UUU tool is unable to flash image to EMMC using Windows 11

Hi,
I was able to successfully flash the binaries to the eMMC on our custom SOM board (based on the i.MX8QXP processor) using the UUU tool on a Windows 10 system. However, I am unable to perform the same operation on a Windows 11 system.
Could you please help me understand what might be causing this issue?
For your reference, I’ve attached the link from which I downloaded the UUU binary, along with the log that shows the process hanging without any message indicating completion.

Thanks,
Swathi

Hi JorgeCas,
I attempted to flash the eMMC on our custom board from a Windows 11 system using the latest UUU tool (Release uuu_1.5.201) downloaded from the link you shared earlier.
Below is the syntax I have used to flash:
uuu.exe -b emmc_all imx-boot-tagged imx-image-core-agility-20250912121110.rootfs.wic
However, the process seems to hang. I’ve attached the terminal logs for your reference.
When I run the same command/syntax again, it produces the following error also sometimes:
Thank you for your guidance.
Regards,
Swathi

Hello,
Thank you for the clarification.
It is strange that you are not able to flash the same image in the same board using Windows 11, I do not have that issue in my side.
I suggest you check if you have some kind of restrictions in USB port with Windows 11 update.
The scripts are not necessary to flash the image, is an alternative to flash it.
Best regards.

Hello,
You need to flash bootloader and rootfs. For example with out EVKs:
uuu.exe -b emmc_all imx-boot-XXXX-sd.bin-flash_evk imx-image-full-XXXX.wicYou can use the script or the command, just keep in mind that you are using the correct files to flash it.
Best regards.

Hello Jorge,
Please find the below details of images I have used in my custom project.
uuu.exe -b emmc_all imx-boot-tagged imx-image-core-agility-20250912121110.rootfs.wic
where,
imx-boot-tagged is the bootloader image
imx-image-core-agility-20250912121110.rootfs.wic is rootfs file
Please let me know whether the syntax and these file extensions are proper or not.
Also, I have a question regarding the flashing script: could you please confirm whether using a custom UUU script (e.g., emmc_custom_all.uuu or emmc_custom_all.auto) is mandatory for this operation?
Thanks,
Swathi
