pine64-lts - can't detect disk

Hi All,

So between Peter Hessler's post here:
https://bsd.network/@phessler/99389809617980837

And the install instructions for arm64:
https://ftp.openbsd.org/pub/OpenBSD/snapshots/arm64/INSTALL.arm64

I have the pine64-lts:
https://www.pine64.org/?page_id=46823

Booting to the installer, but the sd card disk cannot be located:
Available disks are: none.
Which disk is the root disk? ('?' for details) /dev/rd0a
no such disk
Available disks are: none.
Which disk is the root disk? ('?' for details) /dev/rd0
no such disk
Available disks are: none.
Which disk is the root disk? ('?' for details) ?
Available disks are: none.
Which disk is the root disk? ('?' for details)


Can anyone give some hints on how to have the installer detect the SD
card and for the installation to be completed?

disklabel rd0
# /dev/rrd0c:
