Install 21RC on BananaPi Bpi-R64

Installing and Using OpenWrt
1

Hi! Can someone guide how to install Openwrt 21RC on Bpi-r64 mmc card? I can install snapshot built but having troubles with 21RC.
What rootdisk-squashfs-sysupgrade-emmc is for? I tried to flash it to /dev/mmcblk0 but it does not work for me.
Device page in wiki is not available anymore.

After sysupgrade I can not boot into new kernel (production).

Using default Uboot config:

switch to partitions #0, OK
mmc0(part 0) is current device

MMC read: dev # 0, block # 81920, count 8 ... 8 blocks read: OK

MMC read: dev # 0, block # 81920, count 6095 ... 6095 blocks read: OK

I suppose there something wrong in uboot config, maybe $loadaddr. I just don't know too much about these things.
