BeagleBone Series - Basic Parameters and Environment Configuration

BeagleBone Series - Basic Parameters and Environment Configuration Hardware Resources USB Type-A: used as a USB host mode USB Micro: used to power the board and as a slave LEDs D2: flashes as a heartbeat light during startup D3: lights up when reading/writing SD card data D4: lights up when the CPU is active D5: lights up when reading/writing eMMC Boot/User button: regardless of whether it is pressed or not, if there is an SD card, it will default to boot from the SD card (different paths lead to the same goal). After booting, it acts as a normal button, connected to GPIO_72. I2C Grove interface: connected to I2C2 Uart Grove interface: connected to UART2 Serial Debug: connected to UART0, with the pins near USB as pin1, and from pin1-pin6 as: GND, NC, NC, RX, TX, NC Environment Configuration Driver Installation Issues In Windows 10 and above, the default is to use driver program forced signature, which may be the reason for the driver installation failure. Solution: Hold down shift and click restart the computer Enter Troubleshoot - Advanced Options - Startup Settings, and click Restart After restarting, follow the page prompts and press 7 on the keyboard to disable driver program forced signature After booting, you can install the BeagleBone driver program normally Image Download and Burning Official image download address: https://beagleboard.org/latest-images Burning tool: https://sourceforge.net/projects/win32diskimager/files/latest/download Burn the image into the SD card, power off and insert it into the BeagleBone, and the system will boot from the SD card next time it is powered on. Using Command Line Tools for Access Using Serial Port Access Use a USB-to-serial connection to connect to the onboard serial port, and open a serial port tool (such as WindTerm) on the computer for connection. (The initial username and password are both root) The baud rate is 115200! Using Ethernet Access Use the command ifconfig in the serial connection to find the Ethernet address and connect through it. The username is debian and the password is temppwd. Access via USB usb0: 192.168.7.2 usb1: 192.168.6.2 Access using SSH, with the username debian and password temppwd. Enable root account with SSH shell vi /etc/ssh/sshd_config Change #PermitRootLogin prohibit-password to PermitRootLogin yes. Seeed OLED Driver (SSD1306, I2C, 12864) Use pip3 to download the smbus2 package: py sudo apt-get install python3-pip pip3 install smbus2 Refer to the program in Grove - OLED Display 0.96 inch.
