imx93 UUU starts uboot but dont execute fastboot commands

[spawn]

Hello,

I'm trying to boot and flash an imx93 using uuu, but it's not working.

Uboot starts but then uuu  does not seem to run fastboot commands to flash.

Run built-in script:                                
 uuu_version 0.0.1

 Do you know why ?

ps: once uboot is running, if I run 'fastboot usb 0' , then I can use uuu to run the fastboot commands that did not seem to run before.

I guess I have start fastboot automatically somehow.
