ROC-RK3328-CC烧写Debian固件到emmc失败

baicat

1.使用官方镜像和官网下载的2.39版本androidtool
    ROC-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
=>mmc list
rksdmmc@ff520000: 0 (eMMC)

=>part list mmc 1
Card did not respond to voltage select!
mmc_init: -95, time 10
** Bad device mmc 1 **

没有断电，过几十秒，再执行

=>mmc list
rksdmmc@ff520000: 0
rksdmmc@ff500000: 1

=> mmc info
mmc_init: -110, time 72

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
