I've some pi's here, they they always id the sd they boot from
as /dev/mmcblk+ an identifier, on both a pi3 and a pi4.
The card readers always sign in ack a dmesg report as /dev/sda|b|c|d etc
plus the partition number. And thats the same for this stretch on amd64
as it is on the pi's. No clue of course how your gigabyte bios might
handle that. I just rebooted this amd64 stretch, I was up to /dev/sdi#
for the card readers. Lots of traffic there as I build boot cards for
the pi's, on the pi's but move the image to this machine about half the
time to write the card. The lack of spare ports on the pi's is the main
reason as I've a pair of ssd's I use as scratchpads when building new
images or debs of linuxcnc. The pi's are actually running machine shop
stuff like metal lathes and multi-axis mills. They run the machines
nicely, but the video on the pi3 is rather glacial. So once its had
another 2 hours to warm up I'll open the garage door for working room
and swap the pi3 running a medium sized (11x54) Sheldon lathe, out for a
pi4 with about 20x faster video.
I may have grown old at 85, but I've never grown up. :)
The reason I stuck my hand up is that the sd cards are generally accessed
via an spi path, whereas the mmc's have a more parallel interface for
higher bandwidth. So to clarify, read the helps for the spi stuff in
your config as something missing there might preclude the proper
detection of the sd hardware.
