Hi Ronald,

No, it's not about installing FreeBSD from scratch using a USB flash drive
as I already flashed and installed the FreeBSD kernel in the SPI flash RAM
using trivial FTP in the U-boot loader. What I want is mounting the root
filesystem that's been created in the USB flash drive (this hardware has
USB port) using the ufs:/dev/da0s1a method but before that happens, I need
to create that root filesystem (/) from scratch in the USB flash drive so
that it can be mounted right after the kernel is loaded.

Not sure what level I am as a FreeBSD user but I can install and setup
FreeBSD system, networking, install packages and re-build or compile a
kernel.

Thanks and best regards,
Archimedes
