Launch the application Putty on your windows PC. Viewing the device manager you can find the COM number. Plug in the USB to TTL cable to you windows PC. Putty is also great serial tool that supports wide range baud rate. Now run minicom rock5 to use the config above and connects to the ROCK 5 serial console. usb 1-6.4.3: FTDI USB Serial Device converter now attached to ttyUSB0įirst add current user to plugdev group to use minicom without sudo or root.Įdit your ~/.bashrc and add the following line with some default parameterĪlias minicom='minicom -w -t xterm -l -R UTF-8'Ĭreate and edit file ~/.minirc.rock5, add the following content:

The default serial setting for ROCK 5 u-boot and kernel console is: If you know how to set custom baudrate on macOS, please add an item here to show your findings.Ĭonnect the USB to TTL serial cable as below. It seems that the serial tool on macOS platform can not support custom baudrate such as 1.5Mbps due to driver restriction.The instructions below use a CH340_series based cable. We also tested that some cable does not work well. Some model of CP210X and PL2303x have baudrate limitation,and the FT232RL have some power issue(20211112), please check the specified model. The default baudrate of ROCK 5 is 1500000(1.5Mbps), please check if your USB to TTL cable support 1.5Mbps baudrate.
