Pinebook Pro not Booting at All eMMC or MicroSD

[tophneal]

I followed the directions on the wiki for installing U-boot via microSD card images by like afuyam or someone.  It said image a erase spi to microSD, remove the eMMC, and run the microSD.  Then, image a write to spi to microSD and run without eMMC again.  I did those steps but I never got the blinking green light it told me should have happened, so I assume it didn't work.

I have tried all combinations of the eMMC switch being off or on, the eMMC being in or out, and multiple different microSD images.  However, I know the integrity of my microSD images is perfectly fine.  That's definitely not the issue here.  I've been making images for years.

Thanks, AstroCEO.

If you can share a link to the instructions you were trying to follow. I believe the underlying issue here is that you tried to use a u-boot writing tool that was made for another device.
