Chip

ICE is a XuanTie C910 based high performance SoC board developed by T-Head. The ICE SoC has integrated 3 XuanTie C910 cores (RISC-V 64) and 1 GPU core; featuring speed and intelligence with a high cost-effective ratio. The chip can provide [email protected] HEVC/AVC/JPEG decoding ability, and varieties of high-speed interfaces and peripherals for controlling and data exchange; suits for 3D graphics, visual AI and multimedia processing.

Board

RVB-ICE is development board based on ICE. It is equipped with 7-inch LCD touch screen, integrates WIFl and GMACnetwork communication interface, has 16GB EMMC memory, and supports interfaces such as Bluetooth keyboard and mouse.

The board detail and pre-order link can be found in page: RVB-ICE

QUICKSTART

This port is based on android10-release (platform/manifest 1c222b02bde285fe1272b4440584750154d3882d). All the source code developed by T-Head is contained in the repository, anyone interested in this project can reproduce the environment with RVB-ICE/emulator.

Before downloading AOSP source code please check you work environment, it is recommended to install a Linux system(Ubuntu 16.04 is preferred) with at list 200G disk space and more than 8 CPU cores. Then follow the instructions from the links below:

https://source.android.com/setup/develop#installing-repo

https://source.android.com/setup/build/initializing

To setup the build enviroment, run reproduce.sh to download aosp to current directory and build AOSP for RISC-V. If repo sync is aborted, re-run the script.

Setup emulator environment

Run the reproduce.sh with no argument, the reproduce.sh will lunch the config "aosp_riscv64-eng", and compile all the required images for emulator environment.

Finally, use the following command to start emulator:

cd ${AOSP_RISCV_BUILD_TOP}
source ./build/envsetup.sh
lunch aosp_riscv64-eng
emulator -selinux permissive -qemu -smp 2 -m 3800M -bios ${AOSP_RISCV_BUILD_TOP}/prebuilts/qemu-kernel/riscv64/ranchu/fw_jump.bin

Setup RVB-ICE environment

Prepare binaries

Run the reproduce.sh with an argument "ice", the reproduce.sh will lunch the config "ice910dk-userdebug", and compile all the required images for the RVB-ICE.

The final images will be under:

aosp/out/target/product/ice910dk/
aosp/device/thead/thead_ice910/kernel/

The required image files include:
ramdisk.img
kernel
system.img
thead-ice910.dtb
u-boot-with-spl.bin
userdata.img
vendor.img

Copy these file to fastboot dir:
 mkdir fastboot
 cp aosp/out/target/product/ice910dk/ramdisk.img fastboot/boot
 cp aosp/out/target/product/ice910dk/kernel fastboot/boot/uImage
 cp aosp/out/target/product/ice910dk/system.img fastboot

 cp aosp/device/thead/thead_ice910/kernel/fw_jump.bin fastboot/boot
 cp aosp/device/thead/thead_ice910/kernel/u-boot-with-spl.bin fastboot
 cd fastboot

Create boot image:

 make_ext4fs -l 20M boot.ext4 boot/

Program the device

Connect the power socket to 5V power supply, and the USB Type-C connector to host computer.

rvb_ice_port.jpg

You can program the device with the files under fastboot directory or prebuilt images downloaded from this link: Prebuilt images

Press the reboot button on the board; type in any key to get into console mode when the following prompt shows on the terminal.

Build kernel & u-boot

The kernel and u-boot images are under the prebuilt directory, it is required to recompile these files from the source if you want to change the configurations.

Export the aosp-riscv directory for copy reference.

cd aosp-riscv
