U-boot configuration for UUU - Unknown image format!

[abrahim]

Hello,

I can't achieve to compile a working u-boot for uuu tool.I have the following message :

U-Boot 2020.04 (Apr 13 2023 - 11:31:09 +0200)

fastboot - run as a fastboot usb or udp device

Usage:
fastboot [-l addr] [-s size] usb <controller> | udp
addr - address of buffer used during data transfers (0x12C00000)
size - size of buffer used during data transfers (0x7000000)

Can you please support ? You can find my .config; board configuration, and uuu script attached.

By the way, I used the LF_v5.15.71-2.2.0_images_IMX6QPDLSOLOX.zip provided by NXP but I couldn't use the binaries as I need to flash the nand and I use UART2 for debug.

Hi @abrahim,

I hope you are doing well.

From the logs, it seems that the USB device is not properly detected.

Please refer to the below-mentioned community thread.

Hi,

What I understood from the feed is that the person was using a virtual environment, which I'm not, so it's not related.

Please share the .config and the ./board/freescale/mx6sabreauto/mx6sabreauto.c files of the uuu u-boot.

Because I can't use the one provided in the package as I'm not using the same UART, so I don't have any logs to debug.

Best regards,

Aïda

Hi @abrahim,

I hope you are doing well.

From the logs, it is seen that it prints fastboot command usage.
The issue seems to be in the fastboot command in uboot script.

Please remove CONFIG_USB_PORT_AUTO=y from the u-boot configuration.

Please share the .config and the ./board/freescale/mx6sabreauto/mx6sabreauto.c files of the uuu u-boot.
=> One can refer to/configs/mx6solosabreauto_nand_defconfig
