Problems with using uuu to burn the system

Zion — Thu, 04 Sep 2025 01:42:04 GMT

Hello, my board is the IMX8QXPC0MEK, and I downloaded LF_v6.6.52-2.2.0_images_IMX8QXPC0MEK. After setting the board to 1, 0, 0, 0 (SERIAL mode), I flashed it on my PC (Ubuntu x86). I only plugged a Type-C cable into J10 of the board, maintaining the voltage and current at 12V and 0.23A. When I typed uuu -lsusb, I saw the following:
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.201-0-g727fc2b

Connected Known USB Devices
Path Chip Pro Vid Pid BcdVersion Serial_no
======================================================================
1:13 MX8QXP SDPS: 0x1FC9 0x012F 0x0002 060B400E8296409

This indicates that uuu is recognized, but after typing sudo uuu uuu.auto, the following error still appears:
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.201-0-g727fc2b

Success 0 Failure 1

1:13-060B400 1/ 1 [HID(W): LIBUSB_ERROR_IO (-1)] SDPS: boot -f imx-boot-imx8qxpc0mek-sd.bin-flash

I'd like to ask the developers what the problem is with my operation and how to effectively resolve this error so that I can flash the system to the eMMC. I very much look forward to your response!

Hi,

Are you using below boot mode?

Can you try to use sudo before uuu?

Best Regards,

Hi,

It seems that you are using i.MX8QXPB0 MEK,can you see 'Si B0 SECO' string around M.2 socket?

You can try to flash B0 binary in this demo image.

Best Regards,
Zhiming

Dear Zhiming_Liu
To be honest, I don't know how to distinguish between c0 and b0, so I took a picture to show you.

Hi,

The i.MX8QXPC0 MEK is not black. You can try to flash B0 image to verify if this is i.MX8QXPB0.
