| > git clone https://github.com/rockchip-linux/rkbin.git |
| > dd if=./rkbin/rv1x/rv1108ddr.bin of=ddr.bin bs=4 skip=1 |
| |
| Compile U-Boot |
| =========================== |
| > make CROSS_COMPILE=arm-linux-gnueabi- evb-rv1108_defconfig all |
| > ./tools/mkimage -n rv1108 -T rksd -d ddr.bin spl.bin |
| > cat spl.bin 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 ./rkbin/rv1x/RV1108_usb_boot.bin |
| > rkdeveloptool wl 0x40 u-boot.img |
| > rkdeveloptool RD |
