Hi, I am running Ubuntu 18.04 inside a VM using VirtualBox hosted on Windows 10. I am trying to use a PL2303HXA serial to USB cable to get the serial output to my terminal in Ubuntu. I am doing this to view U-Boot.
Whenever the serial to USB is connected, the board doesn't boot up. When the serial to USB cable is connected and I run picocom -b 115200 /dev/ttyUSB0 the terminal waits for data on the port. As soon as I try to power up the board with the micro-USB cable, I get a fatal error and the serial port connection gets lost. picocom v2.2 port is : /dev/ttyUSB0 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 stopbits are : 1 escape is : C-a local echo is : no noinit is : no noreset is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv -E imap is : omap is : emap is : crcrlf,delbs, Type [C-a] [C-h] to see available commands Terminal ready FATAL: term closed The board boots up only when the serial to USB cable is disconnected from the PC. I tried to connect the serial to USB after powering up the board and that powers off the board. I am not sure why but the two connections (serial to USB and micro-USB power cable) seem to be mutually exclusive. I would appreciate any suggestions on how to resolve this issue.
