Error when flashing 8MNano using UUU

[tgibson]

I'm trying to flash a i.MX 8Nano EVK board with the prebuilt linux images using Win10.  I set the jumpers to 1000 for SDP mode.

I run the command:

uuu -v L5.4.70-2.3.0_images_MX8MNEVK.zip/uuu.auto-imx8mnevk

and get the following:

The  8MN evk is LPDDR4 evk or DDR4 evk? 

What is the uart output?

Hi

You can try to unzip the zip file and use command like this:

 uuu -b emmc_all imx-boot-imx8mmevk-sd.bin-flash_evk imx-image-full-imx8mmevk-20200708060549.rootfs.bz2

Thanks for reply.

I tried this command per your suggestion from unzip folder:

"..\uuu.exe" -b emmc_all imx-boot-imx8mnevk-sd.bin-flash_evk imx-image-full-imx8mnevk.tar.bz2

Output is:

Run built-in script:

# These commands will be run when use SPL and will be skipped if no spl

And the UART output is:

U-Boot SPL 2020.04-5.4.70-2.3.0+ge42dee801e (Dec 04 2020 - 00:32:06 +0000)

My packing list says the part is 8MNANOD4-EVK REV A.  Don't how to tell if its LPDDR4  or DDR4.

"Fixed" by using older pre-built.  Had to use "LF_v5.4.y-1.0.1_images_MX8MNEVK.zip".  Can't say I understand the problem (would think newer images are backwards compatible), but this post helped me
