We have a number of network panels on a flight simulator that have this configuration. I would like to capture an image of the current OS (Linux) and bootloader, so I can use to flash replacement or corrupted VF50 modules. Is this possible?
No, this is not easily possible. Colibri VF50 uses raw NAND which does not allow to easily clone on a flash level due to bad blocks.
The officially supported way is to build an image with the changes integrated using OpenEmbedded (core).
It is possible to make a copy of the rootfs content on a file system level, e.g. you could create a special initramfs based image, boot into that, attach the rootfs and tar the complete rootfs. Then you need to boot into that same initramfs based image on the second module, create the exact UBI layout as on the first one, attach to the rootfs and untar the complete rootfs. Toradex does not provide such a initramfs bsaed image right now and we do not have exact steps ready for the whole process.
It is much easier on modules using eMMC (e.g. Colibri iMX6 Solo). Steps for those modules are documented here:
How to Clone Embedded Linux on eMMC Based Toradex Modules
Thanks, that’s what I thought after reading all the info I could find, but wanted to make sure I understood correctly.
So, these modules came to us from a vendor with embedded Linux version 4.4.14. We’ve had two stop working, and it seems the O.S. is corrupt, it will boot to a point where it starts mounting file systems, then freezes. I want to flash the O.S. to see if the modules are still good, but want to make sure I build the correct image.
Any advice?
Hi, can you try to flash the demo image from toradex and check if the module is booting? If not, please share the error log. Thanks.
It starts to boot, but fails before completion. Seems like it freezes when it attempts to mount the root file system. I don’t have the error log but will I do have a Putty session log I captured during boot I will attach. I also have a Putty session log from one of our good boards during boot.
Forgot to answer the question about installing the demo image, all of our VF50 modules are mounted on Viola Plus carriers, so we have ordered an IRIS carrier so we will be able to flash the bad ones.
Below is the Putty session log of our bad VF50 during boot:

Thanks for the information. You should be able to flash the device following the steps on this site. These steps should also work with Viola Board. If this does not work, then you can follow these steps.
Thanks, we were just able to do that and can now get one of the bad ones to boot and accept an IP address and application firmware, but it still won’t work in our installation. I believe there is something unique in the root file system for our installation that we need to add to the image.
Thanks, we were just able to do that and can now get one of the bad ones to boot and accept an IP address and application firmware, but it still won’t work in our installation.
You are welcome. So this means, if you install demo image from toradex, then the module is booting up correctly.
I believe there is something unique in the root file system for our installation that we need to add to the image.
You need to find out, how the image installed on your modules was created. You should ask the vendor.
Yes, we installed the Colibri VF LinuxConsoleImage 2.7 and the module will now boot. When we install it in our device it will accept an IP and communicate, and it will accept the firmware for the specific application it is assigned to perform, but it won’t actually operate the way the application is designed to operate.
I am relatively sure the module is good, we just have to get, or build the correct image for the job the module is supposed to be doing.
These are good news that the module is working correctly. What is your application for the module?
The modules are built into simulated aircraft panels like lighting control, air conditioning, HUD control, and provide input/output data (switch/knob settings) to a host computer that runs an aircraft flight simulator. The panels are all connected with the host computer through a PoE Switch, that also provides power to them.
HI, Thanks for these information.
If you try to run your application with the toradex demo images are there any errors? Can you ask your vendor, how he created the image for the modules?
Because of the way the module is installed in the device we’re not able to monitor a terminal while it is running, so we only see a status for that box. In this case an External Lighting Control, and HUD Control. The box in question reports a “not operational” status.
We’ve asked the owner of the device to query the vendor, I’m just contracted maintenance, so I have to go through the owner to get that info.
Ok, let us know once you got more Information.
