I'm not sure why I see a 16 MB partition connected by SPI, I guess it's for the bootloader. If I could read the screen it's probably telling me "no image found" or similar, but it's booted that far without problem which is why all the LEDs are lit like it's booted into Linux.
I thought maybe there was space for Linux in the SPI partition, but it's too small, that needs to be on MMC, SD or USB (or network). Thought I'd found a free lunch but no. Raspberry Pi has no MMC, not used to it.
It was a bumpy process getting the Rock64 running so I wasn't going to spend much time on it until it had been up and running for a month. I turn on the TV it's connected to, see that it's still running, flip back to Star Trek and forget about it.
AFAIK SPI is like BIOS on desktop motherboards, its a small partition to set some basic stuff and most importantly to boot a small piece of code to direct booting in the next direction, be it network, emmc, usb etc...without SPI afaik the board dont have enough basic information (and/or drivers) to boot from network or usb as example...so basically its "only" 16mb but also, 16mb is enough for what its meant to do...
PS: i know that compare SPI to BIOS is gross oversimplification, it was just an example...
