Add support for Kevin, an RK3399-based convertible chromebook that is
very similar to Bob. This patch is mostly based on existing support for
Bob, with only minor changes for Kevin-specific things.
Unlike other Gru boards, coreboot sets Kevin's center logic to 925 mV,
so adjust it here in the dts as well. The rk3399-gru-kevin devicetree
has an unknown event code reference which has to be defined, set it
to the Linux counterpart. The new defconfig is copied from Bob with the
diffconfig:
DEFAULT_DEVICE_TREE "rk3399-gru-bob" -> "rk3399-gru-kevin"
DEFAULT_FDT_FILE "rockchip/rk3399-gru-bob.dtb" -> "rockchip/rk3399-gru-kevin.dtb"
VIDEO_ROCKCHIP_MAX_XRES 1280 -> 2400
VIDEO_ROCKCHIP_MAX_YRES 800 -> 1600
+TARGET_CHROMEBOOK_KEVIN y
With this Kevin can boot from SPI flash to a usable U-Boot prompt on the
display with the keyboard working, but cannot boot into Linux for
unknown reasons.
eMMC starts in a working state but fails to re-init, microSD card works
but at a lower-than-expected speed, USB works but causes a hang on
de-init. There are known workarounds to solve eMMC and USB issues.

Building
|
|
--------
|
|
|
|
TF-A
|
|
^^^^
|
|
|
|
TF-A would require to build for ARM64 Rockchip SoCs platforms.
|
|
|
|
To build TF-A::
|
|
|
|
git clone https://github.com/ARM-software/arm-trusted-firmware.git
|
|
cd arm-trusted-firmware
|
|
make realclean
|
|
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399
|
|
|
|
Specify the PLAT= with desired Rockchip platform to build TF-A for.
|
|
|
|
U-Boot
|
|
^^^^^^
|
|
|
|
To build rk3328 boards::
|
|
|
|
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
|
|
make evb-rk3328_defconfig
|
|
make
|
|
|
|
To build rk3288 boards::
|
|
|
|
make evb-rk3288_defconfig
|
|
make
|
|
|
|
To build rk3368 boards::
|
|
|
|
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
|
|
make evb-px5_defconfig
|
|
make
|
|
|
|
To build rk3399 boards::
|
|
|
|
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
|
|
make evb-rk3399_defconfig
|
|
make
|
|
|
|
Flashing
|
|
--------
|
|
|
|
1. Package the image with U-Boot TPL/SPL
|
|
-----------------------------------------
|
|
|
|
SD Card
|
|
^^^^^^^
|
|
|
|
All Rockchip platforms, except rk3128 (which doesn't use SPL) are now
|
|
supporting single boot image using binman and pad_cat.
|
|
|
|
To write an image that boots from an SD card (assumed to be /dev/sda)::
|
|
|
|
sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
|
|
sync
|
|
|
|
eMMC
|
|
^^^^
|
|
|
|
eMMC flash would probe on mmc0 in most of the Rockchip platforms.
|
|
|
|
Create GPT partition layout as defined in configurations::
|
|
|
|
mmc dev 0
|
|
gpt write mmc 0 $partitions
|
|
|
|
Connect the USB-OTG cable between host and target device.
|
|
|
|
Launch fastboot at target::
|
|
|
|
fastboot 0
|
|
|
|
Upon successful gadget connection,host show the USB device like::
|
|
|
|
lsusb
|
|
Bus 001 Device 020: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode
|
|
|
|
Program the flash::
|
|
|
|
sudo fastboot -i 0x2207 flash loader1 idbloader.img
|
|
sudo fastboot -i 0x2207 flash loader2 u-boot.itb
|
|
|
|
Note: for Rockchip 32-bit platforms the U-Boot proper image
|
|
is u-boot-dtb.img
|
|
|
|
SPI
|
|
^^^
|
|
|
|
Generating idbloader for SPI boot would require to input a multi image
|
|
image format to mkimage tool instead of concerting (like for MMC boot).
|
|
|
|
SPL-alone SPI boot image::
|
|
|
|
./tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader.img
|
|
|
|
TPL+SPL SPI boot image::
|
|
|
|
./tools/mkimage -n rk3399 -T rkspi -d tpl/u-boot-tpl.bin:spl/u-boot-spl.bin idbloader.img
|
|
|
|
Copy SPI boot images into SD card and boot from SD::
|
|
|
|
sf probe
|
|
load mmc 1:1 $kernel_addr_r idbloader.img
|
|
sf erase 0 +$filesize
|
|
sf write $kernel_addr_r 0 ${filesize}
|
|
load mmc 1:1 ${kernel_addr_r} u-boot.itb
|
|
sf erase 0x60000 +$filesize
|
|
sf write $kernel_addr_r 0x60000 ${filesize}
|
|
|
|
2. Package the image with Rockchip miniloader
|
|
---------------------------------------------
|
|
|
|
Image package with Rockchip miniloader requires robin [1].
|
|
|
|
Create idbloader.img
|
|
|
|
.. code-block:: none
|
|
|
|
cd u-boot
|
|
./tools/mkimage -n px30 -T rksd -d rkbin/bin/rk33/px30_ddr_333MHz_v1.15.bin idbloader.img
|
|
cat rkbin/bin/rk33/px30_miniloader_v1.22.bin >> idbloader.img
|
|
sudo dd if=idbloader.img of=/dev/sda seek=64
|
|
|
|
Create trust.img
|
|
|
|
.. code-block:: none
|
|
|
|
cd rkbin
|
|
./tools/trust_merger RKTRUST/PX30TRUST.ini
|
|
sudo dd if=trust.img of=/dev/sda seek=24576
|
|
|
|
Create uboot.img
|
|
|
|
.. code-block:: none
|
|
|
|
rbink/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img 0x200000
|
|
sudo dd if=uboot.img of=/dev/sda seek=16384
|
|
|
|
Note:
|
|
1. 0x200000 is load address and it's an optional in some platforms.
|
|
2. rkbin binaries are kept on updating, so would recommend to use the latest versions.
