IMX8DXL flashing issue

Tanushree — Tue, 01 Jul 2025 04:29:00 GMT

Hello NXP team,

Our custom board using the i.MX8DXL processor, one of our customers reported a flashing issue when flashing the device using a Windows system. The error appears to be USB-related; however, we have been unable to reproduce the issue on our end. Do you have any suggestions or potential causes that could be related to the customer's laptop?

Below is the logs

Hi @Tanushree

What is your result if you run the uuu -b emmc_all <bootloader> <.wic> command？

Do not choose the uuu script file flash.

Hello @pengyong_zhang

Thank you for the reply.
There doesn't appear to be any issue with the UUU script, as the same procedure works on some laptops. We're using our own custom build. Are there any specific Windows settings that could affect UUU tool flashing or UMS detection?

Regards,
Tanushree

We are encountering an issue where Kernel 6.1.22 is not flashing on Windows 10, whereas it flashes successfully on Windows 11. Could this be due to a lack of support for Windows 10? Additionally, we recently migrated from Kernel version 5.15.52 to 6.1.22. The UUU tool was functioning correctly with version 5.15.52 on Windows 10.

hi @Tanushree

Please share your UUU fail log on Windows10 OS. And what is your uuu version? please use the latest uuu version.

I reviewed the release notes for the Linux 6.1.22 kernel version and noticed that it recommends using UUU version 1.5.21. Currently, I am using the following specific UUU version as shown below:

While flashing works correctly on Windows 11 and Ubuntu 20.04 or later, it fails on Windows 10. However, I did not find any mention of supported or unsupported Windows versions in the release notes—only Ubuntu 20.04 is mentioned.

please try use the uuu -b command flash the image to your board.

Re: IMX8DXL flashing issue

Tanushree — Mon, 14 Jul 2025 08:50:28 GMT

Yes, we tried that as well, but it still fails with the error: 'Failed to open USB device'.

Please try uninstall the USB driver and re install it. It is very strange, i have never meet this problem before.

Tanushree — Tue, 15 Jul 2025 05:47:26 GMT

Hello @pengyong_zhang

In Device Manager, the device is listed under "Other devices" as "USB Download Gadget." Please let us know the specific driver that needs to be installed so we can proceed with testing.

Hi @pengyong_zhang

Is it possible to flash one i.MX8DXL device using another i.MX8DXL device? Has anyone tried this approach before? We would appreciate any suggestions or guidance you may have.

The observations with UUU are the same as what you shared in the last reply.

Hi @Tanushree

Sorry, I talked with our internal team, For now, there is no solution about uuu can not work on win10 but can work fine on win11 and Ubuntu OS.

The best way is using Ubuntu or Win11 OS run the uuu tool.
