Hmm... Have you read this [1]? It may give some hints I think.
Any ideas please?
See above.
Just in case my script [2] to prepare a U-Boot image file suitable for xFSTK.
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:
U-Boot 2020.10-rc3-00012-g9f04a634ef3 (Sep 03 2020 - 07:06:30 -0600)

So I am still missing something?
