U-Boot -> SPI Flash
OpenBSD and loader -> On the eMMC or the MicroSD
The SPI flash is a additional IC on the ROCK64 board. It's an EEPROM which communicates via the SPI interface.
The SPI flash is NOT the eMMC or MicroSD.
The description of the SPI interface
The description of an EEPROM
Sorry, for my adoption. But I think you didn't know what a SPI Flash is.
I have added an attachment where I have marked the SPI Flash on board.
You are largely correct.
"The first step of the tutorial is to install U-Boot in the SPI flash from the ROCK64."
I misread that somehow. Changing the word "from" to "on" (and reading attentively) makes the meaning clear.
I was ignorant of the role of SPI Flash and U-Boot here, hence my bafflement over the set-up of U-Boot.
Thank you for dispelling the confusion.
