May be time to sacrifice an old toaster oven, or to find a hot plate somewhere . . . LOL

Yeah, this chip really wants a well tuned reflow soldering oven!

I'm trying again... this time with 8 resistors. Looks weird, but I can visually inspect every pin.

Ok, it looks strange but it's now working with the card reader. I copied 4 WAV files and 1 PDF to the card.

Happy to report SD listfiles example does see the chip and shows the 5 files I copied onto it with the card reader.

If anyone wants to reproduce this test, see msg #10 for link to the Zetta-to-SD adapter PCB.
