ROC-RK3328-CC烧写Debian固件到emmc失败
1.使用官方镜像和官网下载的2.39版本androidtoolROC-RK3328-CC_Debian9-Arch64_20180525.img
rk3328_loader_ddr786_v1.06.243.bin
2.根据wiki指导，启动按recovery或短接clk、GND进入maskrom模式，烧写镜像
3.烧写完成进入uboot，但无法启动系统，uboot下命令查看

没有断电，过几十秒，再执行

4.重启开发板，串口就没有输出了，怀疑emmc没有烧写成功
万用表测量emmc各模块电压正常
示波器测试emmc_clk信号，无波形
是不是这个emmc是坏的
进入maskrom模式烧写的log
