Serial port works in Windows, but it does not work in Linux

#1 Post by rtek »

Hi,

Using a logic analyzer and an FTDI FT232RL serial port, I was able to get this data, and apparently it should be the reason it works in Windows, but it does not work on Linux.

(Connections: TX, RTS, DTR).

Does anyone know how to solve this problem? Is it a driver problem?

Thank you.

(This signal is generated by using the Arduino IDE + STM32duino bootloader)

Please provide enough information and in more exact detail, so that anyone reading this can have even the minimum understanding of what you are doing.

Presumably you have two computers, describe them. Are you dual booting the machine or how are you changing the operating system? What OS is on the other end? Is the machine that is changing the operating system the one that you suspect has the trouble or is it the other end? I looked up "FT232RL" and it does not appear to be a serial port, but a USB to serial UART interface used in many devices in different ways, Are you using a USB TTL serial cable, like one end is USB and the other is just four wires (RX/TX,Vcc, ground)? What baud rate is that? It appears to be different in the two images. Your github issue link pulls a 404
