RK3399 Environment Configuration (Part 2): Samba Service Configuration and Cross-Compiler Setup

Samba Service Configuration

Introduction to Samba

Samba is a file and print sharing service based on the SMB/CIFS protocol, commonly used for sharing files between Linux and Windows. In our development environment, Samba can be used to:

Share directories from the Ubuntu virtual machine;
Directly access, copy, and modify files generated by the cross-compiler on the Windows host;

The sambashare folder here is my shared folder

Installing Samba

Execute the following on the Ubuntu virtual machine:

sudo apt update
sudo apt install samba

Configuring the Shared Directory

Edit the Samba configuration file:
```
sudo vi /etc/samba/smb.conf
```

Add the following content at the end of the file:

[sambashare]
path = /home/user name/sambashare/
readonly = no
browseable = yes

Replace user name with your actual username

Adding a Samba User

The Samba user must match a Linux user, for example, we use robin:

sudo smbpasswd -a robin

After entering the password twice, this user can log in to Samba.

Starting and Verifying the Service

Restart the Samba service:
```
sudo service smbd restart
```

Check the service status:

sudo systemctl status smbd

Access the shared directory from the Windows host: Enter the following in the Explorer address bar:

\\VirtualMachineIP\sambashare\

After entering the username robin and the corresponding password, you can access the shared directory.

Cross-Compiler Toolchain Installation

(This content is similar to the previous one, I will briefly reorganize it)

Downloading the aarch64-linux-gnu Compiler

Go to the Linaro toolchain page: 👉 https://releases.linaro.org/components/toolchain/binaries/

Select the aarch64-linux-gnu version, for example: Download link for version 7.3-2018.05

Download gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz.

Installing the Compiler

Create the installation directory:

```
sudo mkdir /opt
sudo chmod 777 /opt -R
```

Copy and extract the toolchain to /opt:

sudo cp ~/Downloads/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz /opt
cd /opt
tar -xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz

Configure environment variables (edit ~/.bashrc):

export PATH=/opt/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin:$PATH

After saving, execute:

source ~/.bashrc

Verification:

aarch64-linux-gnu-gcc -v

If the version information is displayed, the configuration is successful.
