Enable UART1 in Jessie BBB.

I’m using https://rcn-ee.com/rootfs/bb.org/testing/2015-07-19/console/BBB-eMMC-flasher-debian-8.1-console-armhf-2015-07-19-2gb.img.xz.

I want to use ttyO1.

I added that in uEnv.txt but it did not work.

cape_enable=bone_capemgr.enable_partno=BB-UART1

please help me, out.

sudo apt-get update ; sudo apt-get install git-core

git clone https://github.com/beagleboard/bb.org-overlays
cd ./bb.org-overlays

./dtc-overlay.sh
./install.sh

sudo reboot

Regards,

Thank you, Robert Nelson

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/

Robert,
Please disregard the last post. All I had to do was stty! It works!!! It works!!! So, I owe you a few drinks and/or dinner. How do I pay up?

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* .
