Re: How to write u-boot bootloader for Jetson TX1

["Jonathan A. Kollasch" <jakllsch%kollasch.net@localhost>]

Not sure it supports the TX1 or TX2, but...

I've used https://github.com/NVIDIA/tegra-uboot-flasher-manifests
occasionally, it's slightly less bulky than the whole L4T package.

I wasn't able to get it to successfully communicate with my Jetson-TK1
using a NetBSD host; however a Linux host did succeed.
