Quartz64 - Boot Order

[FrankM]

The RK3566 boot ROM will search for a valid ID BLOCK in the following order on the support boot media:

• SPI NOR flash
• SPI NAND flash
• eMMC
• SD-Card

... if this fails, the boot ROM will initialize the USB0 port and wait for a connection from the Rockchip flash/boot tools.
