RS232 Cape Rev B for BBB

Hi there,

Has someone used the new RS232 cape REV B before? Do you have
references on how to use it?

I need to use it to control a gsm board through AT commands and I have
no clue where to start.

Is it possible to use the older version of RS232 cape documentation as
a reference?

My basic guess and feelings are that:
I need to load a device tree overlay in order to set the pinmux, load
device drivers and the like. After that I will be able to communicate
with the other device throughout /dev/ttyAS0 and so on. Is that

Thank you!

Hi I have the same problem.


What jumper position are you currently using?



Maybe this will help you get started with your new RS232 Cape
