U-Boot Parameter Configuration

Follow the steps below to configure the U-boot parameters for Linux boot.
  1. Use the following command to switch IO voltage to 3.3 V. 
    mw.l 0x1303000c 0x0 0x1
  2. Set IP address and gateway address according to actual application environments.
    The following code block provides an example based on the test environment. 
    setenv bootfile vmlinuz; 
setenv fdt_addr_r 0x48000000;
setenv fdt_high 0xffffffffffffffff; 
setenv fdtcontroladdr 0xffffffffffffffff; 
setenv initrd_high 0xffffffffffffffff; 
setenv kernel_addr_r 0x44000000; 
setenv fileaddr a0000000; 
setenv ipaddr 192.168.125.211; 
setenv gatewayip 192.168.125.1; 
setenv serverip 192.168.125.139;
setenv kernel_comp_addr_r 0xb0000000;
setenv kernel_comp_size 0x10000000
  3. Use the following command to boot Linux. 
    tftpboot ${fdt_addr_r} jh7110-visionfive-v2-pcie-i2s-sd.dtb;
tftpboot ${kernel_addr_r} Im-age.gz;
tftpboot ${ramdisk_addr_r} initramfs.cpio.gz;
booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
