[U-Boot] [PATCH v2 5/7] rockchip: rk3368: add Sheep board
Andy Yan
andy.yan at rock-chips.com
Mon May 15 09:53:50 UTC 2017
Sheep board is designed by Rockchip as a EVB for rk3368.
Currently it is able to boot a linux kernel and system
to console with the miniloader run as fist level loader.
Reviewed-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- add a README to describe how to boot the board

+Here is the step-by-step to boot to U-Boot on rk3368.
+
+Get miniloader and trust.img form rockchip vendor u-boot source code
+==============================================================================
+ > git clone https://github.com/rockchip-linux/u-boot.git rockchip-uboot
+ > cd rockchip-uboot
+ > make rk3368_defconfig /*chose px5_defconfig if you run a px5 platform here*/
+ > ./mkv8.sh
+
+Compile the upstream U-Boot
+===========================
+ > cd u-boot
+ > make CROSS_COMPILE=aarch64-linux-gnu- sheep-rk3368_defconfig all
+
+Package u-boot for miniloader
+================================
+ > ../rockchip-uboot/tools/loaderimage --pack --uboot u-boot.bin u-boot.img
+
+Flash the image by rkdeveloptool
+================================
+rkdeveloptool can get from https://github.com/rockchip-linux/rkdeveloptool.git
+
+Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
+ > rkdeveloptool db ./rockchip-uboot/rk3368_loader_v2.00.256.bin
+ > rkdeveloptool wl 0x6000 ./rockchip-uboot/trust.img
+ > rkdeveloptool wl 0x4000 ./u-boot/u-boot.img
+ > rkdeveloptool RD
+
+You should be able to get U-Boot log message from boot console:
