Hi,  
I want to integrate mender on imx8qxpc0-mek board with Yocto.  
Is there a tutorial that describes the integration of mender on this platform.  
Thank you!

Hi Mahdi,  
you can take a look at [this page](https://hub.mender.io/c/board-integrations/6) for existing board integrations.

Hi Alan,  
Thank you for your reply,  
But I don’t see an integration process defined for the imx8qxpc0mek board in this page.

If there is not an already existing integration then you will need to do a custom one. [Docs are here](https://docs.mender.io/system-updates-yocto-project/board-integration).

Also, we do offer services to do custom integrations. More details [are here](https://mender.io/support-and-services/board-integration).

Hi Drew,  
Thank you for your reply,  
I was inspired by this patch to integrate mender for imx8qxpc0mek :  
[commit](https://github.com/mendersoftware/meta-mender-community/commit/71fdc24a71194fd69d50ed9ba48bda27d79e9a8d#diff-54562d56891478f08c1ab65d3c3545466d9f1affddfd841b5ffd4597e583136f)

I built the image for the imx8qxpc0mek knowing that I started from manifest imx-4.14.98-2.3.0.xml (sumo branch) with the addition of meta-mender and meta-mender-community.  
The build is OK.  
I got the 4 partitions after flashing the .sdimg on the sdcard.  
But the board does not boot and enters a loop!

Please, help me !

Here are the logs :

No idea, sorry.

As a first troubleshooting step I would recommend you take a look at the BOOTCMD environment variable and then run each of the steps individually to see if anything obviously wrong happens. That’s kind of a tedious activity, especially if you are using distro\_bootcmd, but it’s the only thing I can suggest.

This looks like the kernel may be built incorrectly but that’s just a guess.

Now, the board is booting.

OK, glad to hear you are making some progress. I suspect this issue is that the u-boot fw-utils installed inside Linux are not configured properly. The mender-client uses them to read and write the u-boot environment. From the Linux shell prompt, what does the following show?

`# fw_printenv | grep mender`

Hmm. That looks correct to me. What do the following show?

From your target board:

> lsblk  
> fdisk -l

and from your build machine

> bitbake -e core-image-minimal | grep ^MENDER\_

@kacf any ideas on this one?

> Failed to read the current active partition: No match between boot and root partitions

The u-boot environment seems to match up on the partition numbering and is read the same in both Linux and U-Boot.

Hi Drew,  
I think the problem is with mender\_setup which is not running.  
I updated the value of mender\_saveenv\_canary in u-boot

> setenv mender\_saveenv\_canary 1  
> saveenv  
> boot

After booting, I check the mender client, now the partition is seen by mender

I will test the switch between the partitions.

@drewmoseley

I wanted to switch between active / inactive partitions (mmcblk1p2 / mmcblk1p3)

root@imx8qxpc0mek:~#fw\_setenv mender\_boot\_part=3  
root@imx8qxpc0mek:~#fw\_setenv mender\_boot\_part\_hex=3  
root@imx8qxpc0mek:~#reboot

After reboot, I checked mender\_boot\_part an mender\_boot\_part\_hex values :

root@imx8qxpc0mek:~# fw\_printenv mender\_boot\_part  
mender\_boot\_part=3  
root@imx8qxpc0mek:~# fw\_printenv mender\_boot\_part\_hex  
mender\_boot\_part\_hex=3  
root@imx8qxpc0mek:~#

But the current partition is /dev/mmcblk1p2 as it was before the reboot

root@imx8qxpc0mek:~# journalctl -u mender -f

Not off the top of my head. You’ll need to break out to the u-boot command line and troubleshoot a bit. Print the BOOTCMD environment variable and manually step through it to see where it differs from the expected boot sequence.

Hi @drewmoseley ,  
Thank you very much for all your help and useful information !

The problem is with the mmcargs in uboot env.  
I updated the mmcargs  
=\> setenv mmcargs “setenv bootargs console=${console},${baudrate} earlycon root=${mender\_kernel\_root}”  
Now I can switch between partitions.  
\*I tested the inventory it’s Ok  
\*I tested the partial\_update it’s OK  
The current image is flashed in the sdcard.

Now I wanted to generate a build that I will flash it on the emmc.  
Here are the changes I made:

In the local.conf  
I changed :  
MENDER\_STORAGE\_DEVICE\_imx8qxpc0mek = “/dev/mmcblk0”  
MENDER\_UBOOT\_STORAGE\_DEVICE\_imx8qxpc0mek = “0”

In imx8qxp\_mek.h :  
I removed this line:  
#define CONFIG\_SYS\_MMC\_ENV\_DEV 1 /_USDHC2_/

I compiled u-boot, I generated a new image  
I flashed the image in the emmc with uuu.  
The problem is that the mender environment variables are not taken into account in u-boot.

Do you have any idea !  
Are the modifications I made for an image for the emmc are good or not?

Did you rebuild u-boot through Yocto? You will need to make your modification into a patch that is applied by the Yocto recipe to ensure that all the Mender patches are applied as well.
