[U-Boot] U-Boot and USB 3.0

[DJM-Avalesta]

Hi Bin 

Further to previous, I have built the latest u-boot source from
git.denx.de but, when I flash this version, it fails to boot the kernel.
Here are the debug traces. 

The working u-Boot:-

Any ideas?

When I can build and overwrite u-boot, I will try a more recent version of the u-boot source, but I worry that there may be NVidia-Jetson-specific code in the current version of u-boot.
