RK3568 boot from internal BootRom, which supports remap function by software
programming. Remap is controlledbyPMU_SGRF_SOC_CON1[12:11]. When remap is set to
2’b01, the BootRom is un-accessible and PMU_SRAM is mapped to address 0xFFFF0000.
When remap is set to 2’b10, the BootRom is un-accessible andSYSTEM_SRAM is mapped to
address 0xFFFF0000
RK3568 provides system boot from off-chip devices such as SDMMC card, eMMC memory,
serial Nandor Norflash. When boot code is not ready in these devices, also provide system
code download into them by USB OTGinterface. All of the boot code will be stored in internal
BootRom. The following is the whole boot procedure for boot code, which will be stored in
BootRomin advance.
The following features are supported.
 Support system boot from the following device:
 Serial Nor Flash, 1bit or 4bits data width(device layout in FSPI IO)
 Serial Nand Flash, 1bit data width(device layout in FSPI IO)
 Asynchronous Flash Interface, 8bits data width
 eMMC Interface, 8bits data width
 SDMMC Card, 4bits data width
 Support system code download by USB OTG
Following figure shows RK3568boot procedure flow.
