unable to find overlay

Product support
#1

I’m building the balena os to include my custom layer. I’m building and placing the dtbo in /boot/overlays/ and then writing the path in uEnv.txt_internal hower on boot I get an error that the overlay is not found. When I ssh into the device the overlays are present so I’m guessing the reference in the uEnv.txt_internal is wrong. What is the correct syntax to use?

The uEnv.txt_internal should look something like:

enable_uboot_overlays=1
uboot_overlay_addr0=/boot/overlays/your_dtbo.dtbo

From the logs you pasted I can see BB-CAN0-00A0 can’t be found either, but eMMC1-01-00A0 and WL1835 are found and loaded, so check on your board if the overlays you added are present on the board in /boot/overlays/your_custom.dtbo, also in /mnt/sysroot/active/current/boot/

#6

Yes, this is my uEnv.txt_internal

enable_uboot_overlays=1

uboot_overlay_addr0=/boot/overlays/customoverlay.dtbo
uboot_overlay_addr1=/boot/overlays/BB-CAN0-00A0.dtbo
uboot_overlay_addr2=/boot/overlays/BB-CAN1-00A0.dtbo

disable_uboot_overlay_video=1
disable_uboot_overlay_audio=1

###Cape Universal Enable
enable_uboot_cape_universal=1

and from ssh I can see that all 3 overlays are present in /boot/overlays/ also in /mnt/sysroot/active/current/boot/overlays (symbolic link)

#8

Are you able to stop in u-boot cmdline and check with

ls mmc 1:2 boot/
ls mmc 1:2 boot/overlays/

if the overlays you need are there, or at least which ones are present? I recall checking CAN overlays on 2.56.0 and 2.58 and they were loading properly, wonder if your additional yocto layer could have anything to do with this.

#10

I tried a 2.58.3+rev1 build from the dashboard, with your configuration but without the custom overlay:

enable_uboot_overlays=1

uboot_overlay_addr0=/boot/overlays/BB-CAN0-00A0.dtbo
uboot_overlay_addr1=/boot/overlays/BB-CAN1-00A0.dtbo

disable_uboot_overlay_video=1
disable_uboot_overlay_audio=1
enable_uboot_cape_universal=1

And these overlays are found and loaded:

uboot_overlays: Switching too: dtb=am335x-boneblack-uboot.dtb ...

uboot_overlays: loading /boot/overlays/BB-ADC-00A0.dtbo ...
867 bytes read in 67 ms (11.7 KiB/s)

This makes me think there might be a problem with your rootfs, so checking what u-boot finds in that location should reveal if that’s a problem.

To stop in u-boot cmdline you need to set OS_DEV_UBOOT_DELAY=1 in your local.conf or layer.conf before building the image. It is used here.

overlays seem to be present. … :confused:

I assume the dtb was added in your build and was not copied manually. If so, you can share a github with your repository and we can try do a custom build like you do. Also specify what yocto machine you are using.

#15

yes the dtb and uEnv.txt_internal where added during the build.
You can see the code here: https://github.com/fencer/balena-beaglebone (i’ve also included the bblayers.conf and local.conf).
I’m building for beaglebone-green-wifi

#17

Ok, we’ll try build that repo and let you know.

#19

Hi,

I suspect you started a build with aufs and then switched the storage to overlay2 for the beagle green wifi, and the resulting build got corrupt. I commented out the balena_storage you switched in your local.conf and did a build from scratch, and can see your overlays get loaded:

I switched to overlay2 because it isn’t supported on the latest docker. I will try to downgrade.

#23

Looks like that did the trick! Still need to do some further testing but at least I do not get the error that it cannot find the overlay :smiley:
