I take it this is the problem?

For R-Car H3 ES1.0, I currently use the addresses below:

    tftpboot 0x60000000 h3-salvator-x/Image
    tftpboot 0x68000000 h3-salvator-x/r8a77950-salvator-x.dtb
    booti 0x60000000 - 0x68000000

For R-Car H3 ES2.0 (and other R-Car Gen3 SoCs), I use other addresses:

    tftpboot 0x50000000 h3-salvator-xs/Image
    tftpboot 0x58000000 h3-salvator-xs/r8a77951-salvator-xs.dtb
    booti 0x50000000 - 0x58000000

The firmware on your H3 ES1.1 board (Rev.1.0.16) is newer than on my
ES1.0 board (Rev.1.0.12), so it's possible the second version works on
your board, too.

If these work for you, I'll update https://elinux.org/R-Car/Boards/Salvator-X[S]
