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?

Hi @Bob_NXP_user!

The UUU tool flashes the dtbs and kermel.
