SD cards: 1) 128Gb XC 2) 8GB HC
On a Windows PC, they are defined

2

This is the HC disk. Maybe 128GB XC are not supported or need special driver? Lets wait for an expert...

3

SD reader might require additional packages, like USB support ...

4

is it about the built-in sd card reader?
I have installed: kmod-mmc kmod-mmc-spi

5

I looked at the specifications for SOC Mediatek MT7622 - SD 3.0/SDR104 support has been announced, so the cards should be supported.
For experement by luck, I switched the loading slider to position 0 and lo and behold. The SD cards started to be displayed.

In general, it is strange that so little information is provided (type Banana Pi BPI-R64 boot switch
or -/- sd card support and you will see nothing)
