imx8ulp EVK-HID(W): LIBUSB_ERROR_PIPE (-9)

MadKEm — Fri, 08 Aug 2025 08:21:23 GMT

Hi, i am following up the Getting Started with the i.MX 8ULP EVK document. In the part of loading bsp image into board using uuu.exe, i get an error which is HID(W): LIBUSB_ERROR_PIPE (-9) . the commands ı tried to execute are : uuu -b emmc_all imx-boot-imx8ulpevk-sd.bin-flash_singleboot_m33 and uuu.exe LF_v6.12.20-2.0.0_images_IMX8ULPEVK.zip. In the both execute i get the same error and in the serial port of the linux core, it says: [ERROR] DFI error. Please check DDR configuration. What could be the reason and solution?

Hi @MadKEm

you should run the uuu -b emmc < flash.bin>, or uuu -b emmc_all <.wic image>

please run the uuu -h see the uuu UG.

Hello @pengyong_zhang

I even tried that but it didn't work. So, after all of this I downloaded Linux and followed the process below:

I downloaded the following packages and binaries to create the standalone image(flash.bin): uboot-imx.git, imx-atf.git, firmware-sentinel-0.10.bin and firmware-upower-1.3.0.bin. I have extracted all the required files from the mentioned packages to create the flash.bin. I used VSCode and imported evk9mimx8ulp_hello_world_cm33 project. I renamed the hello_world.bin to m33_image.bin. Then used imx-mkimage with the following command to generate the flash.bin "make SOC=iMX8ULP REV=A2 flash_singleboot_m33". Then used "uuu -b emmc flash.bin" but after this ı get HID(W):LIBUSB_ERROR_TIMEOUT. In the serial port it prints:

"invalid container image

Download -65712, Total size 0

ROM download failure -65712

Wrong Container, no image foundSPL: failed to boot from all boot devices"

These are the files that I use the generate the .bin file: mx8ulpa2-ahab-container.img, upower_a1.bin (fimware-upower-1.3.0), bl31.bin , u-boot.bin, u-boot-spl.bin and the m33_image.bin. Used command "make imx8ulp_evk_defconfig " to generate the u boot files.

I was able to program it currently. The problem was related to the released version of the packages. I downloaded the meta-imx Release - Linux 6.12.20-2.0.0 and extracted all the required files to build the flash image. Then it worked. The "ROM download failure" problem looks like it is related to u boot binaries.
