Unable to boot properly with edi-cl built image on Compulab IOT-GATE-imx8

Hi,
I am integrating mender on Compulab IOT-GATE-iMX8 device for OTA firnware upgrade. I followed all instructions as mentioned in https://github.com/lueschem/edi-cl and am able to copy the mender-enabled image to USB stick and boot from the USB stick but with following error:
imx-sdma 30bd0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2

Also, am unable to set up WiFi with this new image. Trying to figure out the reason, I saw that wlan0 setup is removed from the edi project in one of the commits. I have below questions related to this:

  1. Why was the wlan- setup removed? I do not see this information in any high-level document. May-be I missed seeing it.
  2. Are there any plans to enable this back?
  3. If I want to add it myself, would just reverting the commit (while resolving needed conflicts) suffice or do you think there will be something additional to be done?
  4. How can I get successful loading of imx/sdma/sdma-imx7d.bin? A quick look indicates that this file is present in /lib/firmware/imx folder in rootfs in by-default provided image from Compulab, but the same when built using edi-cl, this file and the imx folder within rootfs is missing. I did try copying this file and booting, but with no success.

Please see below the boot log for reference.

@lueschem is probably best to answer any questions related to EDI

Hi Minal

Thanks for trying out the edi-cl setup!

Here are the answers to the above questions:

1) WLAN Setup

The WLAN setup got inherited from the edi-pi project configuration. However, it was not very elegant and therefore I removed it. From my point of view the setup proposed by Compulab is more elegant. As NetworkManager is not preinstalled by edi-cl you need to install it first and then setup the network:

sudo apt update
sudo apt install network-manager
sudo ip link wlan0 up
sudo nmcli dev wifi con "SSID" password "PASSWORD" name "WLANNAME"

To add this setup to the initial image I suggest that you fork edi-cl and add a new role that does the WLAN setup (by installing NetworkManager and eventually providing a configuration). If it is generic enough, we can also merge it into the edi-cl setup.

2) Re-add WLAN Setup

So far edi-cl just provides a minimal setup that can then be tailored to the needs of a specific project. But of course we can add an additional configuration that e.g. does a WLAN setup. The WLAN setup would also be a good example for a Mender state script that does a backup and restore of an existing WLAN setup when doing a full Mender based upgrade.
Anyway, I would prefer to do the WLAN setup based on NetworkManager instead of the very basic implementation done within edi-pi.

3) Reverting Commits

As explained above, I would not recommend that approach. But of course it should be feasible too.

4) sdma-imx7d.bin Failure

I did not care too much about the sdma-imx7d.bin failure as it is already present in the Compulab provided image:

compulab@iot-gate-imx8:~$ uname -a
Linux iot-gate-imx8 5.4.24-iot-gate-imx8-2.0 #1 SMP PREEMPT Thu Sep 3 10:30:00 IDT 2020 aarch64 GNU/Linux
compulab@iot-gate-imx8:~$ dmesg | grep -i error
[    0.770417] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2
[    5.977059] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

I did not detect any misbehavior that would be caused by this missing firmware.

If you need further assistance with the WLAN setup just let me know.

Best regards
Matthias

What actually worries me more are all the iwlwifi messages in your log. I cannot reproduce this:

Hi Matthias,
Thanks for replying back.

WLAN Setup:
I will try setting up WLAN using network manager. Will let you know how that goes.

sdma-imx7d.bin Failure:
I dont see this error in the Compulab provided image, so am not sure whats different. The image I am referring to is the one thats present in eMMC by default.
Also, I see that this bin file is present in boot/firmware/imx folder in compulab image. I did a quick try of copying the bin to edi-cl built-and-booted image but probably there is somewhere something missing in edi-cl setup/environment to be able to pick this bin correctly. I am not quite sure of the implications of not having this bin loaded in our use-case and hence wanted to have a clean matching setup between compulab image and edi-cl image.

iwlwifi messages
Thats strange that you cannot see the error messages but I can. Could it be probably related to the compulab release version being different, if any, between mine and your setup?
Compulab suggested to ensure that the setup has following kernel patch


This CompuLab patch should fix the iwlwifi load firmware issue that prevents the device from getting loaded correctly.
Reading the kernel build instructions https://github.com/lueschem/edi-cl/blob/master/docs/kernel_build.md, looks like this patch is not picked up?
I am very new to the edi, lxd, ansible world. I couldnt find out how is kernel built within the edi framework. Can you please help me with steps to apply this patch?

In your dmesg log snapshot, I see you are logged in as root. Is there a way to be able to login as root with edi-cl built image? I could login as compulab user but not root.

Thanks,
Minal

Hi Matthias,
I installed network-manager (ensuring wireless-tools, wpasupplicant and nmcli are installed) but I actually dont see any wireless interface on my device. I believe thats because of the iwlwifi errors and I definitely need the kernel patch in? I havent yet been able to figure out how to get that patch in (with edi-cl).

So, I think you are on uboot 2.0 and I am on 2.1

Thanks,

Hi Minal

Many thanks for your additional informations - they are very helpful!

The newer kernel version of the factory device and the patch you have pointed out will hopefully help to get rid of the iwlwifi issue.

Here are some background informations for the kernel build:

  1. The edi/Debian approach is to build a Debian package for the kernel within the Debian release that is also present on the target system. This is why we have the LXD container: Within the LXD container we can install the same Debian release that is also present on the target system. The pre installed cross compiler can then be used to cross compile the kernel.
  2. The resulting Debian kernel package then usually gets uploaded to a Debian repository. If you do not have your own Debian repository yet then you can also directly copy the package to the target device and install it using dpkg -i linux-image*arm64.deb. edi-boot-shim will make sure that the U-Boot setup gets done correctly.

Within this blog post I gave some more insights.

So the next thing we probably have to do is to update the kernel build instructions so that we are based on the latest Compulab kernel. I am happy to help here and I will post an update as soon as I find time to dig into the setup. If you are already successful earlier then please let me know.

About the root login: Usually I disable the root account (no password in /etc/shadow) and I do not allow it via ssh. This is just a security best practice. If you want to enable the root account then you can set a password (sudo passwd root) and modify the sshd configuration accordingly.

Best regards
Matthias

Hi Minal

I just pushed an experimental branch (kernel_upgrade_iwlwifi). The new kernel can also be found on PackageCloud. However, now the firmware imx/sdma/sdma-imx7d.bin is really needed. I will add it soon. In the meantime you can also install it using sudo apt update && sudo apt install firmware-linux-nonfree/buster-backports.
Does this new kernel fix the iwlwifi issue?

Best regards
Matthias

Hi Matthias,
Thanks for all the detailed explanation. It now all makes sense to me.
I will try your experimental branch/deb packages soon.

Re wlan0 setup, I feel there is no harm in having the network manager installed by default (just lilke the default compulab image setup)? That will make things look similar. I think its fine to start the wlan0 interface as recommended by Compulab, but the missing info/piece is the network manager related installation. I feel either that should be spelled out loud in edi-cl documentation so that novice person like me does not miss or rather I would say does not remain under impression that the only difference between default compulab image and edi-cl built image is the board integration related stuff. I am not sure if there are such other differences, if any, between the 2 images as I havent played around more with either of the 2 images.

I am sure you would have thought through well about not having the network manager installed by default. May be its just that I am quite new to this and hence feel it should have been there by default ( as one main reason of going through the mender exercise and edi-cl is to perform firmware upgrade OTA and hence having wifi capability by default). May be I am half-minded and failing to understand something. Would be keen to hear on your thoughts.

I will test the experimental branch and let you know.

Regards,
Minal

Hi Minal

In the meantime I have added the sdma-imx7d.bin firmware and merged the changes to master.
Your idea about NetworkManager is good and therefore I have opened this ticket.
Compulab also mentioned the WiFi issue in their release notes.

Best regards
Matthias

Hi Matthias,
Thank you very much for the updates. I confirm that iwlwifi issue and sdma-imx7 issue gets resolved with the latest changes.

compulab@iot-gate-imx8:~$

Also, thanks a lot for accepting and creating a ticket related to NetworkManager. Would be keen to know when are you planning to resolve it.

Please note that iwlwifi issue is resolved but I still cannot see the wlan0 interface in the ifconfig list. I think thats something that will be taken care along with the NetworkManager ticket?

For your information, you might know this but I see that with default compulab image I can see 2 ethernet interfaces displayed (eth0 and eth1) but with edi-cl built image I can see only eth0. Probably thats just one difference to get closer to the default image?

Also, a small feedback about some minor things when I went through the exercise of following instructions provided here:

  1. Under pre-requisites step1 (Install lxd) for Debian , I had to perform following:
    sudo apt install snapd
    systemctl start snapd.service
    sudo snap install core
    sudo snap install lxd
    sudo usermode -a -G lxd $USER

  2. While creating an image succesive time onwards (with and without recursive clean), I hit an error related to losetup. It tries to mount the files on /dev/loop6 and 7 but previous ones are already mounted and I have to manually detach them before triggering the command again.

Hope this feedback helps.

Thanks,
Minal

Hi Minal

Many thanks for confirming that the iwlwifi problem got fixed!

About the network interfaces:
I indeed just configured eth0. But the other interfaces should be available too. You can see them if you do an ifconfig -a.

About the NetworkManager ticket:
I do not know yet when it will make it to the top of my TODO list. Unfortunately I have more projects than spare time.

About the LXD installation:
Many thanks for pointing out this issue. I fixed the documentation.

About the loop devices:
What kind of error message did you get? I will try if I can reproduce this issue.

Best regards
Matthias

Hi Matthias,
Sorry, it didnt strike me that the interface was not up. I can see wlan0 and eth1 using ifconfig -a

About the loop devices, I will send you snapshots of what I mean, in my free time.

Would greatly appreciate if you can provide quick suggestion on how to add the installation of NetworkManager or in general any other packages(of choice). Apart from network issue, I am also looking at resolving the ticket as reference to do similar to install some other packages for our use case.

Thanks,
Minal

Hi Matthias,
I think my questions would be self-answered by going through the edi documentation. You can ignore my request on quick suggestion about how to install any other packages in general. I think I will figure it out myself.
Thanks,
Minal

Hi Minal

A new NetworkManager based setup is now available on this branch: https://github.com/lueschem/edi-cl/tree/mender_upgrade_and_networking
As soon as I have done a bit more testing I will merge it to master.

Best regards
Matthias

Hi Matthias,
Many thanks for the quick update. I will have a look at the branch shortly.

Regards,
Minal

Hi Matthias,
I confirm that I could get the WiFi up with this branch. I have not done detailed testing but the basic test in terms of ability to bring up wifi works nicely.
So, my overall initial issue of the sdma and wifi gets resolved. Thanks a lot for your support and for the quick changes.

Thanks,
Minal
