Hello All,
We purchased Apalis iMX8 QuadMax 8GB Wi-Fi / Bluetooth IT with Apalis Evaluation Board V1.1Z.
The initial setup was ok and we were able to run applications on the device also. But after 4/5 days of working on it, the system abruptly crashed.
When I view the UART debug terminal, the kernel keep restarting again and again continuously.
We have tried re-installing the Toradex Easy Installer through USB OTG and USB memory as well, as given on the Toradex website, but it does not load the easy installer.
Could anyone please help us?
Hello @sachinkumarbhoi , welcome to the community.
Could you please share with us the UART output that shows these restarts?
Best regards,
Josep
This is the output we are getting with the UART debugger output

Hello @sachinkumarbhoi ,
Did this issue happen after trying to downgrade from Torizoncore 6 to TorizonCore5?
Best regards,
Josep
Hello
No, we didn’t try to downgrade.
I was trying to run an application directly through SSH without (VSCode + Host PC method) by myself in the Apalis board, then suddenly I got disconnected and when I tried connecting again, I could not connect via SSH.
Then we checked the UART output, and we saw that the system is restarting continuously.
Hello @sachinkumarbhoi ,
is that a custom application or one of ours?
Best regrds,
Josep
It is a simple Python code on torizon debian I was trying to run. Also, I was not running any code actively while it happened. It was just connected to SSH.
Hello @sachinkumarbhoi ,
Since your problem might be difficult to reproduce, let’s focus on the recovery procedure.
Can you explain the steps that you took to put the module in recovery mode and load Toradex Easy Installer?
Please also share the output of the recovery script and the debug UART while performing this procedure.
Best regards,
Josep
We have tried two different procedure, both of which is not fruitful
- Loading Toradex Easy Installer | Toradex Developer Center
We connected the OTG port X49 to the computer using the required cable. Our guess is system can’t find the USB device.
- Load Easy Installer From External Media (SD Card/USB Stick) | Toradex Developer Center
We formatted a USB stick and renamed the boot-tezi.scr to boot.scr, and followed the procedure.
The boot fails, and here is attached UART output

Hello @sachinkumarbhoi
Have you ensured that you put the device in recovery mode, as described here?
You have to make sure that you temporarily short the two indicated pads, marked on the picture in order to put the module in recovery mode.
Best regards,
Josep
Hello Joseph
We did the short circuit as it is given on the website. However, the device does not seem to be entering the recovery mode.
Are we missing something?
Regards,
Sachin
How do you verify that the device is not entering recovery mode? Please ensure that the pads are securely shorted before you apply power, and they should be released 6 seconds after the module powers on. You can determine if the module is in recovery mode by the absence of any output on the debug UART.
@alex.tx
We did follow the correct procedure to enter recovery mode. We have verified using UART output, and the UART output never stops.
Hello @sachinkumarbhoi ,
Since the module cannot be put in recovery mode, you can start an RMA as explained here:
Best regards,
Josep
