我的sun8i.h的设置文件是下面设置的 求大神看看啊
#define CONFIG_BOOTCOMMAND "setenv bootm_boot_mode sec; " \

这块板子，这张卡烧我做的固件正常?
这个卡是烧的我自己的固件

看上面的 log 降低 MMC 的频率， spl & u-boot 都跑起来了.
再把 u-boot 里面的 DRAM 和 CPU 频率都降下来。
可以直接修改 .config 文件
DRAM 166M
CPU 800M
就是配置这样两个是吧？？
CONFIG_DRAM_CLK=166
CONFIG_SYS_CLK_FREQ=838860800

CONFIG_DRAM_CLK=166
