I am trying to read my encoder (below) using my BBB
Encoder part #: (https://www.dfrobot.com/wiki/index.php/12V_DC_Motor_251rpm_w/Encoder_(SKU:_FIT0186))
Connections: Green to ground (P8.2), Blue to VDD5V (P9.5), Yellow to P8.12, and White to P8.11.
The diagram for these colors are at the above link
I have the dtbo files in the right location:
root@arm:/lib/firmware# ls -ltr bone*
-rw-r--r-- 1 root root 1082 Dec 7 01:09 bone_eqep0-00A0.dtbo
-rw-r--r-- 1 root root 1098 Dec 7 01:09 bone_eqep1-00A0.dtbo
-rw-r--r-- 1 root root 1098 Dec 7 01:09 bone_eqep2-00A0.dtbo
-rw-r--r-- 1 root root 1096 Dec 7 18:27 bone_eqep2b-00A0.dtbo
There is no 'slots' file as can be seen below
root@arm:/lib/firmware# uname -r

How do I load the right overlays with Uboot enabled? (I need Uboot for running a motor through a cape) @pdp7 @teknoman117
I think the new bone_eqep2b.dts that was added has incorrect comments.
The author updated the P8 pin numbers, but not the GPIO numbers, therefore they are not correct. Thx! ( I would try to fix it, but I am new to Github and I dont know how)...

I would aprichiate any help.
After exactly 1020 position reads the position stops updating
