4.20. Rockchip RK3188¶
4.20.1. Radxa Rock¶
Radxa Rock is a small SBC based on Rockchip RK3188 SoC. See http://radxa.com/Rock for additional information.
4.20.1.1. Building¶
make ARCH=arm radxa_rock_defconfig
make ARCH=arm
4.20.1.2. Creating bootable SD card¶
This will require a DRAM setup blob and additional utilities, see above.
Card layout (block == 0x200 bytes).
| Block Number | Name |
|---|---|
| 0x0000 | DOS partition table |
| 0x0040 | RK bootinfo (BootROM check sector) |
| 0x0044 | DRAM setup routine |
| 0x005C | Bootloader (barebox) |
| 0x0400 | Barebox environment |
| 0x0800 | Free space start |
Instructions.
- Make 2 partitions on SD for boot and root filesystems.
- Checkout and compile https://github.com/apxii/rkboottools
- Get some RK3188 bootloader from https://github.com/neo-technologies/rockchip-bootloader
- Run “rk-splitboot RK3188Loader(L)_V2.13.bin” command. (for example). You will get FlashData file with others. It’s a DRAM setup blob.
- Otherwise it can be borrowed from RK U-boot sources from https://github.com/linux-rockchip/u-boot-rockchip/blob/u-boot-rk3188/tools/rk_tools/3188_LPDDR2_300MHz_DDR3_300MHz_20130830.bin
- Run “rk-makebootable FlashData barebox-radxa-rock.bin rrboot.bin”
- Insert SD card and run “dd if=rrboot.bin of=</dev/sdcard> bs=$((0x200)) seek=$((0x40))”
- SD card is ready
