Enable UART1 in Jessie BBB.

[박연호]

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.

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

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

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/
