have reproduced it on my new r64 (preloader gets not loaded and print only bootrom-numbers), bootswitch made no change…
and it looks like same problem we had on r2
root@bpi-r64:~# ./mmc extcsd read /dev/mmcblk0 | grep PARTITION_CONFIG
Boot configuration bytes [PARTITION_CONFIG: 0x00]
root@bpi-r64:~# ./mmc bootpart enable 1 1 /dev/mmcblk0
root@bpi-r64:~# ./mmc extcsd read /dev/mmcblk0 | grep PARTITION_CONFIG
Boot configuration bytes [PARTITION_CONFIG: 0x48]
root@bpi-r64:~#
after that i see preloader booting

[BLDR] Second Bootloader Load Failed
PL fatal error...
i had only flashed preloader till now…
i compiled mmcutils from my 4.14-main branch the following way:
utils/mmc$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make
and uploaded it in the image-dir linked above
Zusammenfassung
btw. on my new r64 i want to try to make boot manually (check bootheaders needed), have now flashed uboot and mbr partition table (from sdcard), but still failing on second bootloader failed

[BLDR] Second Bootloader Load Failed

no idea why now tee2 comes up…maybe we need some more headers on emmc like on sdcard…
sudo dd if=$HEAD0 of=$O bs=512 seek=0 #0
sudo dd if=$HEAD1 of=$O bs=512 seek=1 #512 = 0x200
sudo dd if=$PRELOADER of=$O bs=1k seek=2 #2k = 0x800
sudo dd if=$ATF of=$O bs=1k seek=512 #512k = 0x80000
it seems i need to write all headers above to emmc user-part (also sd-card preloader) to load uboot on emmc
i have added a package with script to initialize emmc (set partition config and write all bootheaders incl. uboot and partitiontable) from a debian-based sdcard-image (uses apt to install dosfstools to format boot-partition)
then you can add any rootfs and kernel to the partitions
