Issues downloading Linux image to iMX93-QSB

[Bob_NXP_user]

I'm tryng to download a Linux image to my iMX93-QSB using UUU in Windows 10. First of all, i installed LF_v6.6.3-1.0.0_images_IMX93EVK from https://www.nxp.com/design/design-center/software/embedded-software/i-mx-software/embedded-linux-for... , then i unzipped it into a folder on Desktop. Then i installed the latest version of uuu.exe from https://github.com/nxp-imx/mfgtools/releases ,placing it in the same folder as the images together with libusb-1.0.dll.

Eventually, I did the following steps:

1. set the boot mode on "Serial Download".

2. turned on the board.

3. I opened cmd as administrator, and wrote:

In this way, I checked USB connection.

4. I used this command in order to start the download:

I can't figure out what's wrong. Can you help me?

Is imx-boot-imx93-9x9-lpddr4-qsb-sd.bin-flash_singleboot the file that contains SPL, U-BOOT, etc.. and correctly compiled for iMX93-QSB Evaluation board?

If not, which one can I use? Should I compile SPL and U-BOOT by myself?

Regards,

Roberto.

Hi @Bob_NXP_user!
Thank you for contacting NXP Support!

Can you open Powershell in administrator mode?

Also, can you try with the command "uuu.exe uuu.auto-imx93-9x9-lpddr4-qsb"

The option emmc_all is to write uboot and rootfs can you try too with "uuu.exe -b emmc imx-boot-imx93-9x9-lpddr4-qsb-sd.bin-flash_singleboot"

Best Regards!

Hi @Chavira, Thanks for replying!

I solved this issue by changing USB drivers and removing my USB hub.

Now I'm able to access the bootloader from serial port, I would like to ask you another question. How can i download dtb and kernel on my board? 

I checked into LF_v6.6.3-1.0.0_images_IMX93EVK folder and i found imx93-9x9-qsb.dtb, i think that's the file i need but I don't know how to download it. Then I was also looking for the kernel file in the same folder but I didn't find it, maybe I just can't recognize it, can you help me?

You can use the "uuu.auto-imx93-9x9-lpddr4-qsb" file, it contains all you need, including dtb and kernel.
Make sure you write file extension into the command line, because when I tried "uuu.exe uuu.auto-imx93-9x9-lpddr4-qsb" it didn't work. So You have to write "uuu.exe uuu.auto-imx93-9x9-lpddr4-qsb.auto-imx93-9x9-lpddr4-qsb". Let me know if you can solve this issue.

Hi

Actually, I am trying to flash the imx93 board as : 

./uuu -b emmc_all imx-boot-imx93-11x11-lpddr4x-evk-sd.bin-flash_singleboot imx-image-full-imx93-11x11-lpddr4x-evk-20240829072649.rootfs.wic.zst/*

but I am also getting this error : 

LIBUSB TIMEOUT ERROR as exactly like you have posted.

You said yos resolved by updating some USB drivers or anything. Please tell me how can I also resolve this issue?

Thanks

Hi,
Basically, if you are using a USB hub I suggest you to remove it and pug your board directly on USB ports. Furthermore you can try to update USB driver using zadig-2.8, as mentioned in UUU guide document (you can find it in also on NXP website).
