Rockchip RK3188 =============== Radxa Rock ---------- Radxa Rock is a small SBC based on Rockchip RK3188 SoC. See http://radxa.com/Rock for additional information. Building ^^^^^^^^ .. code-block:: sh make ARCH=arm radxa_rock_defconfig make ARCH=arm 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= bs=$((0x200)) seek=$((0x40))" * SD card is ready
