Hi, I just put miniroot60.fs of the ARM64 snapshot released two days go onto a microSD card, copied the relevant dtb-files to the root (sun50i-a64-pine64.dtb, sun50i-a64-pine64-plus.dtb), and I'm now trying to get my Pine64+ 1GB board to boot but it's a no-go. There's nothing coming off the serial port, not a single character.
It is the default UART0 being used, right? Is there something else I need to do in order to boot from SD card?
