Cape Manager - cannot see HDMI & eMMC (4.1.18-ti-rt kernel)

I just upgraded by kernel and dtc version. Here are their outputs:

`
frank@beaglebone:/media$ uname -r
4.1.18-ti-rt-r56
frank@beaglebone:/media$ dtc --version
Version: DTC 1.4.1-g1e75ebc9

`

Now when I check slots, HDMI & eMMC are not shown:

frank@beaglebone:/media$ cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universaln

What might be the problem? What should I do?

I just checked https://github.com/beagleboard/bb.org-overlays/blob/master/readme.md, and seems like HDMI & eMMC are disabled by default, is it true? How can I be sure that those pins are not being used by HDMI & eMMC?

Thanks!

‘Enabled’ by default… Read the readme again, for the correct dtb= option for HDMI and emmc disabled.

Regards,

Thank you so much for your reply Robert, sorry I misread it. Then I have another question, then what it is the reason that when I check $SLOTS, I cannot see HDMI & emmc? Here is the output again:

frank@beaglebone:~/chp13/overlay$ cat $SLOTS 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1

Also, I added:

`
cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G

`

to uEnv.txt, however I since I cannot see HDMI & eMMC under $SLOTS, then how can I be sure that I freed them successfully?

Thanks again!

Btw Robert, this is my uEnv.txt file:

Because they are not separate dtbo objects in v4.1.x

Regards,

Sorry for spamming but wanted to ask just to be sure: so there is no way to be sure that I could disable hdmi & eMMC successfully?

What do you mean "to be sure"...

"read" the readme.txt:

https://github.com/beagleboard/bb.org-overlays/blob/master/readme.md

section:

BBB compatibility issues:

set the dtb for what you want.. and they set what they set..
