UART on Pidora

[mobileoverlord]

so Pidora uses systemd instead of inittab. Does anyone know how to free up the UART connection on the GPIO? I have modified the /boot/cmdline.txt to remove the commands associated with /dev/ttyAMA0 but when I connect the rx and tx pins together or to a device and try it in minicom, I cannot get responses. says offline.

I'm not sure what you are asking.

My experience with Pidora is that getty is *not* running (on ttyAMA0) by default, and you have to jump through some serious hoops to get it running.

So, it should be off-by-default. Does that not agree with your experience?

So I guess I have everything set up properly, it appears that systemd does not have an entry for getty.

I am trying to connect the rx pin to the tx pin to test if the serial port if working. Minicom says offline and I can seem to get it to go online

Code: Select all

minicom -b 115200 -o -D /dev/ttyAMA0
