So I finally got time to look into this on my PBP and what's happened
is they're moved the offsets the u-boot.itb needs to be written.

So if you do the following for the SPI flash rather than the previous
one it should work:
sf update ${fdt_addr_r} E0000 ${filesize}

A nasty hack that may work is if you use the spi-flashing-disk to
setup a mSD card with the same version that's on the SPI flash it may
boot with that to a U-Boot prompt to save taking it to pieces.

spi-flashing-disk --media=/dev/sda --target=pinebook-pro-rk3399

I am going to update the details in the blog post to cover this, also
we can likely now move to a single command for flashing a combined
blob in F-40. Note I've also discovered a bug in the U-Boot menu if
booting off NVME, I am looking into that currently.
