.

So it doesn't feel very easy to use, but at least it can connect to the development board, modify files and run files, and the speed is also good. The manual gives the baud rate as 115200, but it was not used during the connection, so it should be the default setting.

3. Connect the main PC with an Ethernet cable

After setting the IP address of the wired network port to 192.168.3.10/24 on the host computer, connect the development board and the host, and you can see the information that the network cable is automatically connected.

Use the ifconfig command to view the address and test the ping host

It should be noted that the network port in the development board is X8, the network port with the barcode, and the one close to the HDMI interface.

At this point, you can connect to the development board via SSH in the host PC. I use putty here.

After connecting, enter the username root, no password is required

Use the ls command to list the folders under the root directory. There is no restriction on character input in putty, unlike in the virtual machine, where the "." on the numeric keypad will become ",".

The manual also provides a connection using SSH For Target. You need to change the network address of the virtual machine to 192.168.3.10/24 and set 192.168.3.10 as the gateway.

4. Development documents and directories

The 32.6G virtual machine should contain a lot of development board related resources. Due to time and ability limitations, only a phytec_tools folder is found on the desktop.

Other software mentioned in the manual, such as Toolchain, Eclipse, QT Creator, etc., are all in the /opt directory

These files should be used in the subsequent evaluation. Since I am not familiar with development under Linux, I am quite worried.

In addition, the manual provides the download compressed package address of this virtual machine
