Hmm... Have you read this [1]? It may give some hints I think.
[1]: https://edison-fw.github.io/edison-wiki/u-boot-update (look into
known-bugs section)
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)
CPU: Genuine Intel(R) CPU 4000 @ 500MHz
DRAM: 980.6 MiB
WDT: Started with servicing (60s timeout)
MMC: mmc@ff3fc000: 0, mmc@ff3fa000: 1
Loading Environment from MMC... OK
In: serial
Out: serial
Err: serial
Net: No ethernet found.
Hit any key to stop autoboot: 0
Target:ifwi
Partitioning already done...
Partitioning already done...
Saving Environment to MMC... Writing to redundant MMC(0)... OK
dfu_fill_entity: Device raw not (yet) supported!
So I am still missing something?
Yes. You haven't read the Issue #3 [3] mentioned in the known-bug section in
[1].
[3]: https://github.com/intel/edison-u-boot/issues/3
For your convenience copy'n'paste of my comments from [3].
~~~
You need to change mmc word (note that mmcpart word is left untouched) to raw
word in description of partitions. It's done, for example, in
do_dfu_alt_info_mmc environment variable.
Command is kept the same:
dfu 0 mmc 0
~~~
There is no rawpart keyword in DFU if I remember correctly. You need to use
mmcpart instead. I have updated above comment to accent on this.
~~~
This Yocto recipe build U-Boot and the env variables as the original
flashall.sh script expects:
https://github.com/edison-fw/meta-intel-edison/tree/zeus/meta-intel-edison-bsp/recipes-bsp/u-boot/files/target_env
These are concat with this one:
https://github.com/edison-fw/meta-intel-edison/blob/zeus/meta-intel-edison-bsp/recipes-bsp/u-boot/files/edison.env
Scripts and U_Boot built in this way are built and tested up to U-Boot
