Cant get BB-UART2 starting on BB Grenn with bone-debian-4.1.12-ti-r29

Hello ,

I just downloaded bone-debian-8.2-test on my new BBGreen, I disable the emmc on the uEnv.txt and when I try to load manuallu the UART2
sudo sh -c “echo ‘BB-UART2’ > /sys/devices/platform/bone_capemgr/slots”

It end up with:

[ 1156.746283] bone_capemgr bone_capemgr: slot #6: BB-UART2 conflict P9.21 (#4:univ-all)
[ 1156.754681] bone_capemgr bone_capemgr: slot #6: Failed verification
sh: echo: I/O error

What is wrong ?


the cape-universal overlay: "univ-all" is already loaded.. To
disable this, open:


and remove:



Great !
Thanks Robert for this fast reply.

Should I suggest that you modify the comment on uEnv.txt == #In the event of edid real failures, or if installed on a BeagleBone Green, uncomment this next line

I am planning to install Mirko’s BBB-Mini Cape. According to BBB-overlay ; BB-BBBMINI-00A0.dts – dtbos: add ti,beaglebone-green it is already compatible ?
Will I be able to use the onboard BB-UART2 with this Cape installed (considering that the BBB-MINI is using USB4 & 5 only) ?

Best Regards
