Apalis iMX8 Device not booting up normally anymore

Apalis iMX8
Ixora Carrier Board

I put my device in Recovery Mode (which I have done successfully multiple times) so that I can flash a different OS using the Toradex Easy Installer. However, this time, my device is running into an error (see output below) which prevents it from booting up normally.

What can I do to remedy this? Of course, I have restarted the device but am still getting the same issue.

Output from the debug console (UART1):

Hi, I’m the Toradex AI Assistant. I’m in early beta, and I would appreciate your feedback.
The Toradex Support team will follow up with you shortly!

Did you like my answer?

:+1: :-1:

It appears that your Apalis iMX8 device is encountering a kernel panic during boot, which is preventing it from starting up normally. This issue can be caused by various factors, including but not limited to, corrupted filesystems, incompatible device tree overlays, or hardware issues.

Given the complexity of the output and the nature of the problem, here are some steps you can take to troubleshoot and potentially resolve the issue:

  1. Reflash the Device: Since you mentioned attempting to flash a different OS using the Toradex Easy Installer, it’s possible that the process did not complete successfully or the image is corrupted. Try reflashing the device with a known good image using the Toradex Easy Installer.

  2. Check Device Tree Overlays: The log mentions applying device tree overlays for HDMI and SPI. If these overlays are incompatible with the kernel version or the hardware configuration, they might cause the system to crash. Review the overlays applied and ensure they are compatible with your kernel version and hardware setup.

  3. Inspect Hardware: Hardware issues, such as faulty RAM or storage, can lead to kernel panics. If possible, inspect the hardware for any obvious faults or try running diagnostics if available.

  4. Review Kernel Configuration: If you have a custom kernel configuration, ensure that it’s compatible with the Apalis iMX8 and doesn’t contain any experimental features that might be unstable.

  5. Serial Console Output: The serial console output you’ve provided is helpful. If you make any changes based on the above suggestions, observe the serial console output for any changes or additional clues that might help diagnose the issue.

  6. Minimal Boot: Attempt to boot the system with a minimal set of drivers and services to isolate the cause. You can do this by modifying the boot arguments if possible.

  7. Check for Known Issues: Review the Toradex community forums and the Torizon issue tracker for any known issues similar to yours. It’s possible that others have encountered this problem and found a solution.

If after following these steps the issue persists, it might be helpful to gather more detailed logs if possible and consider reaching out for more specific support with detailed information about the steps you’ve taken and the results.

Best regards,
Toradex AI Assistant

Could you please clarify if you are getting this error while trying to load the Easy Installer or after you have successfully flashed a new OS image? If it is the latter, could you please specify which exact image you have flashed?

4

@alex.tx I successfully flashed the TorizonCore image previously. When I tried to put it in Recovery Mode again and load the Easy Installer, I got the above error.

5

@alex.tx
I am looking at the link below right now (section “Removing Conflicting DTO”). When the partition shows up on the host machine (drive D: in my Windows 11 machine), it says that the disk needs to be reformatted. Is this expected?
When I decline the reformat,
the next message says,

D:\ is not accessible.

The volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the volume is not corrupted.

Could you please specify the version of the Toradex Easy Installer you’ve tried to load?

@alex.tx
Apalis iMX8 Toradex Easy Installer 6.6.0+build.6

Could you please try version 5.7.6 instead?

Hi @alex.tx , I will use version 5.7.6 Toradex Easy Installer when I get the device out of its current bad state. Currently, the OTG USB doesn’t connect with the host machine.

Question: How do I get the device out of its bad state? I hit “any key to stop autoboot” then sent the command

ums 0 mmc 0

and the partition tries to display on the host machine but my Windows 11 host machine wants me to reformat the disk.

  1. Should I reformat it?

The terminal output:

Apalis iMX8 # ums 0 mmc 0
UMS: LUN 0, dev mmc 0, hwpart 0, sector 0x0, count 0x1da4000
We are in is_imx8
Getting phy ctrl
\

It is perpetually displaying the slashes (/ and \ ) like a spinner. It doesn’t progress from here.

10

Could you please define a bad state? If you are able to stop the boot process at the U-Boot stage, it means the device boots properly and the bootloader works as expected. You may then have some issues with the OS starting. You need to analyze the OS boot log, fix the issue, build a new version of the OS, and then flash it using the Toradex Easy Installer.

The ums 0 mmc 0 command allows you to mount the device’s mmc partition 0 to your host computer, so you can modify its content. You don’t need to reformat it since the Toradex Easy Installer will handle formatting during the new image flashing.

@alex.tx

ok.

Next, I followed the instructions to load Toradex Easy Installer using a USB stick (because the device won’t connect with the host using USB OTG). The GUI for the Toradex Easy Installer doesn’t show on the device’s display.

Loading the Toradex Easy Installer over USB OTG is a recommended way to load it. Do you mind providing details?

  • What is your carrier board?
  • How exactly is it connected to your host machine?
  • How exactly do you put the module into recovery mode?
  • What is the output of the recovery_xxx script on your developer machine?
  • What is the output on the module debug UART?"
14

@alex.tx Hi,

  • Ixora Carrier Board
  • Ixora is connected to the host machine through the USB OTG connector and directly to the host machine’s USB connector. No hub.
  • I put the module in recovery mode by turning the device off, short-circuit-ing recovery jumper JP4 (first two pins closest to “JP4” print), turn on the device, wait 6 seconds, then run the recovery-windows.bat from the host machine.

Output from host machine command prompt:

  • Have you removed JP2 on the Ixora board?
  • When you put the Apalis iMX8 module in recovery mode properly, nothing should be outputted from the debug UART until the OTG download completes successfully. If you see something on the debug UART when the system is powered on in recovery mode, it means it is not actually in recovery mode."
16

@alex.tx Hi, yes, I keep JP2 jumper off.

It was never in Recovery Mode? I tried to re-do Recovery Mode, but I will try, again.

17

@alex.tx
Hi, I put the device in Recovery mode “again” and ran recovery-windows.bat from the host machine. This time, the host and device were able to connect via USB OTG. However, I don’t see the Toradex Easy Installer GUI showing from the device. I’m using a computer monitor connected to the HDMI connector on the Ixora board. Monitor is powered and is on.
