|
||
|
|
+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. Upload dtb, image and file system 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 upload jh7110-starfive-visionfive-2-v1.2a.dtb instead.
|
||
|
|
+4. Load and boot the kernel
|
||
|
|
+```
|
