How to use uuu to flash real time prebuilt image to eMMC

[bakbad]

Hello NXP Team,

    I want to test rt data for iMX91P SoC EVK, I hava download a Pre-Built image from Real-Time Edge Software | NXP Semiconductors for iMX9, but use uuu command below can not flash the imx-boot-sd.bin-flash_singleboot into eMMC

uuu.exe -b emmc imx-boot-sd.bin-flash_singleboot

it report errors in windows: LIBUSB_ERROR_PIPE(-9).

What should i do to resove this problem.

Regards,

bakbad

Hello,

Are you using windows or linux?  try with both.

Please try with the images provided in the last pre-build image

sudo uuu -b emmc_all imx-boot-imx91-11x11-lpddr4-evk-sd.bin-flash_singleboot nxp-image-real-time-edge-imx91-11x11-lpddr4-evk.rootfs.wic.zst

Hi,
I have try with both windows and linux. But can not work. The Pre-Built real time Image cant not flash to eMMC.

[bakbad]

Hi,
I used windows. I will try it in linux.
Yes, I download the latest Pre-Built image.
And I just flash bootloader, so i used uuu.exe -b emmc imx-boot-imx91-11x11-lpddr4-evk-sd.bin-flash_singleboot command

Please share a screenshot of the issue on windows.

And the SoC in my board is iMX91P, the product number is PIMX91P3DVVXJAB, Did uuu tool and Pre-Built real-time Image support this SoC?

[Oswalag]

It should, let me try on my side and I'll let you know.

[bakbad]

OK， I‘ll wait

Hello,

I can confirm it worked as expected with the UUU tool in windows, please see below:

Also the board boots correctly. 

[bakbad]

Or can you upload the uuu version used in your PC.

[bakbad]

Also, i see the uuu Release in https://github.com/nxp-imx/mfgtools/releases?page=1, the version uuu_1.5.177 add support for i.MX91.
So why the uuu_1.4.193 can flash the i. MX91?
What's the difference between there?

[Oswalag]

Both versions work on my side, please use the Release uuu_1.5.182 , also try to boot from sd card, before trying to use the uuu tool be sure that your board actually works with a pre-build image, the one in the emmc or a new one booting from sd card. 

[bakbad]

I try to flash the sd card, but had the same error. The uuu version is 1.5.182
LIBUSB_ERROR_PIPE(-9)

Maybe the Pre-built image do not fit iMX91P SoC.
I have no ideas. Thanks a lot.

[Oswalag]

The image works, I have tested it in the i.MX91EVK, please flash the pre-build image using directly a linux host computer with the procedure in the i.MX Linux User’s Guide 

[bakbad]

Use the linux dd command directly? Ok, i'll try with it.

[bakbad]

The SoC is also i.MX91P? I use the same version uuu in your picture but no any logs

[bakbad]

I used uuu -v and logs like this:

Run built-in script:

Also, I had try to connected two usb cable to board, one for serial download and one for debug uart port, while use uuu to flash the image, the debug uart port had no any logs.
