Problem booting from SD

[GloriousCoffee]

I installed Manjaro to eMMC yesterday, and thought I'd try xfce edition today.

After downloading and booting the eMMC version of Manjaro Xfce, the Pinebook does nothing (only green power button is on).
I downloaded the Plasma version again and wrote it to the SD card, and it does nothing either anymore.

Its the same SD card I'm using now, as yesterday. What could be the problem?

Unless your SD is bad, it shouldn't be the problem. What img were you last trying to boot, exactly? Have you tried booting any other OSes from SD, yet?

Unbelievable, what a time for the SD card to stop working. I tried flashing the xfce image to a USB stick, and it boots fine.
Sorry for the unnecessary post.
