-Copy the SPL to offset 32k and the FIT image containing the payloads
-(U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD
-card.
+Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT

+eMMC
+----

+rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
+help of the Rockchip loader binary.

+NOR-Flash
+---------
+
+Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
+we assume you have a SD-Card with a partition containing the required files
+ready.

+Reboot the system and you should see a U-Boot console on UART0 (115200n8).
