Thanks for explaining.

The LNX partition is getting a boot.img - what is the relation to the
four U-Boot files? flash.sh source is not really helping here.

Might any changes to RP1 and/or DTB partitions be necessary to match my
newer U-Boot, or does U-Boot use an internal .dtb these days?

Is there any more efficient way to flash just U-Boot? -k LNX possibly?

I had played with the -L option before (which mentions u-boot-dtb.bin),
but recall it ran into some form of checksum error on boot when passing
it my file...

Thanks again for your efforts.
