I.MX8ULP EVK failed to boot from all boot device

[charleshuang]

Hi NXP,

I try to use uuu-tool and "LF_v5.15.52-2.1.0_images_IMX8ULPEVK" for burn iMX8ULP demo image.

But I got below SPL log. How can I solve this problem ?

My steps :

 1. Change SW5 to "01xx_xxxx"

 2. Power on the EVK to enter USB download mode.

 3. run "sudo ./uuu -b emmc imx-boot-imx8ulp-9x9-lpddr4-evk-sd.bin-flash_singleboot"

8ulp is still under pre-production, I don't have board to test for you, refer to the user guide:

To use the UUU for i.MX 8ULP EVK, follow the instructions below:
•
To burn single-boot image and rootfs to eMMC, run the following command:
uuu -b emmc_all imx-boot-imx8ulpevk-sd.bin-flash_singleboot_m33 <rootfs.wic.bz2>
