Alright, I am stuck on this problem.
I am trying to connect to the Raspberry Pie 4 via a USB to TTL Adapter. Specifically this one:
- USB 2.0A Public Interface
- Built-in FTDI FT232 Chip
- Supports 1.8V, 3.3V, 5V TTL Levels
I am using picocom to attempt to connect to the raspberry pi 4.
picocom -b 115200 /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AG0JNTJ3-if00-port0
picocom v3.1 port is : /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AG0JNTJ3-if00-port0 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 hangup is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv -E imap is : omap is : emap is : crcrlf,delbs, logfile is : none initstring : none exit_after is : not set exit is : no Type [C-a] [C-h] to see available commands Terminal ready
And it just hangs.
I have placed the default rpi4 erlinit.config into the overlay directory and changed the output to ttyS0 but it is not showing up in the final firmware build. What is displayed is tty1.
Any help is much appreciated.
