May it was broken before too?

No problem with u-boot.itb, just the spl_romapi_load_image_stream()
waits for more bytes...

Strange ... I disabled CONFIG_IMX_HAB in my defconfig and now without
this patch U-Boot boots, but uuu stops @ 98% and after a while it shows:

"""
 >Start Cmd:SDPS: boot -f /media/pi/data/srv/tftpboot/xxx/20241010/flash.bin
Wait for Known USB |New USB Device Attached at 1:11313

Error: HID(W): LIBUSB_ERROR_TIMEOUT (-7)



load flash.bin failure
"""

-7 (E2BIG) ?
