Problem loading correct overlay to use the config-pin tool

I am a newbie when it comes to how the Device tree overlay really works, so sorry in advance.

I would like to use the config-pin tool to configure gpio’s on my BBB.

I am using the Debian Buster IOT image.

Trying to query pin P8.11
debian@beaglebone:~$ config-pin -q p8.11
ERROR: open() for /sys/devices/platform/ocp/ocp:P8_11_pinmux/state failed, No such file or directory

I am able to query pin P9.20
config-pin -q p9.20
Current mode for P9_20 is: default

So I guess this means that the correct overlay file is not loaded to support P8.11 etc ?

The /boot/uEnv.txt is unchanged (came with Buster IOT), and it does have
enable_uboot_overlays=1
and
enable_uboot_cape_universal=1
I am unsure which dts this setting loads ? cape-universal-00A0.dts ?

Are all overlay files placed in /boot/dtbs/4.19.94-ti-r42 ?
I can see that BB_ADC-00A0 is loaded, but where is it placed, since it is not in above path ?

I have tried updating the kernel to R73, no change.
Can anybody here guide me on this ?

Thank you.

Best regards
Brian

This looks fishy… something forced am335x-boneblack.dts please try:

sudo apt update ; sudo apt install bb-u-boot-am335x-evm
sudo /opt/u-boot/bb-u-boot-am335x-evm/install.sh

and reboot, then run that script again…

Regards,

Odd… can you please post your /boot/uEnv.txt

Do you have a usb-serial adapter that can be plugged into J1?

Regards,

Ah perfect, let’s see what u-boot is doing!

Regards,

I hope you mean a dump of the boot messages, else please tell me.
Looking at the boot data, I am wondering about
debug: [enable_uboot_cape_universal=1] …
debug: [uboot_base_dtb_univ=] .

Should uboot_base_dtb_univ be blank ?
What are you focusing on ? I am trying to learn this.

any chance do you have a “/boot/uboot.env” file??

Regards,

enable_uboot_cape_universal=1
I am unsure which dts this setting loads ? cape-universal-00A0.dts ?

it triggers a seriously convoluted set of logic that’s all done via
u-boot scripting. there’s also some ugly interaction between that option
and the cape_uboot variable and the function capeloadoverlay.

i’ve had the joy snort of having to debug these aspects a few times:

to figure out how that bit of magic works i’d suggest that you
run a “printenv” while in u-boot and save the output (you indicated you
have console access); the loooong sections of not-quite-normal-shell
programs can then be massaged and perused with an editor that does syntax
highlighting. (your other option to find out what is going on there is
USTL: u-boot sources, include/configs/ti_armv7_common.h. without the values of the
variables on your bbX that’ll be of limited usefulness.)

Are all overlay files placed in /boot/dtbs/4.19.94-ti-r42 ?
I can see that BB_ADC-00A0 is loaded, but where is it placed, since it is not i
n above path ?

find /lib /boot/ -iname adc.dt*

maybe helpful, possible not 100% applicable to your situation:
for us, one thing that has caused overlay loading mismatches/kabooms
on some bb board types was a dud/outdated uboot environment
(e.g. an old uboot_wireless variable setting caused attempts to load the WL1835
overlay on a bbe that has a totally different wireless chip).

i don’t recall what your duster-generation u-boot uses to park its environment
(note that “uboot environment” != uEnv.txt), so YMMV:
we did the moral equivalent of an “env erase”, followed by “env default -f -a”
and a “saveenv” on the uboot console to get back to a more reasonable state of
affairs.

(as you can see from robert nelson’s latest post in your thread, newer builds of
the uboot save their env within the ext4 filesystem at /boot/uboot.env;
see also fw_printenv from the u-boot-tools package.)

@az143 ,

Thank you.

Seth

P.S. Nothing is easy when someone has created something away from another person and does not have 100% undivided attention to pay. So w/ that idea, thank you for the ideas and facts.

As you probable have noticed, I am booting from the eMMC.
Found another thread that mentions uBoot not being able to write to a different device than the sd-card.

So tried booting from the sd-card, entering uBoot and resetting the environment.

=> env default -f -a
 Resetting to default environment
=> saveenv
Saving Environment to EXT4... File System is consistent
Unsupported feature metadata_csum found, not writing.

** Unable to write "/boot/uboot.env" from mmc0:1 **
Failed (1)

Not sure what to make of this ?

Everybody,

Finally discovered that the problem is somewhat hardware related.
My beaglebone is plugged into our own “interface board” utilizing some of the P8 and P9 header pins.
I have an i2c RTC (MCP79400) connected to P9.19 (I2C2 SCL) and P9.20 (I2C2 SDA), this somehow trigs
uboot not to load am335x-boneblack-uboot-univ.dtb although enable_uboot_cape_universal=1.
I now realize that these pins are used for cape eeproms, and this is probably why uboot gets confused ?
I disconnected the RTC, and now the correct overlay is loaded !

I did expect that uboot would detect that the device connected on I2C2 is not an eeprom, and does not match any of the cape configuration strings identifying a particular cape ?

Does anybody know if this uboot behavior can be disabled ? or do I need to move my RTC to I2C1 instead ?

Thank you everybody for helping me out :slightly_smiling_face:

Hi Az143,

Thanks for taking the time, and giving your inputs.

find /lib /boot/ -iname adc.dt*

/lib/firmware/BB-ADC-00A0.dtbo
/boot/dtbs/4.19.94-ti-r67/overlays/BB-ADC-00A0.dtbo
/boot/dtbs/4.19.94-ti-r67/overlays/BONE-ADC.dtbo

In my case I only find it under
/lib/firmware/BB-ADC-00A0.dtbo
and since it seem to be loaded ok, that must be fine.

I tried booting to the uBoot terminal, and executed

=> env default -f -a
Resetting to default environment
=> saveenv
Saving Environment to EXT4… Card did not respond to voltage select!

I do see a few changes in the printenv output:

This line was changed:
board_name=A335BNLT
to
board_name=am335x

These lines were removed:
board_rev=EIA0
board_serial=2046SBI10516
bootcount=7
eth1addr=2c:ab:33:6a:bb:60
ethact=cpsw
ethaddr=2c:ab:33:6a:bb:5e

ver=U-Boot 2019.04-g923f8b8 (Jan 02 2022 - 19:05:15 +0000)

So not a lot of changes …
Rebooting after this did not change anything, but I guess the change was not saved !

I have inserted the printenv out put below this line

Sorry No, I don’t have a /boot/uboot.env file.

As you probable have noticed, I am booting from the eMMC.
Found another thread that mentions uBoot not being able to write to a different
device than the sd-card.

afaik the 2019-x u-boot versions don’t have the smarts to handle the
environment in more than one location, ie. no fallback.
at work we’re working around this by compiling two u-boot binaries, one
for our flashbable images which looks for its env on the sd card, and
one that gets installed on flashing which then solely consults the emmc.

Saving Environment to EXT4… File System is consistent
Unsupported feature metadata_csum found, not writing.

** Unable to write “/boot/uboot.env” from mmc0:1 **

that’s a known stuffup in the defaults shipped on many beagle images: u-boot
dislikes ext4 if the the metadata_csum feature is on. /etc/mke2fs.conf should
loooong ago have been fixed to not enable that when making filesystems on/for
beagles (but the bug report for that is unactioned).

if you can access the filesystem in question without booting from it,
then

tune2fs -O ^64bit,^metadata_csum /dev/… and resize2fs -s /dev/…

fixes that one.
