机顶盒卡logo用USB_Burning_Tool线刷到9%报错0X30405004。插TTL无限滚动下面信息应该是EMMC出错。GXL:BL1:9ac50e:a1974b;FEAT:ADFC318C;POC:3;RCY:0;EMMC:0;READ:0;CHK:AA;SD:800;USB:8;LOOP:1;EMMC:0;READ:0;CHK:AA;SD:800;USB:8
用Burn_card_maker做卡刷也不行，不过卡里面的UBOOT可以启动，TTL查看到SD卡和EMMC，EMMC版本为4.0, 容量为 7.3GiB，速度52MHz， 8 位宽的总线，mmc part测试EMMC无分区。求大神指导怎么弄。
下为TTL信息和盒子图片（背面黑的地方是C125多次短接焊盘不注意捅掉了刮开直接飞出来微动开关方便短接）
