UUU under windows 10 64 bit

libuuu_1.3.134-0-g0b47f4d

I am using UUU to flash my iMX8M mini eMMC using:

uuu -b emmc_all imx-boot-imx8mmwasp-emmc.bin fsl-image-qt5-imx8mmwasp.sdcard.bz2/*

This works just fine on my laptop (Windows 10 64bit).

But on another PC (the one I really need to use) ...also Windows 10 64bit it appears to start and makes it through the initial procedure programming the bootloader then makes it SDPV boot jump

then I get:

2:514 1/ 0 [Failure open usb device]

What is going on?

Any ideas why this happens on some Windows Installations (after a while)?

did you not understand the question? It attaches and works fine through the first part of the programming it's only the second part where it apparently forces a reboot then downloads the rest. I bet its some timing issue where UUU is not waiting long enough for the host to reattach or something.

it seems your PC doesn't recognized the board when jump, that's why I asked you to checking the device manager, this shouldn't be a uuu tool issue, I don't know if  your PC has usb driver issue, maybe you can send the log file to me, I tested download image to board by uuu on my windows10 64bits laptop successfully, but I don't use the same command as yours

pls check if "Human Interface Devices" detected the new device in the "Device Manager" when you connect board to the PC?

Does anyone have a solution for this issue?
I have the same issue, but I am 100% that it worked before and now since a few weeks it fails with exectly the same error.
Is that probably caused by a Windows Update?

Solution: https://github.com/nxpfrankli/mfgtoolwiki/blob/master/How-to-use-UUU-on-Windows.md
1. Turn on the board
Connect the USB power supply to the J302 connector (the USB Type-C POWER connector)
Connect the USB Type-C cable to the serial download connector (J301) to the host machine
Connect the serial debug (connector J901) to the host machine using a USB micro-B cable
Set the boot mode switches to the Download Mode (see sticker or silk on the board)
Turn on the board on ON/OFF switch (SW101)
2. Open CMD
3. Navigate to the folder with the uuu.exe, uuu.auto, libusb-1.0.dll, and the images to be installed on the target.
4. Execute uuu.exe

Have u tested to run uuu with some extra parameters?

-v   verbose with more screen output. -V should print put more libusb messages

-t Timeout seconds waiting for known usb devices

-T timeout seconds for wait next known usb devices at stage switch (this option might fix your problem)

-pp usb polling period milliseconds
