New images being created now – but in the meantime please edit /etc/fstab and make sure it contains
proc /proc proc defaults 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
it will be missing the last 2 lines. Then /boot will be populated after a reboot with the config.txt and the rest of the files from the boot partition.
