+3. Package the RK3066 image with U-Boot TPL/SPL on NAND
+-------------------------------------------------------



+Unlike later SoC models the rk3066 BootROM doesn't have SDMMC support.
+If all other boot options fail then it enters into a BootROM mode on the USB OTG port.
+This method loads TPL/SPL on NAND with U-boot and kernel on SD card.



+SD Card
+^^^^^^^



+U-boot expects a GPT partition map and a boot directory structure with files on the SD card.

+Bring device in BootROM mode:



+If bricked and no BootROM mode shows up then connect pin 8 and 9 of the NAND flash
+with a needle while reconnecting to the USB OTG port to a PC.
