Loading custom capes on Debian

[bremenpl]

Hello there,
I am suing bbb and a Debian Console image. I am strying to locate the place where the tree overlays are located but I cant. I tried greping for "BB-UART1" for example but I cant find it. Even though I can export it to slots. I have added my custom cape to /lib/firmware/ but when I try to export it to slots it cannot find the file. In the regular image all tree-overlays are stotred in /lib/firmware/ and in my image that folder is empty. I would really aprichiate any help, this is very urgent for me and I dont have much time :(

What kernel are you using?  (what is the output from "uname -a"
?)

I don't have much experience with device tree overlays so I might not be able to help, but what is the exact command you are using to echo it into the slot?

[Bremenpl]

root@beaglebone:/sys/devices/bone_capemgr.9# echo BB-BONELT_HDMIN1 > slots
-bash: echo: write error: No such file or directory

For some reason he doesnt see my .dtbo file in lib/firmware/ but or the other hand there are no other .dtbo files there. They are somewhere, because I can echo BB-UART1 for example, I just cant figue out where. I dont know where to put my .dtbo file or how to enable /lib/firmware/ directory for .dtbo files

I suspect it is a problem with your dtbo file.  I believe that some of the dtbo files that used to be installed in /lib/firmware have been essentially compiled in to the kernel in an attempt to fix some other issues.  My dtbo for my XBee cape is still in /lib/firmware and it works fine.  Doesn't automatically load off EEPROM at boot, but the running "echo XbeeFullCape0001>/sys/devices/bone_capemgr.9/slots" as root works.

btw:

`dmesg | tail` will give you more info one the error above..
