PocketBeagle 2 ethernet cape

General Discussion
1

Hello everyone,

I just started working with the beagle board system and have an PocketBeagle 2. My problem is with the cape setup, my company made an custom cape that has an ethernet port that works with the PocketBeagle 1, and its my job to find out if this also works for version 2.

I have the PB2 running and have an usb ethernet connection, but it does not detect any cape, nor can i install any cape related files. i searched online and found this command:

sudo apt update ; sudo apt install bb-cape-overlays

But this only geves the result:

$ sudo apt update && sudo apt upgrade -y

E: Unable to locate package bb-cape-overlays

There is almost no documentation on how capes work in the PB2 system. is there anyone that could help?

With kind regards,
Cas Bremer

It has to be rewritten, what Ethernet overlay did you use before?

Regards,

3

Dear Robert,

Thanks for the fast reply,

From what i can tell this:

is the one we used before.

the problem is that i can not seem to get the bb-overlay download to work.

That repo had to go EOL, as device-tree’s turned out to not be a stable ABI… So we do kernel specific overlays.

In the case of the PocketBeagle2 (v6.12.x-Beagle: Files · v6.12.x-Beagle · BeagleBoard.org / BeagleBoard-DeviceTrees · GitLab ) , you’ll find all device-tree and overlays under:

/opt/source/dtb-6.12-Beagle/

Pull updates:

cd /opt/source/dtb-6.12-Beagle/
git pull

Install updates:

cd /opt/source/dtb-6.12-Beagle/
git pull
./build_n_install.sh

Dear Robert,

Thank you! at least that donwloaded!

Is there some sort of documentation? Does this method also have an uEnv.txt file? so yeah, where is it located.

With kind regards,

Cas Bremer

Step 1… need to port it first…

I’m looking at it, give me a little bit…

Regards,

Okay here are the full instructions: (fingers crossed it works with real hardware) tested only on a PB2 without the ethernet cape

Update repo, build and install:

voodoo@am6232-pb2-85:~$ cd /opt/source/dtb-6.12-Beagle/
voodoo@am6232-pb2-85:/opt/source/dtb-6.12-Beagle$ git pull
Already up to date.
voodoo@am6232-pb2-85:/opt/source/dtb-6.12-Beagle$ ./build_n_install.sh

Edit /boot/firmware/extlinux/extlinux.conf and add the new overlay to be loaded

fdtoverlays /overlays/k3-am62-pocketbeagle2-spi2-eth-wiz-click.dtbo

Example:

menu title PocketBeagle 2 microSD (extlinux.conf) (swap enabled)

timeout 50

default microSD (default)

label microSD (failsafe)
    kernel /Image
    append console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02860000 root=/dev/mmcblk1p3 ro rootfstype=ext4 resume=/dev/mmcblk1p2 rootwait net.ifnames=0
    fdtdir /

label microSD (debug)
    kernel /Image
    append console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02860000 root=/dev/mmcblk1p3 ro rootfstype=ext4 resume=/dev/mmcblk1p2 rootwait net.ifnames=0
    fdtdir /
    #initrd /initrd.img

label microSD (default)
    kernel /Image
    append console=ttyS2,115200n8 root=/dev/mmcblk1p3 ro rootfstype=ext4 resume=/dev/mmcblk1p2 rootwait net.ifnames=0 quiet
    fdtdir /
    fdtoverlays /overlays/k3-am62-pocketbeagle2-spi2-eth-wiz-click.dtbo
    #initrd /initrd.img

label techlab
    kernel /Image
    append console=ttyS2,115200n8 root=/dev/mmcblk1p3 ro rootfstype=ext4 resume=/dev/mmcblk1p2 rootwait net.ifnames=0 quiet
    fdtdir /
    fdtoverlays /overlays/k3-am6232-pocketbeagle2-techlab-cape.dtbo
    #initrd /initrd.img

Don’t place anything before failsafe, on any file loading failure, u-boot will load the first entry…

Upon bootup you’ll now see it loaded over debug serial.

Thank you so mutch!

I will try this out tomorrow, and report back with my findings.

honestly your work is a live saver! i am so frustrated about the lack of documentation or mention of the pocket beagle 2 board.

regards,

Cas Bremer

9

i know docs.beagleboard.org is being updated… but we still need to put in the time with all the overlays and examples. it’ll look better in a few months when all the examples are out!

Regards,

10

for the apt failures, make sure to set the date/time on the PB2.

11

Okay i have some good and bad news:

First is that i can succesfully download the new overlay system! and the overlay is loaded.

The bad news is that the network shield is not recognized. My company made an custom pcb with al sorts of stuff, and i can look how the ethernet is connected.

one of the things that is diffrent on my board is that the INT pin is connected to P1.02 instead of P2.03, i am going to try and figure out how to change that.

i think i have to make my own custom overlay and than add that in somehow.

Regards,

Cas Bremer

12

i made an custom file with the changes, but now new i install and then reboot.
The system does not say that any overlay is loaded. For now i will restart with an fresh install to see if i can get it to load an overlay.

13

Okay,

I now have an fresh install of the PocketBeagle 2 Debian 12.10 2025-03-25 Minimal (v6.12.x-ti).
and have gone thru all the steps to get the overlay to work.

I edited the k3-am62-pocketbeagle2-spi2-eth-wiz-click.dtbo file to use pin 1.02 as int.

The edits i have done are:

AM62X_IOPAD(0x015C, PIN_INPUT, 7) to AM62X_IOPAD(0x0164, PIN_INPUT, 7)

and

interrupts = <85 IRQ_TYPE_EDGE_FALLING>; to interrupts = <87 IRQ_TYPE_EDGE_FALLING>;

};

&main_pmx0 {
        w5500_pins: pinmux_w5500_pins {
                pinctrl-single,pins = <

                >;
        };
};


&main_spi2 {
        status = "okay";
        pinctrl-names = "default";
        pinctrl-0 = <&pb_spi2_pins>;

        #address-cells = <1>;
        #size-cells = <0>;

        w5500: ethernet@0 {
                compatible = "wiznet,w5500";
                pinctrl-names = "default";
                pinctrl-0 = <&w5500_pins>;
                reg = <0x0>;
                interrupt-parent = <&main_gpio0>;
                interrupts = <87 IRQ_TYPE_EDGE_FALLING>;
                spi-max-frequency = <24000000>;
                local-mac-address = [ 00 00 00 00 00 00 ];
        };
};

But the board does not detect it.

this is my beagle-version output:

that would be awsome!

I verified that the board does work with the PocketBeagle 1. so it has to be software related, what could be is that my hardware assignment is wrong, but at this moment i lack the knowledge to see understand what.

i have the same error so we are on the same page.

It seems to me that the spidev is not loaded in,
