i.MX 8MM mender integration error

[danie]

Hi,

I’m integrating mender with Yocto zeus for i.MX 8mm EVK. The build completed sucessfully without any errors but when I try to boot the device I get the following error.

Hit any key to stop autoboot:  0 
Run CMD11 1.8V switch
switch to partitions #0, OK
mmc1 is current device
Run CMD11 1.8V switch
** Unrecognized filesystem type **
## Error: "mender_setup" not defined
** Bad device specification 0x40480000 boot/Image **
## Error: "mender_try_to_recover" not defined
Booting from net ...

I follow the meta-mender-community integration for i.MX 8mm and modded it to support zeus. Full u-boot environmental variables are attached below for your reference.

Hi danie,

I’m currently working on MENDER zeus with IMX8M MINI EVK,
I already asked this question, and there is a wip branch holding support for IMX8M MINI on zeus,
Please check my post for details :

Is there a support for meta-mender-imx on zeus?

Hello All, I’m working on a custom board based on IMX8M Mini, before NXP released the zeus branch, I was working on sumo branch and using meta-mender-core and meta-mender-imx for IMX8 support, and all of that based on Uboot2018. But now, I’m trying to work on zeus branch, but I cannot find support for meta-mender-imx in meta-mender-community zeus branch. Is it gonna be supported ? Thanks, Talel

Best Regards, Talel

Hi @danie does running the following help?

u-boot=> env default -a -f
u-boot=> saveenv
u-boot=> reset

I have a port to that platform in my fork here: https://github.com/drewmoseley/meta-mender-community/tree/wip-zeus-imx-next
It’s untested since I don’t have the hardware but it is virtually identical to the imx8mnevk which I do have.

That port uses UEFI-GRUB as it’s bootloader integration point rather than U-Boot. If you want to give it a try please let me know how it goes.

Hi,

Thanks for the message, I’m not comfortable in using GRUB bootloader as I’m interested in HAB (High Assurance Boot) from NXP.

I tried your commands in u-boot console, yet no change. Same error is occuring:

In that case you will need to do a custom integration that uses U-Boot rather than Grub.

You don’t have all of the Mender boot code integrated into your U-Boot environment.
