RNDIS Host to connect Adalm Pluto

huseyinkozan · October 13, 2023, 2:02pm

Hi,

I have a custom build image with below added. BSP is 5.7.0. We have configured Pluto to static IP to 192.168.7.1. After ifconfig usb0 192.168.7.20 command, I cannot ping or ssh the device.

Pluto works at RNDIS mode, but I also tried NCM and ECM. Couldn’t connect at all.

Where should I look for the make connection ?
Which eth mode do you prefer for the connection ?

At some *.cfg files that appended to config;

CONFIG_USB_NET_RNDIS_HOST=m
CONFIG_USB_NET_RNDIS_WLAN=m
CONFIG_USB_CONFIGFS_ECM=m

At linux-toradex_5.4%.bbappend file;

KERNEL_MODULE_AUTOLOAD += " \
    rndis_host \
    rndis_wlan \
    cdc-acm \
"

Hi @huseyinkozan ,

Sorry for the delay in responding.

Taking a quick look at your dmesg logs I don’t see any obvious errors here. Apparently the device is properly recognized. Do you have to manually load the relevant kernel modules with modprobe or are they loaded automatically when you plug the device, as they should?

According to this article (Ethernet/Network (Linux) | Toradex Developer Center) by default our BSP reference images use systemd-networkd to manage USB RNDIS. Maybe it is necessary to configure it to support your device?

I noticed you’re using BSP 5.7.0. Can you check if the same issue happens on our latest BSP 5 production release (5.7.2 as of now) and our latest quarterly BSP 6 (6.4.0 as of now)?

Best regards,
Lucas Akira

Hi @lucas_a.tx ,

Nope, thanks for the reply.

Below lines at the kernel bbappend file adds module files to /etc/modules-load.d/ dir. I may try to load at device plug tomorrow.

I tried RNDIS, but I should check the article that you give. Thanks.

I have checked both 5.7.0 and 5.7.2. But, not any 6 version BSP. The last time that I try 6 was not a success at LCD display. I may check if not find a solution from RNDIS configuration.

I have tried;

Remove modules from /etc/modules-load.d/ and loaded autmatically.

Added /lib/systemd/network/rndis.wired with below content;

[Match]
# We use type since device name depends on Kernel version
# udevadm info --query=property /sys/class/net/usb0
Type=gadget

[Network]
Address=192.168.7.2/24
DHCPServer=yes
[DHCPServer]
EmitDNS=no
EmitNTP=no
EmitRouter=no
EmitTimezone=no

Installed 6.4 refecence image.

6.4 image does not contains rndis_host, so I tried NCM mode.

Where should I look at the next step ?

Hi,

We tried 6.4 again. It creates eth1 and took IP, but usb0 not. I am attaching some info below.

Out current BSP is 5.7.x and it will take time to upgrade to 6.4. What can we do to work it at 5.7 ?

Hi @huseyinkozan ,

We tried 6.4 again. It creates eth1 and took IP, but usb0 not. I am attaching some info below.

So apparently on BSP 6.4 eth1 is created and you are able to get your device to work via NCM, is this correct?

I’ll try taking a closer look at your dmesg logs to see if I can find anything interesting. Maybe it’s a kernel module that needs to be included?

Best regards,
Lucas Akira

huseyinkozan · October 24, 2023, 11:26am

Yes, correct.

Only 8021q is missing at 5.7, but its directly included;

# CONFIG_VLAN_8021Q_MVRP is not set

After removed startup module loads from /etc/modules-load.d, I realize that below errors come. At my previous trials, I thouth errors was a cable/power issue, and discarded it. May be related.

Hi @huseyinkozan ,

From the dmesg logs you provided I can’t really see any messages pointing to a driver/module error. One difference I noticed between the dmesg logs from 5.7.0 and 6.4.0 is that on 5.7.0 it does not have the usbcore: registered new interface driver <module> messages.

After removed startup module loads from /etc/modules-load.d, I realize that below errors come. At my previous trials, I thouth errors was a cable/power issue, and discarded it. May be related.

It may be related, though from what your logs showed it looks like the device was properly recognized.

For BSP 5 we released two versions: one with the upstream kernel and another with the downstream kernel forked from NXP. Do you know which one you used for the tests?

You can check that by running the command below:

root@colibri-imx6-10706262:~# cat /etc/os-release
ID=tdx-xwayland-upstream
NAME="TDX Wayland with XWayland Upstream"
VERSION="5.7.2+build.21 (dunfell)"
VERSION_ID=5.7.2-build.21
PRETTY_NAME="TDX Wayland with XWayland Upstream 5.7.2+build.21 (dunfell)"
DISTRO_CODENAME="dunfell"

The downstream version output is:

root@colibri-imx6-10706262:~# cat /etc/os-release
ID=tdx-xwayland
NAME="TDX Wayland with XWayland"
VERSION="5.7.2+build.21 (dunfell)"
VERSION_ID=5.7.2-build.21
PRETTY_NAME="TDX Wayland with XWayland 5.7.2+build.21 (dunfell)"
DISTRO_CODENAME="dunfell"

Can you try testing the alternative version of BSP 5 i.e. downstream if you tested the upstream one and vice-versa?

Best regards,
Lucas Akira

huseyinkozan · October 26, 2023, 7:43am

Hi,

We are using downstream. This is the DISTRO line from local.conf

DISTRO ?= "tdx-xwayland"

I tried to change it to upstream like below;

DISTRO ?= "tdx-xwayland-upstream"

Kernel is not stable, usually gives kernel panic, and stacks at boot. But, I managed to get below information;

Hi @huseyinkozan ,

Kernel is not stable, usually gives kernel panic, and stacks at boot.

That’s very strange, especially considering that it’s the upstream kernel. Did you make any other changes in the Yocto build?

From your dmesg logs apparently all modules load as expected, and I didn’t see any error messages related to the Adalm Pluto, so I don’t think that the loaded modules are the problem here.

Given that on BSP 6 you got an eth1 entry on ifconfig in addition to usb0, I would expect that RNDIS should get you eth1 if it works as intended.

Maybe it’s worth trying to get NCM to work on BSP 5, given that it works on BSP 6.

Best regards,
Lucas Akira

Hi,

We adapted our cahnges to my build env at here; GitHub - huseyinkozan/toradex-docker-yocto-builder . You can build an image that we have.

Here, you can find some info from device; Upgrade BSP 6.4 by Vergilerindir · Pull Request #3 · huseyinkozan/toradex-docker-yocto-builder · GitHub .

After boot and plug the device, we need to give ifconfig eth1 up command to show the eth1 at the ifconfig output. How can we do this automatically ?

Can we compare and find the required changes ? We want to use downstream, if possible.

We are trying all modes that Pluto suports; RNDIS host, NCM and ECM.

Hi @huseyinkozan ,

After boot and plug the device, we need to give ifconfig eth1 up command to show the eth1 at the ifconfig output. How can we do this automatically ?

You can create a udev rule to run a user-defined script when plugging-in your USB device.

Can we compare and find the required changes ? We want to use downstream, if possible.

You can try comparing the driver differences between BSP 5 downstream and BSP 6 upstream e.g.:

BSP 5 downstream:
- rndis.c « function « gadget « usb « drivers - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules
- cdc-acm.c « class « usb « drivers - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules
BSP 6 upstream:
- rndis.c « function « gadget « usb « drivers - kernel/git/stable/linux.git - Linux kernel stable tree
- cdc-acm.c « class « usb « drivers - kernel/git/stable/linux.git - Linux kernel stable tree

Just to confirm: Which image are you building with BSP 5.7? From the Yocto Builder GitHub link you referenced there is a custom image named minimal-image inherited from the core-image class. If that’s the case you try building our BSP reference minimal image i.e.

bitbake -k tdx-reference-minimal-image

And see if the device works there?

Best regards,
Lucas Akira
