config-pin not working for eqep0, 2, 2b

[czyskows]

beaglebone black, 4.4.87-ti-xenomai-r121

python 2

After: echo cape-universala > /sys/devices/platform/bone_capemgr/slots

root@bela:# config-pin P8.11 qep

However,
root@bela:# config-pin P8.33 qep
root@bela:# config-pin P8.35 qep # for eqep1 are both fine

I've looked at the cape-uiniversala overlay here: https://github.com/cdsteinkuehler/beaglebone-universal-io/blob/master/cape-universala-00A0.dts
I should be able to do config-pin on the pins listed, but I just get the above errors.

Please paste the output of these commands:

sudo /opt/scripts/tools/version.sh

cat /boot/uEnv.txt

The Cape Manager has been deprecated by U-Boot Overlays. Since /sys/devices/platform/bone_capemgr/slots exists on your system, I believe it is not using U-Boot Overlays.

I would recommend trying this image:
Debian 9.3 "Stretch" iot

cape-universal and config-pin are now maintained in the bb-overlays repo.

The image that I'm using is for the Bela Board audio cape (bela.io). It's a real-time image for low-latency audio processing and necessary for the work I'm doing with the Beaglebone, so I can't use a regular distribution of Debian. Is there a way to work around? Thank you for the help!

@czyskows please paste the output of:

cat /etc/debian_version
cat /etc/dogtag

I suspect this quite an old image given that /opt/scripts/tools/version.sh does not exist.

@RobertCNelson @giuliomoro are you familiar with what current image people should use for Bela?

[giuliomoro]

This is our Bela image with Debian Stretch. We don't have the /opt/scripts in there, maybe we should? We are still on kernel 4.4.87, because we need to catch up with maintaining the Xenomai-patched kernel.
We are admittedly a bit confused by the death of capemgr and u-boot overlays, so we will follow up in the email thread with Robert about this very problem. Starting in March, we will have someone available to take care of all of this.

@giuliomoro here is some information that @RobertCNelson has added to the eLinux wiki:
https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays

[RobertCNelson]

Yeah, we've been talking with Bela, i need bring back the v4.4.x/v4.9.x xenomai options.. ;)

[pdp7]

@RobertCNelson any advice for @czyskows who wants to use both the Bela image and the eQEP peripheral?

root@bela:~# cat /etc/debian_version

[RobertCNelson]

right now a custom overlay, or tweak the bela base dtb..

[RobertCNelson]

ps, where is bela's am335x-bela.dtb stored?

[giuliomoro]

ps, where is bela's am335x-bela.dtb stored?

/mnt/boot/

same as uEnv.txt

[RobertCNelson]

Sorry, i meant in github/etc? then i can steal it and migrate it to an overlay. ;)
