MK808 is a RK3066-based board with 1 USB host and 1 USB OTG port,
HDMI and a micro-SD card slot. It also includes on-board NAND
and 1GB of SDRAM.
Changed V10:
add u-boot,spl-fifo-mode property
combine patches core support
restyle doc rockchip.rst
add more px30 doc info
add more rk3066 doc info
Changed V9:
fix TABs and spaces
add led config
enable led gpio
change pinctrl regmap source
disable STIMER
move include
Changed V8:
update clock driver
update grf header file
Changed V7:
add board files
enable boot from SD card
restyle pinctrl driver
restyle sdram driver
===
Boot procedure flow for a Rockchip rk3066 SoC:
1.Read 2K SDRAM initialization image code to internal SRAM
2.Run image code to do SDRAM initialization
3.Transfer boot image code to SDRAM
4.Run boot image code
Supported system boot from the following devices:
Nand Flash
SPI nor Flash
eMMC device
UART interface
If all boot options fail then enter into BootROM mode on the USB OTG port.
Unlike later SoC models the rk3066 BootROM doesn't have SDMMC support.
The size of a full U-boot binary is too large for the internal SDRAM memory.
Of that 64k size only 32kb sram - 2kb bootrom is available for the first stage.
Similar to the already supported rk3188, the BootROM will attempt to load up the first stage
image in two steps: first 1KB to offset 0x800 in the SRAM and
then the remainder to offset 0xc00 in the SRAM.
It always enters at offset 0x804 after a 4 ASCII character "RK30" header.
With CONFIG_TPL_ROCKCHIP_EARLYRETURN_TO_BROM=y this first stage is combined with
the U-boot TPL binary (u-boot-tpl.bin).
For rk3066 with NAND flash and U-boot this gives the following stages:
- TPL: init external SDRAM
- SPL: init SDMMC and read U-boot from SD CARD.
- U-boot: read Linux kernel from SD CARD.
- Kernel
Additionally the rk3066 requires everything the BootROM loads to be
RC4-encrypted.
===
Boot solution with full U-boot stored on SD CARD:
Compile commands(U-boot):
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make mk808_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make menuconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make all
===
Size of SPL and TPL must be aligned to 2kb.
If bricked and no BootROM mode shows up then connect pin 8 and 9 of the NAND flash
with a needle while reconnecting to the USB OTG port to a PC.
