may it be done like this?
dd if=/dev/sdb5 of=/dev/mmcblk0
?
i have installed utils
# history | grep mmc-
213 apt install mmc-utils
not sure if you can set partconf with mmc-utils, but 0x1 imho is wrong…afair it should be 0x48, but if emmc boots till uboot…mhm, but it does not look like mine…
try booting in uboot from sdcard and run the mmc partconf
please post full output…it looks like emmc was preflashed, but it should be blank on userparttion after you created the filesystem on mmcblk0 directly without partition.
you need at least boot till uboot from emmc and if uboot itself can read sata drive you can boot from it (afair on r64 uboot was able to access sata).
tried to flash from uboot alone:

you have a usb storage in front-usb-port??
but you can also put the files somewhere else where you can access them from uboot…you can also flash the image from linux to the emmc (/dev/mmcblkX)

for others who try too:
- flash emmc-image from sdcard linux:
gunzip -c /mnt/bpi-r64_emmc.img.gz | dd bs=1M status=progress conv=notrunc,fsync of=/dev/mmcblk0 - boot sdcard-uboot and flash bl2 to boot0 + set boot0 bootable like described here (emmc-header and fip already in the emmc-image so no need to flash again…only for updating uboot fip reflash is needed)

does not booted from SD
have you written bl2 to sdmmc instead of emmc?
i dont know, how to check it ? i writen new SD, not boot
compare beginning of sdcard with unpacked sdmmc image
something like this (untested):
gunzip r64_sdmmc.img.gz
dd if=r64_sdmmc.img bs=1M count=1 | hexdump -C > img.txt
dd if=/dev/sdb bs=1M count=1 | hexdump -C > card.txt
diff img.txt card.txt
tested emmc flash does not affect sdmmc

everything is fine, the card was just erased(i dont know why) and the other one that i recorded turned out to have a faulty r64_header_sdmmc.bin
wait till write process is really finished
Thank you Frank, i`ll wait
Just use the sync command.

i think it`s because it writes to device #1
how to change target device?
Where do you write bl2?
mmc dev 0
switches to mmc device 0 (or use 1 if you want the other).
For bl2 you have to select boot0 via
mmc partconf 0 1 1 1
And the switch to userpart (last 1 to 0)
Currently you only overwrite fip which is already part of image on emmc userpart.
What is your full emmc bootlog?
where i need to write bpi-r64_emmc_fip.bin ? what partconf ?
