I've a Raspberry Pi Model B. I want to connect its serial output to my PC and view the logs generated by it.
My serial to USB converter board uses FTDI FT232RL and supports both 3.3V and 5V (using a jumper on the board) and I use the 3.3V setting (as indicated by tutorials).
My problem is that I can't see any output on screen and none of the board's LEDs would blink (If I'd seen garbage output, at least I'd begin to change some settings like baud rate, but it's blank).
Here's what I do:
- Connect board to my computer
- Connect the Rx pin of RPi to the Tx of board, and Tx to Rx (I've also tested connecting Tx to Tx and Rx to Rx)
- Connect the ground pin of two devices together and power-on the RPi (The SD card contains Arch Linux)
A sample page to show me Rx and Tx on RPi : http://elinux.org/RPi_Low-level_peripherals
baud rate=115200 , stop bit=1, data bit=8 and parity and flow control set to None
On Windows I use Putty and on Mac I use 'screen' command or ZTerm app. On Mac I've tried to connect to both '/dev/cu.xxxxx and /dev/tty.xxxxx, where xxxxx is my board's name.
I thought maybe my board is not working; I connected it to my laptop (both Mac and Windows), connected its Rx and Tx pins together and typed on keyboard. Everything that I typed, was shown on screen (and Rx and Tx LEDs also blinked for each keystroke).
I've also tested the Arch Linux on SD and it's working without a problem.
Could you please advise me on how to troubleshoot this problem? Thanks in advance
I think I spotted my first problem: I installed Raspbian and now at least I can see some text, but it contains some garbage.
Any ideas on how to fix this? (I'm using the same config)
