Hi Shirohige, About how to set up/format on SD card ,you can refer to espressobin wiki http://wiki.espressobin.net/tiki-index.php?page=Boot+from+removable+storage+-+Buildroot I assume that you ask how to copy the U-Boot bin to emmc . You can try below:(mmcblk0 is mmc device) echo 0 | tee /sys/block/mmcblk0boot0/force_ro dd if=flash-image.bin of=/dev/mmcblk0boot0 conv=fdatasync Don't forget to change the jumper to eMMC boot mode. I download the Binary from here https://dl.armbian.com/espressobin/u-boot/

I have boot from emmc successfully using espressobin-emmcloader-cpu-1000-ddr4-2cs-1g-atf-g39a62a1-uboot-g14aeedc-20180601-REL.bin which provided by armbian . But the board still can not boot using flash-image-bin which i build as espressobin wiki said. The problem is why their size are very different. The espressobin-emmcloader-cpu-1000-ddr4-2cs-1g-atf-g39a62a1-uboot-g14aeedc-20180601-REL.bin is only 828732 Byte But the image which i build flash-image.bin is 4194304Byte. And the mmc boot partition is only 2M . Thansk

Hi I want to boot from emmc(all bootloader ,rootfs and kernel are in emmc). Now I can boot kernel from SD card and emmc (bootloader in spi nor flash.), and it works well. At present ,I have got the flash-image.bin by ATF using BOOTDEV=EMMCNORM option and copy this one to emmc partition 1(mmcblk0p1 179:1 0 7.3G 0 part) Then i changed the jumper to emmc boot mode and reboot the board ,but uboot can not up .The output just show ">" "E" Can anyone tell me how should I do. Thanks
