On development brunch OpenWrt appear new image: openwrt-mediatek-mt7622-bpi_bananapi-r64-rootdisk-squashfs-sysupgrade-emmc.bin.gz . In “.gz” archive located “.bin” image ~500MB. But I dont know how use this image. Can someone explain how use it.
Take a look to https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob_plain;f=target/linux/mediatek/image/gen_mt7622_emmc_img.sh and https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob_plain;f=target/linux/mediatek/files-5.4/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64-rootdisk.dts
It seems that image expects eMMC having following partitions: p0/p1/p2/p3/p4 - service partitions as usual, p5 - kernel, 20M (40960 sectors), p6 - recovery initrd, 10M (20480 sectors), p7 - rootfs.
That image should be written starting from p5 partition, you can do it by u-boot (write kernel image to flash) or using dd if=rootdisk-squashfs-sysupgrade-emmc.bin of=/dev/mmcblk0 bs=512 seek=4096
P.S: you should change device to “Banana Pi R64 (rootdisk)” in openwrt’s menuconfig

Hi, it boot like this, I switch the boot select to 0
Looks like the image is not booted…only preloader
Thanks to remind. I’ll try binwalk and add preloader.
I boot this image from emmc:
1. use https://github.com/m2LiJu/BPI_R64_OpenWRT install_emmc.sh to init the emmc.
2. dd if=rootdisk-squashfs-sysupgrade-emmc.bin of=/dev/mmcblk0 bs=512 seek=4096
there is some dmesg:

according to http://forum.banana-pi.org/t/bpi-r64-openwrt-kernel-5-4-40-running-from-emmc/11087/85
there still be a long way to make this board run as a normal router.
I tried to create 2 extra partitions, then wrote the image: dd of=/dev/mmcblk0 bs=512 seek=4096 if=sysupgrade-emmc.bin
Edit: I got answer from openwrt guys, know error, they are working on fixing it.
