Robert,
I just bought a Circuit Co RS-232 cape. It is revision B1. Does this install work for that cape or do I need to do something different? I am using a very recent Debian installation. Everything works great except for this cape!

The jessie lxqt image's should work out of the box with that..
dmesg | grep bone
Regards,
Oh wait, B1 doesn't have eeprom, so we can't detect it...
Depending on what jumper you have it set for:
/boot/uEnv.txt:
cape_enable=bone_capemgr.enable_partno=BB-UART0
cape_enable=bone_capemgr.enable_partno=BB-UART1
cape_enable=bone_capemgr.enable_partno=BB-UART2
cape_enable=bone_capemgr.enable_partno=BB-UART4 #hdmi must be disabled
Regards,
WOW, it loaded. dmesg says so any way. The echo test > /dev/ttyO1…ttyS1 does not fail, but the output is not showing up in my terminal window. Using another BB and a debug cable does send data to UART0.
Do I need to apply this change? http://www.berriman.co.uk/beaglebone-black-with-rs232-cape/

Hi,
We are using TI SDK 03.02.00.05 with Kernel 4.4.32
I didnt get /dev/ttyO* when i enabled UARTs in am335x-bone-common.dtsi and am33xx.dtsi files but im getting /dev/ttyS*.
So how to get /dev/ttyO* .
And how to usse overlays on latest kernel OR withought Overlay how can i test UARTs on Beagle Bone Black.
Please suggest me any solutions, waiting for your reply…
