Honestly I am not familiar with imx_usb, we use mfgtool previously and not uuu tool. Would you share where to download imx_usb and any doc, Then we will debug this issue.
You can get imx_usb_loader tool from https://github.com/boundarydevices/imx_usb_loader
Install it, connect the board in USB download mode and then:
sudo ./imx_usb SPL sudo ./imx_usb u-boot-dtb.img
I suggest you to try U-boot 2019.01 first, which works fine and then 2019.04, which is broken.
I could get imx usb loader to successfully load 2019.04 if I manually change the defconfig like this:
