+ => git clone https://github.com/rockchip-linux/rkbin.git
+
+ - Compile U-Boot
+ => cd /path/to/u-boot
+ => export BL31=/path/to/rkbin/bin/rk33/rk3308_bl31_v2.22.elf
+ => make roc-rk3308-cc_defconfig

+ => cat spl/u-boot-spl.bin >> idbloader.img
+
+3. To build RK3399 board:
Option 1: Package the image with Rockchip miniloader:
Option 2: Package the image with SPL:
- - We need the Python elftools.elf.elffile library for make_fit_atf.py to work
-
- => sudo apt-get install python-pyelftools
-
- Export cross compiler path for aarch64
- Compile ATF
use the existing boot ROM code from SPL.
+Writing to the eMMC with USB on ROC-RK3308-CC
+=============================================
+For USB to work you must get your board into Bootrom mode,
+either by erasing the eMMC or short circuit the GND and D0
+on core board.
+
+Connect the board to your computer via tyepc.

Booting from an SD card
=======================
To write an image that boots from an SD card (assumed to be /dev/mmcblk0):
- ./tools/mkimage -n rk3288 -T rksd -d ./tpl/u-boot-tpl.bin out &&
- cat ./spl/u-boot-spl-dtb.bin >> out &&
- sudo dd if=out of=/dev/mmcblk0 seek=64 &&
+ sudo dd if=idbloader.img of=/dev/mmcblk0 seek=64 &&
sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 seek=16384
Booting from an SD card on RK3188
=================================================
For Rock64 rk3328 board the following three parts are required:
-TPL, SPL, and the u-boot image tree blob. While u-boot-spl.bin and
-u-boot.itb are to be compiled as usual, TPL is currently not
-implemented in u-boot, so you need to pick one from rkbin:
-
- - Get the rkbin
-
- => git clone https://github.com/rockchip-linux/rkbin.git
-
- - Create TPL/SPL image
-
- => tools/mkimage -n rk3328 -T rksd -d rkbin/bin/rk33/rk3328_ddr_333MHz_v1.16.bin idbloader.img
- => cat spl/u-boot-spl.bin >> idbloader.img
+TPL, SPL, and the u-boot image tree blob.
- Write TPL/SPL image at 64 sector
Option 3: Package the image with TPL:
- - Prefix rk3399 header to TPL image
-
- => cd /path/to/u-boot
- => ./tools/mkimage -n rk3399 -T rksd -d tpl/u-boot-tpl-dtb.bin out
-
- - Concatinate tpl with spl
-
- => cd /path/to/u-boot
- => cat ./spl/u-boot-spl-dtb.bin >> out
-
- Write tpl+spl at 64th sector
- => sudo dd if=out of=/dev/sdc seek=64
+ => sudo dd if=idbloader.img of=/dev/sdc seek=64
- Write U-Boot proper at 16384 sector
offset 128KB and the whole image is padded to 4MB which is the SPI flash size.
The position of U-Boot is controlled with this setting in U-Boot:
- #define CONFIG_SYS_SPI_U_BOOT_OFFS (128 << 10)
+ #define CONFIG_SYS_SPI_U_BOOT_OFFS 0x20000
If you have a Dediprog em100pro connected then you can write the image with:
