PBP won't boot (no amber or green LED)

New wrinkle. Seem to be making progress.
Since I was attempting to use rkdeveloptool which requires a USB C cable connected to another computer, I was still trying to power my PBP using my Pinephone charging cable. Totally forgot that there was an AC charger for it.
Turns out that when I found the AC charger and plugged it in, I got a consistent 'power source attached' red light above the F2 key. Previously, using the Pinephone charging cable, the red power light was extremely intermittent.
With the AC charger plugged in, my PBP now powers on reliably and boots from the sd card. So that is wonderful.
However, I cannot seem to get the system to recognize my 64GB emmc card.
On the systemboard there is no 'disable/enable' label for the emmc switch, as I have seen referenced in the documentation and forum posts I have read. Instead there is a 'rectangle' printed on the board which the switch can slide over in one of its two positions. I haven't found any videos or documentation that state whether this 'rectangle' indicates enabled or disabled for the emmc.
I have tried booting and sliding the emmc switch from one position to the other, but so far the system does not recognize the emmc.
Any guidance on exactly how to get the emmc to be recognized would be great.
Thanks for the help so far. I am learning a lot!
