Hi,
I have stacked an eInk Feather Friend (https://www.adafruit.com/product/4446) onto a HUZZAH32 (https://www.adafruit.com/product/3619). I have also connected a 2.13" HD Tri-Color eInk Display to the Friend.
I am able to run the FeatherWingTest.ino sketch in Examples->Adafruit EPD. It prints text to the screen, and I can change it, and that's great. But when I try to load my own image, it seems I'm having SD card issues. Even the SD_Test.ino sketch (Examples->SD) prints "Card Mount Failed" to the serial monitor. I have formatted the 64 GB (it's all I have) SD card as FAT32. Googling suggests that I "check my wiring", but since this is a Feather/Wing setup, and since I don't see any instructions for changing any pins on the Adafruit website, I'm not sure what else to try right now.
Any suggestions are appreciated. Many thanks...
Additional wiring (for SD card) for HUZZAH32+eInk Friend?

Ignore the epaper display for the moment, and just try running the example sketches from the SD library. Do those fail the same way?

Yeah, the "Card Mount Failed" error is in the SD_Test sketch (Examples->SD).

Okay, that sounds like a basic connection issue. Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Ok, here you go. Excuse the crappy USB cable, it's all I have at the moment (but it works). All I have done is soldered in stacking headers for the Friend.

Thank you. Can I get a photo of the underside of both boards, showing the solder joints please?

Sure thing. Sorry, took the photos too close to get 800x600, hope this works.
