Apalis Evaluation Board: FTDI TX Not working

Hi team,

A customer is trying to use Apalis Evaluation Board with Apalis IMx6 through FTDI (x29) but nothing is sent from the console terminal. I can open the console and read what is sent from the board but my commands are not being sent and LED 13 doesn’t light up. Jumpers 12 and 10 are set to USB.

I have tried it myself and I have the same issue. Is there something wrong with the FTDI?

If I change to RS232 with X28 (and JP10 and JP12) it works perfectly.

Thanks in advance for the help.

For now I have only 3 ideas:

  • Flow control settings of your terminal program
  • Issue with FTDI driver
  • TDI chip malfunctioning.

Hi Alex,

thank you for your answer.

We successfully solved the issue by reconfiguring the terminal program as you said, but we are not sure exactly which part was the actual cause as we can’t get it back to a non-working state.

We used the following command:
stty -F /dev/ttyUSB0 cs8 -parenb -crtscts

Thank you!
