4DCAPE-43CT-CLB not booting properly with BBB

Lesept · December 7, 2022, 2:12pm

Hi
I’m just trying for the first time my brand new GEN4-4DCAPE-43CT-CLB display, bought at Farnell’s. I plugged the cape on my Beaglebone Black and power it on.
The display is alive, the board as well. There is a blinking underscore ‘_’ on the display, which stops blinking after a few minutes. But nothing else happens.

The first time, I also got an arrow on the screen, then the user leds of the BBB stopped blinking and 3 of them remained lit. But nothing else.
So I pushed the boot button on the board, the display showed the blinking _ which stopped blinking and the board freezed again with only one user led lit.

The board boots from the SD card, using the latest Debian 11 linux.

cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian

I have seen this thread, which says:

Open: /boot/uEnv.txt
dtb=am335x-boneblack-4dcape-70t.dtb
reboot…

I guess that I should do:

dtb=am335x-boneblack-4dcape-43t.dtb

but there is no dtb file with an appropriate name:

debian@BeagleBone:~$ ls /boot/dtbs/5.10.140-ti-r52/* | grep 4d
debian@BeagleBone:~$

What’s going wrong, and how can I fix it?
Thanks for your help.

I did this and now it boots ok.

As long as u-boot is new enough, it should work…

We can check and verify with:

sudo beagle-version

Here is the answer:

What will it do?

It should help you get video working out of box.
