I am buy MediaTek X20 board and sensor board.https://www.seeedstudio.com/MediaTek-X20-Development-Board-p-2702.htmlhttps://www.seeedstudio.com/96Boards-Sensors-p-2617.html
and connect sensor board with X20 boardand plug usb cable to USB port on sensor board. (sensor board translate UART to USB)
I Expect u-boot and linux booting log.But nothing printed on COM port.
How can I see booting message of X20 board.
The X20 differs from the most of the other 96Boards products both because the console the image uses by default is running on LS-UART0 (instead of LS-UART1). It also has very fast default baud rate of 921600.
Sensor Board translate UART1 to USB. (ignore UART0)so I connect X20's UART0 to Sensor Board's UART1.
