I have just compiled my Yocto image for my board based on IMX.8.M plus. I need to flash my board using uuu (Universal Update Utility) for nxp imx chips. Each time i launch the following command :

uuu -b emmc_all imx-boot-tagged core-image-minimal-devboard.wic

I have this message :

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.243-0-ged48c51

Wait for Known USB Device Appear...

Note that my board is connected through my laptop with serial port communication.

How to use properly uuu in linux ? Do you have any hint ?

I had to set my board in recovery mode by setting correct switch boot pin. I also had to connect my board through usb type C instead.

I needed to connect my device with a male-male USB-A cable to the PC and set the board in USB serial download mode. Therefore I had to set a pin on the board in high state.
