These signals are also the boot pins. You need to check the schematic of
the SOM to see what resistor values they are using to terminate the
signals. I would buffer the signals before connecting them to a LCD panel.

33 ohms is a good starting point. Once you have your board operating, use a
high speed digital oscilloscope to measure the waveforms on the LCD lines. If
they are square with no or little ringing, then the value is fine. If you see
ringing, start by increase the resistor value and if it gets wor
Depends on the LCD, distance, capacitance, and the connector impedance of
the SOM. The SOM supplier should be able to answer that question via an
application note.

Hello,
I am working with a System-on-Module based on the BeagleBone Black and I
need to connect a TFT LCD screen that goes in the front panel of a
rackmounted 19'' enclosure. The cable has to run a distance of about 15cm
and I am concerned about EMI stuff.
My question is: what is the appropiat
