Android 15: fastboot : Waiting for Any device.

Axent — Sat, 28 Jun 2025 17:13:30 GMT

Hello.
I need help.
I have the Compulab board with the image on EMMC that doesn't provide ADB.
I tried to flash the new built image to SD card. This works well and now I can see
adb device with "adb devices" command.
But I want to flash the image to EMMC itself.
When I try do this with image booted from SD, I always have:

Please, help. How can I reflash the EMMC?? Thanks.
Thanks.

Hi,

Thank you for your interest in NXP Semiconductor products,

You can use the uuu script for flashing eMMC.

> uuu_imx_android_flash.sh for Linux OS > uuu_imx_android_flash.bat for Windows OS

Refer to chapter 3.3 Flashing board images.

Regards

Hello.

Thanks for reply.
But now I have another issue with EMMC.
https://community.nxp.com/t5/i-MX-Processors/Android-15-How-to-restore-EMMC/m-p/2125158#M238831
I cannot reflash it through fastboot or uuu (accidentally wrong image downloaded, no uboot)
And now I am searching how to flash empty EMMC or some way to 'copy' booted image from SD card.

Please, help. What should I do to flash bootloader at least to EMMC (or copy from SD).?
I don't have available detected USB device for UUU (EMMC doesn't have the valid bootloader), also fastboot is impossible.
I can just boot from SD card. But I'm really misunderstanding how to rebase my working bootloader from SD to EMMC.

Thanks.

Hi @Axent,

That's the function of UUU, it doesn't require U-boot to enter to fastboot. When the processor boots in serial download mode you can confirm it's UUU can burn eMMC/SD by running

uuu -lsusb

When you cannot access boot pins and the processor fails to fetch boot images, it should enter to serial download, please confirm with the past command.

Regards

Hi,

Are you flashing a built image or did you download a prebuilt? Please try with a prebuilt one.

When running the command without -D option, make sure that all the necessary files are under that directory. Finally, make sure to run the script with sudo.
