## Build Instructions ##
1. Configure Kconfig options
```shell
# Use the modified riscv default defconfig
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- defconfig
```
or
```shell
# Select options manually
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- nconfig
```
To boot up the VisionFive 2 board, please make sure **SOC_STARFIVE**,
**CLK_STARFIVE_JH7110_SYS**, **PINCTRL_STARFIVE_JH7110_SYS**,
**SERIAL_8250_DW** are selected.
> If you need MMC and GMAC drivers, you should also select
**MMC_DW_STARFIVE** and **DWMAC_STARFIVE**.
2. Build
```shell
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu-
```
## How to Run on VisionFive 2 Board via Network ##
1. Power on, enter u-boot and set enviroment parameters
```
setenv fdt_high 0xffffffffffffffff; setenv initrd_high 0xffffffffffffffff;
setenv scriptaddr 0x88100000; setenv script_offset_f 0x1fff000; setenv script_size_f 0x1000;
setenv kernel_addr_r 0x84000000; setenv kernel_comp_addr_r 0x90000000; setenv kernel_comp_size 0x10000000;
setenv fdt_addr_r 0x88000000; setenv ramdisk_addr_r 0x88300000;
```
2. Set IP addresses for the board and your tftp server
```
setenv serverip 192.168.w.x; setenv gatewayip 192.168.w.y; setenv ipaddr 192.168.w.z; setenv hostname starfive; setenv netdev eth0;
```
3. Download dtb, image and ramdisk to DDR from your tftp server
```
tftpboot ${fdt_addr_r} jh7110-starfive-visionfive-2-v1.3b.dtb; tftpboot ${kernel_addr_r} Image.gz; tftpboot ${ramdisk_addr_r} initramfs.cpio.gz;
```
> If your VisionFive 2 is v1.2A, you should download jh7110-starfive-visionfive-2-v1.2a.dtb instead.
4. Load and boot the kernel
```
booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
```
When you see the message "buildroot login:", the launch was successful.
You can just input the following accout and password, then continue.
```
buildroot login: root
Password: starfive
```
