uboot无法引导进入系统

uboot编译完毕后,烧录完毕,设备树和根文件系统都装好了,但是uboot无法引导进入系统:

Re: uboot无法引导进入系统

是uboot哪里编译的有问题吗? 烧写命令是:sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

Re: uboot无法引导进入系统

结贴, 是因为suniv.h中需要配置

/* bootcmd 保存着 uboot 默认命令, uboot 倒计时结束以后就会执行 bootcmd 中的命令 */
/* bootargs 保存着 uboot 传递给 Linux 内核的参数*/
sudo nano /include/configs/suniv.h
 
/* 添加以下代码(mmc 0为TF卡,1是第一分区,文件系统为fat32,把zImage和dtb文件拷入DRAM)*/
#define CONFIG_BOOTCOMMAND  "fatload mmc 0:1 0x80800000 zImage; "  \
                            "fatload mmc 0:1 0x83000000 suniv-f1c100s-licheepi-nano.dtb; " \
                            "bootz 0x80800000 - 0x83000000;"
 
/* 继续添加(linux将使用uart0进行交互,死机5s重启,根文件系统在mmc0(tf卡)第二分区(EXT4),等待 mmc 设备初始化完成以后再挂载,开启读写权限) */
#define CONFIG_BOOTARGS   "console=ttyS0,115200 panic=5 root=/dev/mmcblk0p2 rootwait rw "
 
 
/* 回到u-boot目录进行编译 */
make ARCH=arm menuconfig
/* 取消勾选 [] Enable a default value for bootcmd */
/* 勾选 [v] Enable boot arguments;*/
 
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j16
