Openwrt serial console mini computer8/31/2023 Wiring between the Yocto-Serial and the OLinuXino Beware, you must connect the board UART_TXD2 line on the Yocto-Serial RX line, and vice-versa, otherwise communications won't work. To access this serial console, you must connect the Yocto-Serial to the board three pins: GND, UART_TXD2, and UART_RXD2. The only solution is to activate the network with the serial console. This is not easy because this board doesn't have a display output. To access the OpenWRT interface, you must therefore start by modifying the network configuration. Unfortunately, by default, the Wifi network is disabled and Ethernet ports are not routed. It's a small board using a mips CPU and it comes with a pre-installed OpenWRT distribution. But you can also use a Yocto-Serial.įor this post, we are using an RT5350F OLinuXino. The traditional solution is to use a USB-serial adapter sold by the constructor. The problem is that no computer has a serial port anymore and if you have an old enough computer to have an RS232 port, you can't use it because the RS232 port works in 12 Volts. In this case, the solution to configure these boards is to use a serial console. Some of these mini-PCs have an HDMI output, but other, such as the OLinuXino, don't have a video output. Many home automation projects use mini-PCs running under Linux.
