Thanks, that gets me a bit closer. Here are my steps:

1. Start with the original 2014 U-Boot from 'flashall.sh --recovery'
2. Boot it and use dfu-util to flash the latest 2020 U-Boot as per edison.rst
3. Set env vars as guessed from the link you provided:

setenv dfu_alt_info "ifwi${hardware_id} raw 0 8192 mmcpart
1;ifwib${hardware_id} raw 0 8192 mmcpart 2;u-boot0 part 0
1;u-boot-env0 part 0 2;u-boot1 part 0 3;u-boot-env1 part 0 4;boot part
0 7;rootfs part 0 8;update part 0 9;home part 0 10;vmlinuz fat 0
7;initrd fat 0 7"
setenv do_dfu_alt_info_ifwi 'setenv dfu_alt_info "ifwi${hardware_id}
raw 0 8192 mmcpart 1;ifwib${hardware_id} raw 0 8192 mmcpart 2"'
setenv do_dfu_alt_info_mmc 'setenv dfu_alt_info "ifwi${hardware_id}
raw 0 8192 mmcpart 1;ifwib${hardware_id} raw 0 8192 mmcpart 2;u-boot0
part 0 1;u-boot-env0 part 0 2;u-boot1 part 0 3;u-boot-env1 part 0
4;boot part 0 7;rootfs part 0 8;update part 0 9;home part 0 10;vmlinuz
fat 0 7;initrd fat 0 7"'
setenv do_flash_ifwi 'run do_dfu_alt_info_ifwi ; dfu 0 raw 3'
setenv do_force_flash_os 'run do_dfu_alt_info_mmc ; sleep 1 ; setenv
do_flash_os_done 1 ; saveenv ; dfu 0 raw 3'

4. Reboot and see:

Unknown boot mode: boot

So I am still missing something?
