Dear Community;
We are planning to move from TK1 to iMX8QM processor. With TK1 we use L4T. To make the transition as easy as possible we want to use Ubuntu rootfs. To get that this is what I have thought:
1.-Download Linux Console Image.
2.-Extract the image.tar.
3.-Replace rootfs with Ubuntu rootfs.
4.-Write the image to an SD/USB?
5.-Load Toradex Easy Installer to iMX8 and flash it? Flash from U-Boot?
I am not sure with steps 4 and 5. However, before that, I am stuck in step 3. I have downloaded TEZI image for iMX8 but there I don’t see any “rootfs” folder. I think it is because it is TEZI image. I can not find iMX8 image here.
Thanks in advance.
Ander.
3.-Replace rootfs with Ubuntu rootfs.
The tricky part will be any kind of hardware-accelerated graphics/multimedia requiring special downstream drivers. For any of this to work further integration would be needed. If you plan to do a headless system without any graphics/multimedia your approach may be sane. You may also find some more information here:
4.-Write the image to an SD/USB?
Nowadays, one would be using WIC images for this:
5.-Load Toradex Easy Installer to iMX8 and flash it?
Yes.
Flash from U-Boot?
This legacy way of installing images is no longer supported.
Hi @marcel.tx ;
Sorry for the late answer. I am trying to load Toradex Easy Installer for iMX8 but I can not. I am following this procedure:
1.-Remove X2 Jumper.
2.-Plug USB OTG.
3.-Connect the two pads of JP4.
4.-Power on Ixora.
5.-Unplug JP4 jumper.
6.-Run recovery-windows.bat
Then the installation process goes from 0 to 100 and gets froze there:
C:\Users\hp\Documents\apalis-imx8_toradexeasyinstaller_2.0b5-20200519\Apalis-iMX8_ToradexEasyInstaller_2.0b5-20200519>recovery-windows.bat
Downloading Toradex Easy Installer…

When the process reaches 100% Windows makes a noise similar when a USB is unplugged, but I can not connect through VNC or HDMI to the Easy Installer. I have tried with USB2 and USB3 ports with the same results. However, when I use USB3 I get this ilne:
3:3 1/ 1 [=================100%=================] SDPS: boot -f …/imx-boot
and this USB2:

Any kind of help is welcomed. Thanks in advance.

Hello Andermutu,
Well, I saw some Windows users having a problem with the recovery mode. And it is usually a Problem with windows.
Is there a way that you would try it under Linux?
Best Regards,

Most useful would be the serial console output of the board as a textual file. For this one would need a suitable adapter cable:
Looking at your output it loads the initial so-called boot-container and then stalls. This could, of course, have various causes but the most likely is that it somehow fails to initialise the USB fastboot mode which would be used to transfer the actual Toradex Easy Installer.
Hello @matthias.tx,
I have tried with a Virtual machine but does not work. Usually gets stuck at 30-70% of the process. However, I think it is because USB conflict between Mac OS and Ubuntu Virtual machine.
I will consider installing Ubuntu on another machine.
Thank you,
Ander.

Thank you,

Most likely this is what you are seeing and using a later nightly build of the Toradex Easy Installer should alleviate the problem:
Hi @marcel.tx,
Using the Nightly build I can easily load Toradex Easy Installer. However, I have not understood the process of installing Ubuntu on iMX8. We don’t need any hardware-accelerated graphics/multimedia for now. Regarding to:
3.-Replace rootfs with Ubuntu rootfs.
We are talking about replacing Console-Image-apalis-imx8.tar.xz with a Ubuntu rootfs and change image.json file, right?
Thank you very much.
Ander.
